chore(h5): 移除项目内 vendored 技能库及锁文件

删除 software/h5-uniapp/.agents/skills 与 software/h5-uniapp/agent/skills(各 629 文件,来源 uni-helper/skills 的 Vue/uni-app 技能包),并删除 skills-lock.json。两份技能库内容除 9 个 SKILL.md 的前置元数据格式外完全重复,属仓库内冗余副本;开发期技能改由全局技能目录加载。

# Pinia
Pinia is the official state management library for Vue, designed to be intuitive and type-safe. It supports both Options API and Composition API styles, with first-class TypeScript support and devtools integration.
> The skill is based on Pinia v3.0.4, generated at 2026-01-28.

## Key Recommendations
- **Prefer Setup Stores** for complex logic, composables, and watchers
- **Use `storeToRefs()`** when destructuring state/getters to preserve reactivity
- **Actions can be destructured directly** - they're bound to the store
- **Call stores inside functions** not at module scope, especially for SSR
- **Add HMR support** to each store for better development experience
- **Use `@pinia/testing`** for component tests with mocked stores

description: Enable HMR to preserve store state during development
---
# Hot Module Replacement (HMR)
Pinia supports HMR to edit stores without page reload, preserving existing state.
## Setup
Add this snippet after each store definition:
```ts
import { defineStore, acceptHMRUpdate } from 'pinia'
export const useAuth = defineStore('auth', {
// store options...
})
if (import.meta.hot) {
import.meta.hot.accept(acceptHMRUpdate(useAuth, import.meta.hot))
}
```
## Setup Store Example
```ts
import { defineStore, acceptHMRUpdate } from 'pinia'
export const useCounterStore = defineStore('counter', () => {
const count = ref(0)
const increment = () => count.value++
return { count, increment }
})
if (import.meta.hot) {
import.meta.hot.accept(acceptHMRUpdate(useCounterStore, import.meta.hot))
}
```
## Bundler Support
- **Vite:** Officially supported via `import.meta.hot`
- **Webpack:** Uses `import.meta.webpackHot`
- Any bundler implementing the `import.meta.hot` spec should work
## Nuxt
With `@pinia/nuxt`, `acceptHMRUpdate` is auto-imported but you still need to add the HMR snippet manually.
## Benefits
- Edit store logic without losing state
- Add/remove state, actions, and getters on the fly
- Faster development iteration

name: nuxt-integration
description: Using Pinia with Nuxt - auto-imports, SSR, and best practices
---
# Nuxt Integration
Pinia works seamlessly with Nuxt 3/4, handling SSR, serialization, and XSS protection automatically.
## Installation
```bash
npx nuxi@latest module add pinia
```
This installs both `@pinia/nuxt` and `pinia`. If `pinia` isn't installed, add it manually.
> **npm users:** If you get `ERESOLVE unable to resolve dependency tree`, add to `package.json`:
> ```json
> "overrides": { "vue": "latest" }
> ```
## Configuration
```ts
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@pinia/nuxt'],
})
```
## Auto Imports
These are automatically available:
- `usePinia()` - get pinia instance
- `defineStore()` - define stores
- `storeToRefs()` - extract reactive refs
- `acceptHMRUpdate()` - HMR support
**All stores in `app/stores/` (Nuxt 4) or `stores/` are auto-imported.**
### Custom Store Directories
```ts
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@pinia/nuxt'],
pinia: {
storesDirs: ['./stores/**', './custom-folder/stores/**'],
},
})
```
## Fetching Data in Pages
Use `callOnce()` for SSR-friendly data fetching:
```vue
<script setup>
const store = useStore()
// Run once, data persists across navigations
await callOnce('user', () => store.fetchUser())
</script>
```
### Refetch on Navigation
```vue
<script setup>
const store = useStore()
// Refetch on every navigation (like useFetch)
await callOnce('user', () => store.fetchUser(), { mode: 'navigation' })
</script>
```
## Using Stores Outside Components
In navigation guards, middlewares, or other stores, pass the `pinia` instance:
```ts
// middleware/auth.ts
export default defineNuxtRouteMiddleware((to) => {
const nuxtApp = useNuxtApp()
const store = useStore(nuxtApp.$pinia)
if (to.meta.requiresAuth && !store.isLoggedIn) {
return navigateTo('/login')
}
})
```
Most of the time, you don't need this - just use stores in components or other injection-aware contexts.
## Pinia Plugins with Nuxt
Create a Nuxt plugin:
```ts
// plugins/myPiniaPlugin.ts
import { PiniaPluginContext } from 'pinia'
function MyPiniaPlugin({ store }: PiniaPluginContext) {
store.$subscribe((mutation) => {
console.log(`[🍍 ${mutation.storeId}]: ${mutation.type}`)
})
return { creationTime: new Date() }
}
export default defineNuxtPlugin(({ $pinia }) => {
$pinia.use(MyPiniaPlugin)
})
```

---
# Server Side Rendering (SSR)
Pinia works with SSR when stores are called at the top of `setup`, getters, or actions.
> **Using Nuxt?** See the [Nuxt integration](advanced-nuxt.md) instead.
## Basic Usage
```vue
<script setup>
// ✅ Works - pinia knows the app context in setup
const main = useMainStore()
</script>
```
## Using Store Outside setup()
Pass the `pinia` instance explicitly:
```ts
const pinia = createPinia()
const app = createApp(App)
app.use(router)
app.use(pinia)
router.beforeEach((to) => {
// ✅ Pass pinia for correct SSR context
const main = useMainStore(pinia)
if (to.meta.requiresAuth && !main.isLoggedIn) {
return '/login'
}
})
```
## serverPrefetch()
Access pinia via `this.$pinia`:
```ts
export default {
serverPrefetch() {
const store = useStore(this.$pinia)
return store.fetchData()
},
}
```
## onServerPrefetch()
Works normally:
```vue
<script setup>
const store = useStore()
onServerPrefetch(async () => {
await store.fetchData()
})
</script>
```
## State Hydration
Serialize state on server and hydrate on client.
### Server Side
Use [devalue](https://github.com/Rich-Harris/devalue) for XSS-safe serialization:
```ts
import devalue from 'devalue'
import { createPinia } from 'pinia'
const pinia = createPinia()
const app = createApp(App)
app.use(router)
app.use(pinia)
// After rendering, state is available
const serializedState = devalue(pinia.state.value)
// Inject into HTML as global variable
```
### Client Side
Hydrate before any `useStore()` call:
```ts
const pinia = createPinia()
const app = createApp(App)
app.use(pinia)
// Hydrate from serialized state (e.g., from window.__pinia)
if (typeof window !== 'undefined') {
pinia.state.value = JSON.parse(window.__pinia)
}
```
## SSR Examples
- [Vitesse template](https://github.com/antfu/vitesse/blob/main/src/modules/pinia.ts)
- [vite-plugin-ssr](https://vite-plugin-ssr.com/pinia)
## Key Points
1. Call stores inside functions, not at module scope
2. Pass `pinia` instance when using stores outside components in SSR
3. Hydrate state before calling any `useStore()`
4. Use `devalue` or similar for safe serialization
5. Avoid cross-request state pollution by creating fresh pinia per request

# Using Stores Outside Components
Stores need the `pinia` instance, which is automatically injected in components. Outside components, you may need to provide it manually.
## Single Page Applications
Call stores **after** pinia is installed:
```ts
import { useUserStore } from '@/stores/user'
import { createPinia } from 'pinia'
import { createApp } from 'vue'
import App from './App.vue'
// ❌ Fails - pinia not created yet
const userStore = useUserStore()
const pinia = createPinia()
const app = createApp(App)
app.use(pinia)
// ✅ Works - pinia is active
const userStore = useUserStore()
```
## Navigation Guards
**Wrong:** Call at module level
```ts
import { createRouter } from 'vue-router'
const router = createRouter({ /* ... */ })
// ❌ May fail depending on import order
const store = useUserStore()
router.beforeEach((to) => {
if (store.isLoggedIn) { /* ... */ }
})
```
**Correct:** Call inside the guard
```ts
router.beforeEach((to) => {
// ✅ Called after pinia is installed
const store = useUserStore()
if (to.meta.requiresAuth && !store.isLoggedIn) {
return '/login'
}
})
```
## SSR Applications
Always pass the `pinia` instance to `useStore()`:
```ts
const pinia = createPinia()
const app = createApp(App)
app.use(router)
app.use(pinia)
router.beforeEach((to) => {
// ✅ Pass pinia instance
const main = useMainStore(pinia)
if (to.meta.requiresAuth && !main.isLoggedIn) {
return '/login'
}
})
```
## serverPrefetch()
Access pinia via `this.$pinia`:
```ts
export default {
serverPrefetch() {
const store = useStore(this.$pinia)
return store.fetchData()
},
}
```
## onServerPrefetch()
Works normally in `<script setup>`:
```vue
<script setup>
const store = useStore()
onServerPrefetch(async () => {
// ✅ Just works
await store.fetchData()
})
</script>
```
## Key Takeaway
Defer `useStore()` calls to functions that run after pinia is installed, rather than calling at module scope.

# Testing Stores
## Unit Testing Stores
Create a fresh pinia instance for each test:
```ts
import { setActivePinia, createPinia } from 'pinia'
import { useCounterStore } from '../src/stores/counter'
describe('Counter Store', () => {
beforeEach(() => {
setActivePinia(createPinia())
})
it('increments', () => {
const counter = useCounterStore()
expect(counter.n).toBe(0)
counter.increment()
expect(counter.n).toBe(1)
})
})
```
### With Plugins
```ts
import { setActivePinia, createPinia } from 'pinia'
import { createApp } from 'vue'
import { somePlugin } from '../src/stores/plugin'
const app = createApp({})
beforeEach(() => {
const pinia = createPinia().use(somePlugin)
app.use(pinia)
setActivePinia(pinia)
})
```
## Testing Components
Install `@pinia/testing`:
```bash
npm i -D @pinia/testing
```
Use `createTestingPinia()`:
```ts
import { mount } from '@vue/test-utils'
import { createTestingPinia } from '@pinia/testing'
import { useSomeStore } from '@/stores/myStore'
const wrapper = mount(Counter, {
global: {
plugins: [createTestingPinia()],
},
})
const store = useSomeStore()
// Manipulate state directly
store.name = 'new name'
store.$patch({ name: 'new name' })
// Actions are stubbed by default
store.someAction()
expect(store.someAction).toHaveBeenCalledTimes(1)
```
## Initial State
Set initial state for tests:
```ts
const wrapper = mount(Counter, {
global: {
plugins: [
createTestingPinia({
initialState: {
counter: { n: 20 }, // Store name → initial state
},
}),
],
},
})
```
## Action Stubbing
### Execute Real Actions
```ts
createTestingPinia({ stubActions: false })
```
### Selective Stubbing
```ts
// Only stub specific actions
createTestingPinia({
stubActions: ['increment', 'reset'],
})
// Or use a function
createTestingPinia({
stubActions: (actionName, store) => {
if (actionName.startsWith('set')) return true
return false
},
})
```
### Mock Action Return Values
```ts
import type { Mock } from 'vitest'
// After getting store
store.someAction.mockResolvedValue('mocked value')
```
## Mocking Getters
Getters are writable in tests:
```ts
const pinia = createTestingPinia()
const counter = useCounterStore(pinia)
counter.double = 3 // Override computed value
// Reset to default behavior
counter.double = undefined
counter.double // Now computed normally
```
## Custom Spy Function
If not using Jest/Vitest with globals:
```ts
import { vi } from 'vitest'
createTestingPinia({
createSpy: vi.fn,
})
```
With Sinon:
```ts
import sinon from 'sinon'
createTestingPinia({
createSpy: sinon.spy,
})
```
## Pinia Plugins in Tests
Pass plugins to `createTestingPinia()`:
```ts
import { somePlugin } from '../src/stores/plugin'
createTestingPinia({
stubActions: false,
plugins: [somePlugin],
})
```
**Don't use** `testingPinia.use(MyPlugin)` - pass plugins in options.
## Type-Safe Mocked Store
```ts
import type { Mock } from 'vitest'
import type { Store, StoreDefinition } from 'pinia'
function mockedStore<TStoreDef extends () => unknown>(
useStore: TStoreDef
): TStoreDef extends StoreDefinition<infer Id, infer State, infer Getters, infer Actions>
? Store<Id, State, Record<string, never>, {
[K in keyof Actions]: Actions[K] extends (...args: any[]) => any
? Mock<Actions[K]>
: Actions[K]
}>
: ReturnType<TStoreDef> {
return useStore() as any
}
// Usage
const store = mockedStore(useSomeStore)
store.someAction.mockResolvedValue('value') // Typed!
```
## E2E Tests
No special handling needed - Pinia works normally.

name: stores
description: Defining stores, state, getters, and actions in Pinia
---
# Pinia Stores
Stores are defined using `defineStore()` with a unique name. Each store has three core concepts: **state**, **getters**, and **actions**.
## Defining Stores
### Option Stores
Similar to Vue's Options API:
```ts
import { defineStore } from 'pinia'
export const useCounterStore = defineStore('counter', {
state: () => ({
count: 0,
name: 'Eduardo',
}),
getters: {
doubleCount: (state) => state.count * 2,
},
actions: {
increment() {
this.count++
},
},
})
```
Think of `state` as `data`, `getters` as `computed`, and `actions` as `methods`.
### Setup Stores (Recommended)
Uses Composition API syntax - more flexible and powerful:
```ts
import { ref, computed } from 'vue'
import { defineStore } from 'pinia'
export const useCounterStore = defineStore('counter', () => {
const count = ref(0)
const name = ref('Eduardo')
const doubleCount = computed(() => count.value * 2)
function increment() {
count.value++
}
return { count, name, doubleCount, increment }
})
```
In Setup Stores: `ref()` → state, `computed()` → getters, `function()` → actions.
**Important:** You must return all state properties for Pinia to track them.
### Using Stores
```vue
<script setup>
import { useCounterStore } from '@/stores/counter'
const store = useCounterStore()
// Access: store.count, store.doubleCount, store.increment()
</script>
```
### Destructuring with storeToRefs
```vue
<script setup>
import { storeToRefs } from 'pinia'
import { useCounterStore } from '@/stores/counter'
const store = useCounterStore()
// ❌ Breaks reactivity
const { name, doubleCount } = store
// ✅ Preserves reactivity for state/getters
const { name, doubleCount } = storeToRefs(store)
// ✅ Actions can be destructured directly
const { increment } = store
</script>
```
---
## State
State is defined as a function returning the initial state.
### TypeScript
Type inference works automatically. For complex types:
```ts
interface UserInfo {
name: string
age: number
}
export const useUserStore = defineStore('user', {
state: () => ({
userList: [] as UserInfo[],
user: null as UserInfo | null,
}),
})
```
Or use an interface for the return type:
```ts
interface State {
userList: UserInfo[]
user: UserInfo | null
}
export const useUserStore = defineStore('user', {
state: (): State => ({
userList: [],
user: null,
}),
})
```
### Accessing and Modifying
```ts
const store = useStore()
store.count++
```
```vue
<input v-model="store.count" type="number" />
```
### Mutating with $patch
Apply multiple changes at once:
```ts
// Object syntax
store.$patch({
count: store.count + 1,
name: 'DIO',
})
// Function syntax (for complex mutations)
store.$patch((state) => {
state.items.push({ name: 'shoes', quantity: 1 })
state.hasChanged = true
})
```
### Resetting State
Option Stores have built-in `$reset()`. For Setup Stores, implement your own:
```ts
export const useCounterStore = defineStore('counter', () => {
const count = ref(0)
function $reset() {
count.value = 0
}
return { count, $reset }
})
```
### Subscribing to State Changes
```ts
cartStore.$subscribe((mutation, state) => {
mutation.type // 'direct' | 'patch object' | 'patch function'
mutation.storeId // 'cart'
mutation.payload // patch object (only for 'patch object')
localStorage.setItem('cart', JSON.stringify(state))
})
// Options
cartStore.$subscribe(callback, { flush: 'sync' }) // Immediate
cartStore.$subscribe(callback, { detached: true }) // Keep after unmount
```
---
## Getters
Getters are computed values, equivalent to Vue's `computed()`.
### Basic Getters
```ts
getters: {
doubleCount: (state) => state.count * 2,
}
```
### Accessing Other Getters
Use `this` with explicit return type:
```ts
getters: {
doubleCount: (state) => state.count * 2,
doublePlusOne(): number {
return this.doubleCount + 1
},
},
```
### Getters with Arguments
Return a function (note: loses caching):
```ts
getters: {
getUserById: (state) => {
return (userId: string) => state.users.find((user) => user.id === userId)
},
},
```
Cache within parameterized getters:
```ts
getters: {
getActiveUserById(state) {
const activeUsers = state.users.filter((user) => user.active)
return (userId: string) => activeUsers.find((user) => user.id === userId)
},
},
```
### Accessing Other Stores in Getters
```ts
import { useOtherStore } from './other-store'
getters: {
combined(state) {
const otherStore = useOtherStore()
return state.localData + otherStore.data
},
},
```
---
## Actions
Actions are methods for business logic. Unlike getters, they can be asynchronous.
### Defining Actions
```ts
actions: {
increment() {
this.count++
},
randomizeCounter() {
this.count = Math.round(100 * Math.random())
},
},
```
### Async Actions
```ts
actions: {
async registerUser(login: string, password: string) {
try {
this.userData = await api.post({ login, password })
} catch (error) {
return error
}
},
},
```
### Accessing Other Stores in Actions
```ts
import { useAuthStore } from './auth-store'
actions: {
async fetchUserPreferences() {
const auth = useAuthStore()
if (auth.isAuthenticated) {
this.preferences = await fetchPreferences()
}
},
},
```
**SSR:** Call all `useStore()` before any `await`:
```ts
async orderCart() {
// ✅ Call stores before await
const user = useUserStore()
await apiOrderCart(user.token, this.items)
// ❌ Don't call useStore() after await in SSR
}
```
### Subscribing to Actions
```ts
const unsubscribe = someStore.$onAction(
({ name, store, args, after, onError }) => {
const startTime = Date.now()
console.log(`Start "${name}" with params [${args.join(', ')}]`)
after((result) => {
console.log(`Finished "${name}" after ${Date.now() - startTime}ms`)
})
onError((error) => {
console.warn(`Failed "${name}": ${error}`)
})
}
)
unsubscribe() // Cleanup
```
Keep subscription after component unmount:
```ts
someStore.$onAction(callback, true)
```
---
## Options API Helpers
```ts
import { mapState, mapWritableState, mapActions } from 'pinia'
import { useCounterStore } from '../stores/counter'
export default {
computed: {
// Readonly state/getters
...mapState(useCounterStore, ['count', 'doubleCount']),
// Writable state
...mapWritableState(useCounterStore, ['count']),
},
methods: {
...mapActions(useCounterStore, ['increment']),
},
}
```
---
## Accessing Global Providers in Setup Stores
```ts
import { inject } from 'vue'
import { useRoute } from 'vue-router'
import { defineStore } from 'pinia'
export const useSearchFilters = defineStore('search-filters', () => {
const route = useRoute()
const appProvided = inject('appProvided')
// Don't return these - access them directly in components
return { /* ... */ }
})
```

name: composables-in-stores
description: Using Vue composables within Pinia stores
---
# Composables in Stores
Pinia stores can leverage Vue composables for reusable stateful logic.
## Option Stores
Call composables inside the `state` property, but only those returning writable refs:
```ts
import { defineStore } from 'pinia'
import { useLocalStorage } from '@vueuse/core'
export const useAuthStore = defineStore('auth', {
state: () => ({
user: useLocalStorage('pinia/auth/login', 'bob'),
}),
})
```
**Works:** Composables returning `ref()`:
- `useLocalStorage`
- `useAsyncState`
**Doesn't work in Option Stores:**
- Composables exposing functions
- Composables exposing readonly data
## Setup Stores
More flexible - can use almost any composable:
```ts
import { defineStore } from 'pinia'
import { useMediaControls } from '@vueuse/core'
import { ref } from 'vue'
export const useVideoPlayer = defineStore('video', () => {
const videoElement = ref<HTMLVideoElement>()
const src = ref('/data/video.mp4')
const { playing, volume, currentTime, togglePictureInPicture } =
useMediaControls(videoElement, { src })
function loadVideo(element: HTMLVideoElement, newSrc: string) {
videoElement.value = element
src.value = newSrc
}
return {
src,
playing,
volume,
currentTime,
loadVideo,
togglePictureInPicture,
}
})
```
**Note:** Don't return non-serializable DOM refs like `videoElement` - they're internal implementation details.
## SSR Considerations
### Option Stores with hydrate()
Define a `hydrate()` function to handle client-side hydration:
```ts
import { defineStore } from 'pinia'
import { useLocalStorage } from '@vueuse/core'
export const useAuthStore = defineStore('auth', {
state: () => ({
user: useLocalStorage('pinia/auth/login', 'bob'),
}),
hydrate(state, initialState) {
// Ignore server state, read from browser
state.user = useLocalStorage('pinia/auth/login', 'bob')
},
})
```
### Setup Stores with skipHydrate()
Mark state that shouldn't hydrate from server:
```ts
import { defineStore, skipHydrate } from 'pinia'
import { useEyeDropper, useLocalStorage } from '@vueuse/core'
export const useColorStore = defineStore('colors', () => {
const { isSupported, open, sRGBHex } = useEyeDropper()
const lastColor = useLocalStorage('lastColor', sRGBHex)
return {
// Skip hydration for client-only state
lastColor: skipHydrate(lastColor),
open, // Function - no hydration needed
isSupported, // Boolean - not reactive
}
})
```
`skipHydrate()` only applies to state properties (refs), not functions or non-reactive values.

# Composing Stores
Stores can use each other for shared state and logic.
## Rule: Avoid Circular Dependencies
Two stores cannot directly read each other's state during setup:
```ts
// ❌ Infinite loop
const useX = defineStore('x', () => {
const y = useY()
y.name // Don't read here!
return { name: ref('X') }
})
const useY = defineStore('y', () => {
const x = useX()
x.name // Don't read here!
return { name: ref('Y') }
})
```
**Solution:** Read in getters, computed, or actions:
```ts
const useX = defineStore('x', () => {
const y = useY()
// ✅ Read in computed/actions
function doSomething() {
const yName = y.name
}
return { name: ref('X'), doSomething }
})
```
## Setup Stores: Use Store at Top
```ts
import { defineStore } from 'pinia'
import { useUserStore } from './user'
export const useCartStore = defineStore('cart', () => {
const user = useUserStore()
const list = ref([])
const summary = computed(() => {
return `Hi ${user.name}, you have ${list.value.length} items`
})
function purchase() {
return apiPurchase(user.id, list.value)
}
return { list, summary, purchase }
})
```
## Shared Getters
Call `useStore()` inside a getter:
```ts
import { useUserStore } from './user'
export const useCartStore = defineStore('cart', {
getters: {
summary(state) {
const user = useUserStore()
return `Hi ${user.name}, you have ${state.list.length} items`
},
},
})
```
## Shared Actions
Call `useStore()` inside an action:
```ts
import { useUserStore } from './user'
import { apiOrderCart } from './api'
export const useCartStore = defineStore('cart', {
actions: {
async orderCart() {
const user = useUserStore()
try {
await apiOrderCart(user.token, this.items)
this.emptyCart()
} catch (err) {
displayError(err)
}
},
},
})
```
## SSR: Call Stores Before Await
In async actions, call all stores before any `await`:
```ts
actions: {
async orderCart() {
// ✅ All useStore() calls before await
const user = useUserStore()
const analytics = useAnalyticsStore()
try {
await apiOrderCart(user.token, this.items)
// ❌ Don't call useStore() after await (SSR issue)
// const otherStore = useOtherStore()
} catch (err) {
displayError(err)
}
},
}
```
This ensures the correct Pinia instance is used during SSR.

name: plugins
description: Extend stores with custom properties, methods, and behavior
---
# Plugins
Plugins extend all stores with custom properties, methods, or behavior.
## Basic Plugin
```ts
import { createPinia } from 'pinia'
function SecretPiniaPlugin() {
return { secret: 'the cake is a lie' }
}
const pinia = createPinia()
pinia.use(SecretPiniaPlugin)
// In any store
const store = useStore()
store.secret // 'the cake is a lie'
```
## Plugin Context
Plugins receive a context object:
```ts
import { PiniaPluginContext } from 'pinia'
export function myPiniaPlugin(context: PiniaPluginContext) {
context.pinia // pinia instance
context.app // Vue app instance
context.store // store being augmented
context.options // store definition options
}
```
## Adding Properties
Return an object to add properties (tracked in devtools):
```ts
pinia.use(() => ({ hello: 'world' }))
```
Or set directly on store:
```ts
pinia.use(({ store }) => {
store.hello = 'world'
// For devtools visibility in dev mode
if (process.env.NODE_ENV === 'development') {
store._customProperties.add('hello')
}
})
```
## Adding State
Add to both `store` and `store.$state` for SSR/devtools:
```ts
import { toRef, ref } from 'vue'
pinia.use(({ store }) => {
if (!store.$state.hasOwnProperty('hasError')) {
const hasError = ref(false)
store.$state.hasError = hasError
}
store.hasError = toRef(store.$state, 'hasError')
})
```
## Adding External Properties
Wrap non-reactive objects with `markRaw()`:
```ts
import { markRaw } from 'vue'
import { router } from './router'
pinia.use(({ store }) => {
store.router = markRaw(router)
})
```
## Custom Store Options
Define custom options consumed by plugins:
```ts
// Store definition
defineStore('search', {
actions: {
searchContacts() { /* ... */ },
},
debounce: {
searchContacts: 300,
},
})
// Plugin reads custom option
import debounce from 'lodash/debounce'
pinia.use(({ options, store }) => {
if (options.debounce) {
return Object.keys(options.debounce).reduce((acc, action) => {
acc[action] = debounce(store[action], options.debounce[action])
return acc
}, {})
}
})
```
For Setup Stores, pass options as third argument:
```ts
defineStore(
'search',
() => { /* ... */ },
{
debounce: { searchContacts: 300 },
}
)
```
## TypeScript Augmentation
### Custom Properties
```ts
import 'pinia'
import type { Router } from 'vue-router'
declare module 'pinia' {
export interface PiniaCustomProperties {
router: Router
hello: string
}
}
```
### Custom State
```ts
declare module 'pinia' {
export interface PiniaCustomStateProperties<S> {
hasError: boolean
}
}
```
### Custom Options
```ts
declare module 'pinia' {
export interface DefineStoreOptionsBase<S, Store> {
debounce?: Partial<Record<keyof StoreActions<Store>, number>>
}
}
```
## Subscribe in Plugins
```ts
pinia.use(({ store }) => {
store.$subscribe(() => {
// React to state changes
})
store.$onAction(() => {
// React to actions
})
})
```
## Nuxt Plugin
Create a Nuxt plugin to add Pinia plugins:
```ts
// plugins/myPiniaPlugin.ts
import { PiniaPluginContext } from 'pinia'
function MyPiniaPlugin({ store }: PiniaPluginContext) {
store.$subscribe((mutation) => {
console.log(`[🍍 ${mutation.storeId}]: ${mutation.type}`)
})
return { creationTime: new Date() }
}
export default defineNuxtPlugin(({ $pinia }) => {
$pinia.use(MyPiniaPlugin)
})
```

## Key Concepts
### Condition Compilation
Use special comments to write platform-specific code:
```vue
<!-- #ifdef APP-PLUS -->
<view>App only</view>
<!-- #endif -->
<!-- #ifdef MP-WEIXIN -->
<view>WeChat only</view>
<!-- #endif -->
```
### API Promise Support
Most uni-app APIs support Promise when no callback is provided:
```javascript
const res = await uni.request({ url: 'https://api.example.com' })
```
### Cross-Platform Best Practices
1. Use uni-app components and APIs instead of platform-specific ones
2. Use condition compilation for platform-specific features
3. Test on all target platforms
4. Use rpx for responsive layouts
5. Handle platform differences in manifest.json
6. must use uni-helper tools
### MCP扩展
当需要查询 uni-app 官方文档时,优先调用 `search-docs-by-Uniapp-official` MCP 工具搜索相关 API 文档和使用示例。
**使用场景:**
- 用户询问特定 API 的详细用法
- 需要官方文档中的代码示例
- 查询组件的属性和事件
- 了解 API 的平台兼容性
**工具安装:**
如果检测到该 MCP 工具不可用,引导用户访问 https://github.com/uni-helper/mcp 进行安装。

# UniApp Core Framework
UniApp is a Vue.js-based cross-platform framework for developing applications that run on iOS, Android, HarmonyOS, Web, and various mini-program platforms (WeChat, Alipay, Baidu, Douyin, etc.).
## Project Structure
```
project-root/
├── pages/ # Page files
│ └── index/
│ └── index.vue # Page component
├── components/ # Reusable components
├── static/ # Static assets (images, fonts)
├── App.vue # Application root component
├── main.js # Application entry
├── manifest.json # App configuration
├── pages.json # Page routing config
└── uni.scss # Global SCSS variables
```
## Platform Support
| Platform | Value | Description |
|----------|-------|-------------|
| App | APP-PLUS | iOS/Android native apps |
| App nvue | APP-PLUS-NVUE | Native rendering pages |
| H5 | H5 / WEB | Web applications |
| WeChat Mini Program | MP-WEIXIN | WeChat MP |
| Alipay | MP-ALIPAY | Alipay MP |
| Baidu | MP-BAIDU | Baidu Smart Program |
| Douyin | MP-TOUTIAO | ByteDance MP |
| QQ | MP-QQ | QQ Mini Program |
| Kuaishou | MP-KUAISHOU | Kuaishou MP |
| HarmonyOS | APP-HARMONY | HarmonyOS Next |
## Condition Compilation
Handle platform differences using special comment syntax:
```vue
<template>
<view>
<!-- #ifdef APP-PLUS -->
<text>App only content</text>
<!-- #endif -->
<!-- #ifdef MP-WEIXIN -->
<text>WeChat MP only</text>
<!-- #endif -->
<!-- #ifndef H5 -->
<text>All platforms except H5</text>
<!-- #endif -->
</view>
</template>
<script>
export default {
methods: {
getPlatform() {
// #ifdef APP-PLUS
return 'App'
// #endif
// #ifdef H5
return 'Web'
// #endif
}
}
}
</script>
<style>
/* #ifdef APP-PLUS */
.app-style { padding: 20px; }
/* #endif */
</style>
```
## Platform Values Reference
| Value | Description |
|-------|-------------|
| VUE3 / VUE2 | Vue version |
| UNI-APP-X | UniApp X project |
| APP-PLUS | App (JS engine) |
| APP-PLUS-NVUE / APP-NVUE | App nvue pages |
| APP-ANDROID | Android platform |
| APP-IOS | iOS platform |
| APP-HARMONY | HarmonyOS Next |
| H5 / WEB | Web platform |
| MP-WEIXIN | WeChat Mini Program |
| MP-ALIPAY | Alipay Mini Program |
| MP-BAIDU | Baidu Smart Program |
| MP-TOUTIAO | Douyin Mini Program |
| MP-LARK | Feishu Mini Program |
| MP-QQ | QQ Mini Program |
| MP-KUAISHOU | Kuaishou Mini Program |
| MP-HARMONY | HarmonyOS Meta Service |
## API Promise Support
UniApp APIs support Promise when no callback is provided:
```javascript
// Promise style
uni.request({ url: 'https://api.example.com' })
.then(res => console.log(res))
.catch(err => console.error(err))
// Async/await
async function fetchData() {
try {
const res = await uni.request({ url: 'https://api.example.com' })
return res.data
} catch (err) {
console.error(err)
}
}
```
**Note:** Synchronous APIs (ending in `Sync`), `create*` methods, and `*Manager` methods do not support Promise.

// DOM mounted
// Good for DOM operations
},
// === Updating ===
beforeUpdate() {
// Before data update
},
updated() {
// After data update
},
// === Destruction ===
beforeDestroy() {
// Before instance destroyed
// Clean up here
},
destroyed() {
// Instance destroyed
},
// === Keep-alive ===
activated() {
// Component activated (kept-alive)
},
deactivated() {
// Component deactivated (kept-alive)
}
}
</script>
```
## Component Lifecycle (Vue 3)
```vue
<script setup>
import {
onBeforeMount,
onMounted,
onBeforeUpdate,
onUpdated,
onBeforeUnmount,
onUnmounted,
onActivated,
onDeactivated
} from 'vue'
// Setup runs before beforeCreate
console.log('setup')
onBeforeMount(() => {
console.log('onBeforeMount')
})
onMounted(() => {
console.log('onMounted')
})
onBeforeUpdate(() => {
console.log('onBeforeUpdate')
})
onUpdated(() => {
console.log('onUpdated')
})
onBeforeUnmount(() => {
console.log('onBeforeUnmount')
})
onUnmounted(() => {
console.log('onUnmounted')
})
onActivated(() => {
console.log('onActivated')
})
onDeactivated(() => {
console.log('onDeactivated')
})
</script>
```
## Lifecycle Comparison
| Scenario | UniApp Page | Vue Component |
|----------|-------------|---------------|
| Initial load | onLoad | created |
| DOM ready | onReady | mounted |
| Page show | onShow | - |
| Page hide | onHide | - |
| Page destroy | onUnload | destroyed/unmounted |
| Data refresh | onPullDownRefresh | - |
| Infinite scroll | onReachBottom | - |
| Scroll position | onPageScroll | - |
## App Update Manager
```javascript
// In App.vue onLaunch
onLaunch() {
const updateManager = uni.getUpdateManager()
updateManager.onCheckForUpdate((res) => {
console.log('Has update:', res.hasUpdate)
})
updateManager.onUpdateReady(() => {
uni.showModal({
title: 'Update Ready',
content: 'New version downloaded. Restart to apply?',
success: (res) => {
if (res.confirm) {
updateManager.applyUpdate()
}
}
})
})
updateManager.onUpdateFailed(() => {
console.error('Update failed')
})
}
```
## Best Practices
### Data Loading Pattern
```javascript
export default {
data() {
return {
loading: false,
error: null,
data: null
}
},
onLoad(options) {
this.fetchData(options.id)
},
onPullDownRefresh() {
this.fetchData(this.id).finally(() => {
uni.stopPullDownRefresh()
})
},
methods: {
async fetchData(id) {
this.loading = true
this.error = null
try {
this.data = await api.getDetail(id)
} catch (err) {
this.error = err.message
} finally {
this.loading = false
}
}
}
}
```
### Scroll Performance
```javascript
export default {
data() {
return {
scrollTop: 0,
showBackTop: false
}
},
// Throttle scroll events
onPageScroll: throttle(function(e) {
this.scrollTop = e.scrollTop
this.showBackTop = e.scrollTop > 500
}, 200),
methods: {
scrollToTop() {
uni.pageScrollTo({
scrollTop: 0,
duration: 300
})
}
}
}
```

onReady() {
this.mapContext = uni.createMapContext('myMap')
},
methods: {
// Get center location
getCenter() {
this.mapContext.getCenterLocation({
success: (res) => {
console.log('Center:', res.latitude, res.longitude)
}
})
},
// Move to location
moveToLocation() {

longitude: 116.4
})
},
// Translate marker
translateMarker() {
this.mapContext.translateMarker({
markerId: 1,
destination: {
latitude: 39.91,
longitude: 116.41
},
autoRotate: true,
rotate: 0,
duration: 1000
})
},
// Include points in view
includePoints() {
this.mapContext.includePoints({
points: [
{ latitude: 39.9, longitude: 116.4 },
{ latitude: 39.91, longitude: 116.41 }
],
padding: [10, 10, 10, 10]
})
},
// Get region
getRegion() {
this.mapContext.getRegion({
success: (res) => {
console.log('Southwest:', res.southwest)
console.log('Northeast:', res.northeast)
}
})
},
// Add markers
addMarkers() {
this.mapContext.addMarkers({
markers: [{
id: 2,
latitude: 39.91,
longitude: 116.41,
title: 'New Marker'
}],
clear: false // Don't clear existing

```
## Coordinate Systems
| System | Description | Usage |
|--------|-------------|-------|
| WGS84 | GPS coordinates | International standard |
| GCJ02 | Mars coordinates | China national standard |
| BD09 | Baidu coordinates | Baidu Map only |
**Note:** For map display in China, use `gcj02`.
## Permission Configuration
### Mini-Program
Add to `manifest.json`:
```json
{
"mp-weixin": {
"permission": {
"scope.userLocation": {
"desc": "Your location is needed to find nearby stores"
}
},
"requiredPrivateInfos": [
"getLocation",
"chooseLocation"
]
}
}
```
### App (Android)
```json
{
"app-plus": {
"distribute": {
"android": {
"permissions": [
"<uses-permission android:name=\"android.permission.ACCESS_FINE_LOCATION\" />",
"<uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />"
]
}
}
}
}
```
### App (iOS)
```json
{
"app-plus": {
"distribute": {
"ios": {
"privacyDescription": {
"NSLocationWhenInUseUsageDescription": "Location is needed to find nearby stores",
"NSLocationAlwaysUsageDescription": "Background location is needed for navigation"
}
}
}
}
}
```
## Best Practices
### Permission Handling
```javascript
async function getLocationWithPermission() {
try {
// Check permission
const setting = await uni.getSetting()
if (!setting.authSetting['scope.userLocation']) {
// Request permission
await uni.authorize({ scope: 'scope.userLocation' })
}
// Get location
const res = await uni.getLocation({ type: 'gcj02' })
return res
} catch (err) {
if (err.errMsg.includes('auth deny')) {
uni.showModal({
title: 'Permission Required',
content: 'Please enable location permission in settings',
success: (res) => {
if (res.confirm) {
uni.openSetting()
}
}
})
}
throw err
}
}
```
### Distance Calculation
```javascript
function calculateDistance(lat1, lon1, lat2, lon2) {
const R = 6371 // Earth's radius in km
const dLat = (lat2 - lat1) * Math.PI / 180
const dLon = (lon2 - lon1) * Math.PI / 180
const a = Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(lat1 * Math.PI / 180) * Math.cos(lat2 * Math.PI / 180) *
Math.sin(dLon/2) * Math.sin(dLon/2)
const c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a))
return R * c // Distance in km
}
```

},
success: () => {
console.log('WebSocket connecting...')
}
})
// Listen for connection open
uni.onSocketOpen((res) => {
console.log('WebSocket connected')
// Send message
uni.sendSocketMessage({
data: JSON.stringify({
type: 'message',
content: 'Hello server'
})
})
})
// Listen for messages
uni.onSocketMessage((res) => {
console.log('Received:', res.data)
const data = JSON.parse(res.data)
// Handle message...
})
// Listen for errors
uni.onSocketError((err) => {
console.error('WebSocket error:', err)
})
// Listen for close
uni.onSocketClose((res) => {
console.log('WebSocket closed:', res)
})

## Request Interceptors
Use `uni.addInterceptor` to intercept requests.
```javascript
// Add request interceptor
uni.addInterceptor('request', {
invoke(args) {
// Before request
console.log('Request:', args)
// Add auth token
args.header = args.header || {}
args.header.Authorization = `Bearer ${getToken()}`
return args
},
success(res) {
// After success
console.log('Response:', res)
return res
},
fail(err) {
// After failure
console.error('Request failed:', err)
return err
},
complete(res) {
// Always executed
console.log('Request complete')
}
})
// Remove interceptor
uni.removeInterceptor('request')
```
## Domain Configuration
### Mini-Program
Configure request domains in mini-program developer console:
- `request` domain: For `uni.request`
- `uploadFile` domain: For `uni.uploadFile`
- `downloadFile` domain: For `uni.downloadFile`
- `websocket` domain: For `uni.connectSocket`
### H5
H5 uses browser's same-origin policy. Configure CORS on server or use proxy in development.
```javascript
// vite.config.js proxy configuration
export default {
server: {
proxy: {
'/api': {
target: 'https://api.example.com',
changeOrigin: true,
rewrite: (path) => path.replace(/^\/api/, '')
}
}
}
}
```
## Best Practices
```javascript
// Create a request wrapper
const request = (options) => {
return new Promise((resolve, reject) => {
uni.request({
...options,
success: (res) => {
if (res.statusCode >= 200 && res.statusCode < 300) {
resolve(res.data)
} else if (res.statusCode === 401) {
// Handle unauthorized
uni.redirectTo({ url: '/pages/login/login' })
reject(new Error('Unauthorized'))
} else {
reject(new Error(res.data.message || 'Request failed'))
}
},
fail: reject
})
})
}
// Usage
const api = {
getUser: () => request({ url: '/user' }),
updateUser: (data) => request({ url: '/user', method: 'PUT', data })
}
```

# Storage
## Synchronous Storage (Recommended for small data)
### uni.setStorageSync
Store data synchronously.
```javascript
// Store simple value
uni.setStorageSync('username', 'John')
// Store object
uni.setStorageSync('userInfo', {
name: 'John',
age: 30,
email: 'john@example.com'
})
// Store array
uni.setStorageSync('tags', ['vue', 'uniapp', 'javascript'])
```
### uni.getStorageSync
Retrieve data synchronously.
```javascript
// Get simple value
const username = uni.getStorageSync('username')
console.log(username) // 'John'
// Get object
const userInfo = uni.getStorageSync('userInfo')
console.log(userInfo.name) // 'John'
// Check if exists
const value = uni.getStorageSync('nonexistent')
console.log(value) // '' (empty string if not found)
```
### uni.removeStorageSync
Remove specific key.
```javascript
uni.removeStorageSync('username')
```
### uni.clearStorageSync
Clear all storage.
```javascript
uni.clearStorageSync()
```
## Asynchronous Storage (Recommended for large data)
### uni.setStorage
```javascript
uni.setStorage({
key: 'userData',
data: {
id: 123,
preferences: { theme: 'dark', language: 'zh' }
},
success: () => {
console.log('Storage saved')
},
fail: (err) => {
console.error('Save failed:', err)
}
})
// Promise style
uni.setStorage({
key: 'config',
data: { debug: true }
}).then(() => {
console.log('Config saved')
})
```
### uni.getStorage
```javascript
uni.getStorage({
key: 'userData',
success: (res) => {
console.log('Data:', res.data)
},
fail: (err) => {
console.log('Key not found')
}
})
// Promise style
uni.getStorage({ key: 'userData' })
.then(res => console.log(res.data))
.catch(() => console.log('Not found'))
```
### uni.removeStorage
```javascript
uni.removeStorage({
key: 'tempData',
success: () => {
console.log('Removed successfully')
}
})
```
### uni.getStorageInfo
Get storage information.
```javascript
uni.getStorageInfo({
success: (res) => {
console.log('Keys:', res.keys)
console.log('Current size:', res.currentSize, 'KB')
console.log('Limit size:', res.limitSize, 'KB')
}
})
```
## Storage Limits
| Platform | Limit |
|----------|-------|
| Mini Program | 10 MB (single) / 200+ MB total |
| App | No hard limit (device dependent) |
| H5 | ~5-10 MB (browser dependent) |
## Best Practices
### Data Persistence Helper
```javascript
const storage = {
// Set with expiration (days)
setWithExpiry(key, value, days) {
const item = {
value,
expiry: Date.now() + days * 24 * 60 * 60 * 1000
}
uni.setStorageSync(key, item)
},
// Get with expiration check
getWithExpiry(key) {
const item = uni.getStorageSync(key)
if (!item) return null
if (Date.now() > item.expiry) {
uni.removeStorageSync(key)
return null
}
return item.value
},
// Safe get with default
get(key, defaultValue = null) {
try {
const value = uni.getStorageSync(key)
return value !== '' ? value : defaultValue
} catch (e) {
return defaultValue
}
},
// Batch operations
setBatch(data) {
Object.entries(data).forEach(([key, value]) => {
uni.setStorageSync(key, value)
})
},
clear() {
uni.clearStorageSync()
}
}
// Usage
storage.setWithExpiry('token', 'abc123', 7) // Expires in 7 days
const token = storage.getWithExpiry('token')
```
### User Session Management
```javascript
const session = {
setToken(token) {
uni.setStorageSync('access_token', token)
},
getToken() {
return uni.getStorageSync('access_token')
},
clearToken() {
uni.removeStorageSync('access_token')
},
setUserInfo(info) {
uni.setStorageSync('user_info', info)
},
getUserInfo() {
return uni.getStorageSync('user_info')
},
isLoggedIn() {
return !!this.getToken()
},
clear() {
this.clearToken()
uni.removeStorageSync('user_info')
}
}
```
## File Storage (App only)
### Local File System
```javascript
// Get file system manager
const fs = uni.getFileSystemManager()
// Write file
fs.writeFile({
filePath: `${uni.env.USER_DATA_PATH}/data.json`,
data: JSON.stringify({ name: 'test' }),
encoding: 'utf8',
success: () => console.log('File written')
})
// Read file
fs.readFile({
filePath: `${uni.env.USER_DATA_PATH}/data.json`,
encoding: 'utf8',
success: (res) => {
const data = JSON.parse(res.data)
console.log(data)
}
})
// Check if file exists
fs.access({
path: `${uni.env.USER_DATA_PATH}/data.json`,
success: () => console.log('File exists'),
fail: () => console.log('File not found')
})
```
## Storage Comparison
| Method | Data Type | Size Limit | Async | Use Case |
|--------|-----------|------------|-------|----------|
| StorageSync | Any | ~10MB | No | Small config data |
| Storage | Any | ~10MB | Yes | Large data objects |
| File System | Binary/Text | Large | Yes | Files, images |

uni.showTabBar({
animation: true
})
```
### Set Tab Bar Style
```javascript
uni.setTabBarStyle({
color: '#999',
selectedColor: '#007AFF',
backgroundColor: '#fff',
borderStyle: 'black'
})
```
### Set Tab Bar Item
```javascript
uni.setTabBarItem({
index: 0,
text: 'Home',
iconPath: '/static/home.png',
selectedIconPath: '/static/home-active.png'
})
```
### Add/Remove Tab Bar Badge
```javascript
// Show badge
uni.showTabBarRedDot({
index: 2 // Tab index
})
// Hide badge
uni.hideTabBarRedDot({
index: 2
})
// Set badge text
uni.setTabBarBadge({
index: 2,
text: '5'
})
// Remove badge text
uni.removeTabBarBadge({
index: 2
})
```
## Preview Image
```javascript
uni.previewImage({
current: 'https://example.com/1.jpg', // Current image
urls: [
'https://example.com/1.jpg',
'https://example.com/2.jpg',
'https://example.com/3.jpg'
],
indicator: 'default', // default/number/none
loop: false,
longPressActions: {
itemList: ['Save Image', 'Share'],
success: (data) => {
console.log('Long press:', data.tapIndex)
}
}
})
```
## Save Image to Photos
```javascript
uni.saveImageToPhotosAlbum({
filePath: 'temp://path/to/image.jpg',
success: () => {
uni.showToast({ title: 'Saved' })
}
})
```
## Best Practices
### Toast Helper
```javascript
const toast = {
success(message, duration = 2000) {
uni.showToast({ title: message, icon: 'success', duration })
},
error(message, duration = 2000) {
uni.showToast({ title: message, icon: 'error', duration })
},
loading(message = 'Loading...') {
uni.showLoading({ title: message, mask: true })
},
hide() {
uni.hideLoading()
uni.hideToast()
},
text(message, duration = 2000) {
uni.showToast({ title: message, icon: 'none', duration })
}
}
// Usage
toast.loading()
fetchData()
.then(() => toast.success('Loaded'))
.catch(() => toast.error('Failed'))
.finally(() => toast.hide())
```
### Modal Helper
```javascript
const modal = {
confirm(title, content) {
return new Promise((resolve) => {
uni.showModal({
title,
content,
success: (res) => resolve(res.confirm)
})
})
},
alert(title, content) {
return new Promise((resolve) => {
uni.showModal({
title,
content,
showCancel: false,
success: () => resolve()
})
})
},
action(items) {
return new Promise((resolve, reject) => {
uni.showActionSheet({
itemList: items,
success: (res) => resolve(res.tapIndex),
fail: reject
})
})
}
}
// Usage
async function deleteItem(id) {
const confirmed = await modal.confirm('Delete', 'Are you sure?')
if (confirmed) {
await api.delete(id)
toast.success('Deleted')
}
}
```

name: uni-network
description: Promise-based HTTP client for uni-app - axios-inspired API with uni.request as default transport
---
# uni-network
Promise-based HTTP client for uni-app, inspired by axios@0.27.2. Uses uni.request/uni.uploadFile/uni.downloadFile as the underlying transport.
## Installation
```bash
npm i @uni-helper/uni-network
```
## Features
- Promise-based API
- Request/response interceptors
- Request cancellation
- TypeScript support
- Composition API integration
- Upload/download support
## Basic Usage
```ts
import { un } from '@uni-helper/uni-network'
// GET request
un('/user/123')
// POST request
un({
method: 'POST',
url: '/user/123',
data: {
firstName: 'Fred',
lastName: 'Flintstone',
},
})
```
## Request Aliases
```ts
import { un } from '@uni-helper/uni-network'
// HTTP verbs
un.get('/users')
un.post('/users', { name: 'John' })
un.put('/users/1', { name: 'Jane' })
un.patch('/users/1', { age: 30 })
un.delete('/users/1')
// Upload/download
un.upload({
url: '/upload',
filePath: tempFilePath,
name: 'file',
})
un.download({
url: '/files/report.pdf',
})
```
## Creating an Instance
```ts
import { createUniNetwork } from '@uni-helper/uni-network'
const http = createUniNetwork({
baseURL: 'https://api.example.com',
timeout: 10000,
headers: {
'Content-Type': 'application/json',
},
})
// Use the instance
http.get('/users')
```
## Interceptors
```ts
import { un } from '@uni-helper/uni-network'
// Request interceptor
un.interceptors.request.use(
(config) => {
// Add auth token
const token = uni.getStorageSync('token')
if (token) {
config.headers = config.headers || {}
config.headers.Authorization = `Bearer ${token}`
}
return config
},
(error) => {
return Promise.reject(error)
}
)
// Response interceptor
un.interceptors.response.use(
(response) => {
// Transform response data
return response.data
},
(error) => {
// Handle errors globally
if (error.statusCode === 401) {
uni.redirectTo({ url: '/pages/login/index' })
}
return Promise.reject(error)
}
)
```
## Configuration
```ts
interface UniNetworkConfig {
// URL
url?: string
// Base URL
baseURL?: string
// Method
method?: 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH' | ...
// Headers
headers?: Record<string, string>
// Request data
data?: any
// Query params
params?: Record<string, any>
// Timeout in ms
timeout?: number
// Response type
responseType?: 'text' | 'arraybuffer'
// Data type
dataType?: 'json' | 'string'
// Enable http2
enableHttp2?: boolean
// Enable quic
enableQuic?: boolean
// Enable cache
enableCache?: boolean
// SSL verify
sslVerify?: boolean
}
```
## Request Cancellation
```ts
import { un } from '@uni-helper/uni-network'
const controller = new AbortController()
un.get('/long-request', {
signal: controller.signal,
})
// Cancel after 5 seconds
setTimeout(() => {
controller.abort()
}, 5000)
```
## Error Handling
```ts
import { un, UniNetworkError } from '@uni-helper/uni-network'
try {
const response = await un.get('/users')
} catch (error) {
if (error instanceof UniNetworkError) {
console.log('Request failed:', error.message)
console.log('Status:', error.statusCode)
}
}
```
## Composition API
```ts
import { useUniNetwork } from '@uni-helper/uni-network'
const { data, error, loading, execute } = useUniNetwork({
url: '/users',
method: 'GET',
})
// Execute manually
await execute()
```
## TypeScript Support
```ts
import { un } from '@uni-helper/uni-network'
interface User {
id: number
name: string
email: string
}
// Typed response
const { data } = await un.get<User>('/users/1')
console.log(data.name) // Type-safe access
```

name: uni-promises
description: Promise wrappers for uni-app APIs - convert callback-based APIs to Promise-based
---
# uni-promises
Promise wrappers for uni-app's callback-based APIs. Convert uni-app APIs to return Promises for better async/await support.
## Installation
```bash
npm i @uni-helper/uni-promises
```
## Usage
Instead of using callbacks:
```ts
// Original callback style
uni.request({
url: 'https://api.example.com',
success: (res) => {
console.log(res.data)
},
fail: (err) => {
console.error(err)
},
})
```
Use Promises:
```ts
import { request } from '@uni-helper/uni-promises'
// Promise style
const res = await request({
url: 'https://api.example.com',
})
console.log(res.data)
```
## Available APIs

})
// Navigate
await navigateTo({
url: '/pages/success/index',
})
} catch (error) {
await showToast({

name: uni-typed
description: TypeScript type definitions for uni-app templates - complete type safety for uni-app components
---
# uni-typed
TypeScript type definitions for uni-app template sections. Provides complete type safety and IntelliSense for uni-app components.
## Installation
```bash
# For uni-app
npm i -D @uni-helper/uni-app-types
# For uni-ui
npm i -D @uni-helper/uni-ui-types
# For uni-cloud
npm i -D @uni-helper/uni-cloud-types
```
## Setup
### Uni-app Types
```json
// tsconfig.json
{
"compilerOptions": {
"types": ["@uni-helper/uni-app-types"]
}
}
```
### Uni-ui Types
```json
// tsconfig.json
{
"compilerOptions": {
"types": [
"@uni-helper/uni-app-types",
"@uni-helper/uni-ui-types"
]
}
}
```
## Features
- Type-safe template event handlers
- Component prop type checking
- Custom event type definitions
- Ref type inference for components
## Component Types
### Template Type Safety
```vue
<script setup lang="ts">
import { ref } from 'vue'
const inputValue = ref('')
const count = ref(0)
const handleInput = (e: UniHelper.InputOnInputEvent) => {
inputValue.value = e.detail.value
}
const handleChange = (e: UniHelper.SwitchOnChangeEvent) => {
console.log(e.detail.value)
}
</script>
<template>
<!-- Type-safe component usage -->
<input
type="text"
:value="inputValue"
@input="handleInput"
/>
<switch :checked="true" @change="handleChange" />
</template>
```
### Component Ref Types
```vue
<script setup lang="ts">
import { ref, onMounted } from 'vue'
// Type-safe component refs
const videoRef = ref<UniHelper.VideoInstance>()
const mapRef = ref<UniHelper.MapInstance>()
onMounted(() => {
// IntelliSense for component methods
videoRef.value?.play()
videoRef.value?.pause()
videoRef.value?.seek(100)
mapRef.value?.moveToLocation({
latitude: 39.9,
longitude: 116.4,
})
})
</script>
<template>
<video ref="videoRef" src="..." />
<map ref="mapRef" />
</template>
```
## Event Types
### Common Event Types
```ts
// Input events
UniHelper.InputOnInputEvent
UniHelper.InputOnBlurEvent
UniHelper.InputOnFocusEvent
// Form events
UniHelper.SwitchOnChangeEvent
UniHelper.CheckboxOnChangeEvent
UniHelper.RadioOnChangeEvent
UniHelper.PickerOnChangeEvent
UniHelper.SliderOnChangeEvent
// Media events
UniHelper.VideoOnPlayEvent
UniHelper.VideoOnPauseEvent
UniHelper.VideoOnEndedEvent
UniHelper.VideoOnTimeUpdateEvent
// Touch events
UniHelper.ViewOnTouchstartEvent
UniHelper.ViewOnTouchmoveEvent
UniHelper.ViewOnTouchendEvent
UniHelper.ViewOnTapEvent
UniHelper.ViewOnLongpressEvent
// Scroll events
UniHelper.ScrollViewOnScrollEvent
UniHelper.ScrollViewOnScrolltolowerEvent
UniHelper.ScrollViewOnScrolltoupperEvent
```
### Custom Events
Define custom event types for your components:
```vue
<script setup lang="ts">
// Child component
const emit = defineEmits<{
change: [value: string]
submit: [data: { id: number; name: string }]
}>()
</script>
```
```vue
<script setup lang="ts">
// Parent component
import type { MyComponentOnChangeEvent } from './types'
const handleChange = (e: MyComponentOnChangeEvent) => {
console.log(e.detail.value)
}
</script>
<template>
<my-component @change="handleChange" />
</template>
```
## Why uni-typed?
DCloud's `@dcloudio/types` only provides TypeScript support for script sections. uni-typed fills the gap for template section type safety, providing:
- Component prop validation
- Event handler type checking
- Method IntelliSense on component refs
- Better IDE support (VS Code, WebStorm)
## Migration from v0 to v1
See the [migration guide](https://uni-helper.js.org/uni-typed/other/migrate-v0-to-v1) for upgrading instructions.

name: vite-plugin-uni-components
description: On-demand automatic component imports for uni-app - derived from unplugin-vue-components
---
# vite-plugin-uni-components
Automatic on-demand component imports for uni-app. Derived from unplugin-vue-components with uni-app specific adaptations.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-components
```
## Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import Components from '@uni-helper/vite-plugin-uni-components'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [
Components(), // Must be before Uni()
Uni(),
],
})
```
## Features
- Automatic component imports from `src/components`
- Supports UI library resolvers
- Generates TypeScript declarations
- Handles `default` export for third-party UI libraries
## Supported UI Libraries
Built-in resolvers for:
| Library | Import |
|---------|--------|
| Ano UI | `AnoUIResolver()` |
| uni-ui | `UniUIResolver()` |
| wot-design-uni | `WotDesignUniResolver()` |
| uv-uni | `UvUniResolver()` |
| uview-pro | `UviewProResolver()` |
| z-paging | `ZPagingResolver()` |
## TypeScript Declarations
For pnpm users, create `.npmrc`:
```ini
shamefully-hoist = true
```
Generated `components.d.ts` example:
```ts
declare module 'vue' {
export interface GlobalComponents {
AButton: typeof import('ano-ui/components/AButton/AButton.vue')['default']
UniCalendar: typeof import('@dcloudio/uni-ui/lib/uni-calendar/uni-calendar.vue')['default']
MyComponent: typeof import('./src/components/MyComponent.vue')['default']
}
}
```
## Third-Party Component Handling
For third-party components like `@dcloudio/uni-ui` and `ano-ui`, the plugin automatically adds the `default` property to handle H5 compatibility issues:
```diff
declare module 'vue' {
export interface GlobalComponents {
- AButton: typeof import('ano-ui/components/AButton/AButton.vue')['AButton']
+ AButton: typeof import('ano-ui/components/AButton/AButton.vue')['default']
}
}

# vite-plugin-uni-layouts
Provides a Nuxt-like layout system for uni-app. Wraps pages with reusable layout components.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-layouts
```
## Setup
```ts
// vite.config.ts
import uni from '@dcloudio/vite-plugin-uni'
import UniLayouts from '@uni-helper/vite-plugin-uni-layouts'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [UniLayouts(), uni()],
})
```
## Creating Layouts
Create layout files in `src/layouts/` directory:
```vue
<!-- src/layouts/default.vue -->
<template>
<view class="layout">
<slot name="header" />
<slot>main content</slot>
<slot name="footer" />
</view>
</template>
```
## Applying Layouts
### Via pages.json (traditional)
```json
{
"pages": [{
"path": "pages/index/index",
"layout": "default"
},
{
"path": "pages/about/index",
"layout": false // Disable layout
}]
}
```
### Via definePage (recommended)
```vue
<script setup>
definePage({
layout: 'default',
})
</script>
```
## Dynamic Layouts
Use the `<uni-layout>` component for dynamic layout switching:
```vue
<script setup>
const layoutName = ref('default')
</script>
<template>
<!-- Disable page layout first -->
<uni-layout :name="layoutName">
<template #header>
<text>Header content</text>
</template>
Main content here
<template #footer>
<text>Footer content</text>
</template>
</uni-layout>
</template>
```
### Accessing Layout Ref
```vue
<script setup>
const uniLayout = ref()
onMounted(() => {
console.log(uniLayout.value) // Access layout component
})
</script>
<template>
<uni-layout ref="uniLayout">
Content
</uni-layout>
</template>
```
Options API:
```vue
<script>
export default {
onLoad() {
console.log(this.$refs.uniLayout)
},
}
</script>
```
## How It Works
The plugin does two things:
1. Auto-scans and globally registers components from `layouts/` directory
2. Wraps pages with the specified layout component
> **Note:** WeChat Mini Program limitation - If using `web-view` component, layout wrapping may not work properly.
## Configuration
See [type definitions](https://github.com/uni-helper/vite-plugin-uni-layouts/blob/main/src/types.ts) for all options.

description: Write uni-app manifest.json in TypeScript with type safety and IntelliSense
---
# vite-plugin-uni-manifest
Write your uni-app `manifest.json` configuration in TypeScript with full type safety and IntelliSense support.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-manifest
```
## Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import UniManifest from '@uni-helper/vite-plugin-uni-manifest'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [UniManifest(), Uni()],
})
```
## Configuration File
Create `manifest.config.ts` (or .js/.json):
```ts
// manifest.config.ts
import { defineManifestConfig } from '@uni-helper/vite-plugin-uni-manifest'
export default defineManifestConfig({
name: 'my-uni-app',
appid: '__UNI__XXXXXXX',
description: 'My awesome uni-app project',
versionName: '1.0.0',
versionCode: '100',
transformPx: false,
app: {
// App-specific config
},
mp-weixin: {
// WeChat Mini Program config
},
mp-alipay: {
// Alipay Mini Program config
},
h5: {
// H5 config
},
})
```
## Benefits
- **Type Safety**: Full TypeScript intellisense for all manifest properties
- **Code Reuse**: Import and reuse configuration values
- **Comments**: Add comments to explain configuration choices
- **Environment-based Config**: Use conditionals for different environments
## Example with Dynamic Config
```ts
import { defineManifestConfig } from '@uni-helper/vite-plugin-uni-manifest'
import { version } from './package.json'
export default defineManifestConfig({
name: 'My App',
versionName: version,
versionCode: version.replace(/\./g, ''),
// Platform-specific config
'mp-weixin': {
appid: process.env.WX_APPID || '',
setting: {
es6: true,
enhance: true,
},
},
h5: {
title: 'My H5 App',
router: {
mode: 'hash',
},
},
})
```
## Configuration Options
See [types.ts](https://github.com/uni-helper/vite-plugin-uni-manifest/tree/main/packages/core/src/types.ts) for all available options.

name: vite-plugin-uni-middleware
description: Route middleware support for uni-app - implement guards, auth, and page lifecycle hooks
---
# vite-plugin-uni-middleware
Add Express-style middleware support to uni-app routing. Implement authentication guards, page analytics, and custom route logic.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-middleware
```
## Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import UniMiddleware from '@uni-helper/vite-plugin-uni-middleware'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [UniMiddleware(), Uni()],
})
```
## Creating Middleware
Create middleware files in `src/middleware/` directory:
```ts
// src/middleware/auth.ts
import { defineMiddleware } from '@uni-helper/vite-plugin-middleware'
export default defineMiddleware((to, from, next) => {
const token = uni.getStorageSync('token')
if (!token && to.path !== '/pages/login/index') {
// Redirect to login
next('/pages/login/index')
} else {
// Continue navigation
next()
}
})
```
```ts
// src/middleware/analytics.ts
export default defineMiddleware((to, from, next) => {
// Track page view
uni.report('page_view', {
path: to.path,
from: from.path,
timestamp: Date.now(),
})
next()
})
```
```ts
// src/middleware/logger.ts
export default defineMiddleware((to, from, next) => {
console.log(`[Router] ${from.path} -> ${to.path}`)
next()
})
```
## Applying Middleware
### Via definePage (recommended)
```vue
<script setup>
definePage({
middlewares: ['auth', 'analytics'],
})
</script>
```
### Via pages.json
```json
{
"pages": [{
"path": "pages/profile/index",
"middlewares": ["auth"]
}]
}
```
### Global Middleware
Create `src/middleware/index.ts` for global middleware:
```ts
// src/middleware/index.ts
export default defineMiddleware((to, from, next) => {
// Runs on every navigation
console.log('Global middleware')
next()
})
```
## Middleware Context
```ts
interface MiddlewareContext {
to: {
path: string
query: Record<string, string>
meta?: Record<string, any>
}
from: {
path: string
query: Record<string, string>
}
next: (path?: string) => void
}
```
## Middleware Order
Middleware executes in declaration order:
```vue
<script setup>
definePage({
// Runs: logger -> auth -> analytics
middlewares: ['logger', 'auth', 'analytics'],
})
</script>
```
## Navigation Control
```ts
export default defineMiddleware((to, from, next) => {
// Continue to route
next()
// Redirect to different route
next('/pages/other/index')
// Redirect with query
next({
path: '/pages/login/index',
query: { redirect: to.path },
})
// Cancel navigation (stay on current page)
next(false)
})
```
## Async Middleware
```ts
export default defineMiddleware(async (to, from, next) => {
try {
const user = await fetchUserInfo()
if (user.isBanned) {
next('/pages/banned/index')
} else {
next()
}
} catch (error) {
next('/pages/error/index')
}
})
```

name: vite-plugin-uni-pages
description: File-based routing system for Vite-powered uni-app projects with automatic page discovery and TypeScript support
---
# vite-plugin-uni-pages
Provides file-based routing for uni-app projects using Vite. Automatically generates `pages.json` configuration from your file structure.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-pages
```
## Basic Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import UniPages from '@uni-helper/vite-plugin-uni-pages'
import { defineConfig } from 'vite'
// Place UniPages before Uni
export default defineConfig({
plugins: [UniPages(), Uni()],
})
```
## TypeScript Support
Add types to `tsconfig.json`:
```json
{
"compilerOptions": {
"types": ["@uni-helper/vite-plugin-uni-pages"]
}
}
```
## Global Configuration
Create `pages.config.ts` (or .js/.json) for global settings:
```ts
// pages.config.ts
import { defineUniPages } from '@uni-helper/vite-plugin-uni-pages'
export default defineUniPages({
// Optional: manual pages have highest priority
pages: [],
globalStyle: {
navigationBarTextStyle: 'black',
navigationBarTitleText: '@uni-helper',
},
})
```
## Virtual Module
Access page metadata via virtual module:
```ts
/// <reference types="@uni-helper/vite-plugin-uni-pages/client" />
import { pages } from 'virtual:uni-pages'
console.log(pages)
```
## definePage Macro
Define page configuration directly in SFC files:
```vue
<script setup lang="ts">
// Object form
definePage({
style: {
navigationBarTitleText: 'hello world',
},
middlewares: ['auth'],
})
// Function form (supports TypeScript, async)
definePage(() => {
return {
style: {
navigationBarTitleText: 'dynamic title',
},
}
})
// Async form
definePage(async () => {
const title = await fetchTitle()
return {
style: { navigationBarTitleText: title },
}
})
</script>
```
### Important Notes for definePage
- Write inside `<script>` block
- `definePage` runs in a different scope than SFC (no access to SFC variables)
- Page path is auto-generated from file path
- Only one `definePage` per file
- Supports importing external libraries (pure JS only)
- Supports TypeScript type imports (types are stripped)
### Using with Condition Compile
```vue
<script setup>
import { isH5 } from '@uni-helper/uni-env'
definePage(() => {
const title = isH5 ? 'H5 Environment' : 'Other Platform'
return {
style: { navigationBarTitleText: title },
}
})
</script>
```
## Configuration Options
```ts
export interface Options {
/** Generate TypeScript declarations */
dts?: boolean | string // default: true (outputs uni-pages.d.ts)
/** Config file pattern */
configSource: string // default: 'pages.config.(ts|mts|cts|js|cjs|mjs|json)'
/** Default home page */
homePage: string // default: 'pages/index' or 'pages/index/index'
/** Merge with existing pages.json */
mergePages: boolean // default: true
/** Pages directory */
dir: string // default: 'src/pages'
/** Sub-packages directories */
subPackages: string[] // e.g., ['src/pages-sub']
/** Output directory for pages.json */
outDir: string // default: 'src'
/** Exclude patterns */
exclude: string[] // default: []
/** Route block language in SFC */
routeBlockLang: 'json5' | 'jsonc' | 'json' | 'yaml' | 'yml' // default: 'json5'
// Lifecycle hooks
onBeforeLoadUserConfig?: (ctx: PageContext) => void
onAfterLoadUserConfig?: (ctx: PageContext) => void
onBeforeScanPages?: (ctx: PageContext) => void
onAfterScanPages?: (ctx: PageContext) => void
onBeforeMergePageMetaData?: (ctx: PageContext) => void
onAfterMergePageMetaData?: (ctx: PageContext) => void
onBeforeWriteFile?: (ctx: PageContext) => void
onAfterWriteFile?: (ctx: PageContext) => void
}
```
## Usage with Layouts
```vue
<script setup>
definePage({
layout: 'default', // Specify layout
middlewares: ['auth'],
})
</script>
```

name: vite-plugin-uni-platform-modifier
description: Platform modifiers for attributes and directives in uni-app - optimize bundle size by removing unused platform code
---
# vite-plugin-uni-platform-modifier
Add platform modifiers to attributes and directives for conditional compilation at the template level. Reduces bundle size by removing code for other platforms.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-platform-modifier
```
## Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import UniPlatformModifier from '@uni-helper/vite-plugin-uni-platform-modifier'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [UniPlatformModifier(), Uni()],
})
```
## Platform Modifiers
### Directive Modifiers
```vue
<template>
<!-- Only render on H5 -->
<view v-if.h5="condition">H5 only content</view>
<!-- Only render on WeChat -->
<button v-if.mp-weixin="true">WeChat specific</button>
<!-- Only render on App -->
<native-view v-if.app="true">Native view</native-view>
<!-- Platform-specific event -->
<view @click.h5="handleH5Click" @click.mp-weixin="handleWeChatClick">
Platform-specific click
</view>
</template>
```
### Attribute Modifiers
```vue
<template>
<!-- Different classes per platform -->
<view class.h5="h5-container" class.mp-weixin="wechat-container">
Content
</view>
<!-- Platform-specific styles -->
<view :style.h5="{ padding: '20px' }" :style.app="{ padding: '10px' }">
Styled content
</view>
</template>
```
## Supported Platforms
| Modifier | Platform |
|----------|----------|
| `.h5` | H5/Web |
| `.mp-weixin` | WeChat Mini Program |
| `.mp-alipay` | Alipay Mini Program |
| `.mp-baidu` | Baidu Smart Program |
| `.mp-toutiao` | Douyin Mini Program |
| `.mp-qq` | QQ Mini Program |
| `.app` | iOS/Android App |
## How It Works
The plugin transforms templates at build time:
```vue
<!-- Source -->
<view v-if.h5="show">H5 Only</view>
<!-- Transformed for H5 build -->
<view v-if="show">H5 Only</view>
<!-- Removed for non-H5 builds -->
```
## Use Cases
- Platform-specific UI components
- Different interactions per platform
- Platform-optimized styles
- Conditional event handlers
## Combining with Other Plugins
```ts
// vite.config.ts
export default defineConfig({
plugins: [
UniComponents(),
UniPages(),
UniPlatform(), // File-based platform
UniPlatformModifier(), // Directive/attribute modifiers
Uni(),
],
})
```

name: vite-plugin-uni-platform
description: File-based platform compilation for uni-app - compile different files based on target platform
---
# vite-plugin-uni-platform
Compile different files based on target platform using file naming conventions. Supports platform-specific implementations without conditional compilation.
## Installation
```bash
npm i -D @uni-helper/vite-plugin-uni-platform
```
## Setup
```ts
// vite.config.ts
import Uni from '@dcloudio/vite-plugin-uni'
import UniPlatform from '@uni-helper/vite-plugin-uni-platform'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [UniPlatform(), Uni()],
})
```
## File Naming Convention
Use platform suffixes in filenames:
```
src/
utils/
request.ts # Default implementation
request.h5.ts # H5-specific
request.mp-weixin.ts # WeChat Mini Program
request.app.ts # App (iOS/Android)
```
## Supported Platforms
| Suffix | Platform |
|--------|----------|
| `.h5.ts` | H5/Web |
| `.mp-weixin.ts` | WeChat Mini Program |
| `.mp-alipay.ts` | Alipay Mini Program |
| `.mp-baidu.ts` | Baidu Smart Program |
| `.mp-toutiao.ts` | Douyin Mini Program |
| `.mp-qq.ts` | QQ Mini Program |
| `.mp-kuaishou.ts` | Kuaishou Mini Program |
| `.app.ts` | iOS/Android App |
| `.app-plus.ts` | App (alternative) |
| `.harmony` | HarmonyOS |
## Import Usage
Import without the platform suffix:
```ts
// This automatically resolves to the correct platform version
import { request } from './utils/request'
```
## Example
```ts
// utils/request.ts - Default implementation
export const request = (options: RequestOptions) => {
return uni.request(options)
}
// utils/request.h5.ts - H5 with axios
import axios from 'axios'
export const request = (options: RequestOptions) => {
return axios.request(options)
}
// utils/request.mp-weixin.ts - WeChat specific
export const request = (options: RequestOptions) => {
// Add WeChat-specific headers
return uni.request({
...options,
header: {
...options.header,
'X-Platform': 'weixin',
},
})
}
```
## Benefits
- Cleaner code without `#ifdef` conditions
- Type-safe platform implementations
- Tree-shaking removes unused platform code
- Better IDE support and navigation

## Pre-configured Plugins
The template includes these pre-configured plugins:
```ts
// vite.config.ts
export default defineConfig({
plugins: [
UniComponents({
resolvers: [AnoUIResolver()],
}),
UniPages(),
UniLayouts(),
UniManifest(),
Uni(),
],
})
```
## Auto Imports
### Components
Components in `src/components/` are auto-imported:
```vue
<template>
<!-- No import needed -->
<MyButton />
</template>
```
### Composables
Files in `src/composables/` are auto-imported:
```ts
// src/composables/useCounter.ts
export function useCounter() {
const count = ref(0)
const inc = () => count.value++
return { count, inc }
}
```
```vue
<script setup>
// No import needed
const { count, inc } = useCounter()
</script>
```
### Vue APIs
Vue APIs are auto-imported:
```vue
<script setup>
// No need to import ref, computed, etc.
const count = ref(0)
const doubled = computed(() => count.value * 2)
</script>
```
## Routing
File-based routing with pages in `src/pages/`:
```
pages/
├── index.vue # /pages/index/index
├── about.vue # /pages/about/index
└── user/
├── index.vue # /pages/user/index
└── [id].vue # /pages/user/:id
```
### Page Configuration
```vue
<script setup>
definePage({
style: {
navigationBarTitleText: 'About',
},
layout: 'default',
})
</script>
```
## Layouts
Create layouts in `src/layouts/`:
```vue
<!-- src/layouts/default.vue -->
<template>
<view class="layout">
<slot name="header" />
<slot />
<slot name="footer" />
</view>
</template>
```
Apply in pages:
```vue
<script setup>
definePage({
layout: 'default',
})
</script>
<template>
<template #header>
<NavBar />
</template>
<div>Content</div>
</template>
```
## Styling with UnoCSS
```vue
<template>
<view class="p-32 bg-gray-100">
<text class="text-32 font-bold text-primary">
Styled with UnoCSS
</text>
</view>
</template>
```
## State Management with Pinia
```ts
// src/stores/user.ts
import { defineStore } from 'pinia'
export const useUserStore = defineStore('user', () => {
const name = ref('')
const isLoggedIn = computed(() => !!name.value)
function login(userName: string) {
name.value = userName
}
return { name, isLoggedIn, login }
})
```
```vue
<script setup>
const user = useUserStore()
</script>
```
## Data Fetching
```vue
<script setup>
const { data: users, pending, error } = useFetch('/api/users')
</script>
<template>
<view v-if="pending">Loading...</view>
<view v-else-if="error">Error: {{ error.message }}</view>
<view v-else>
<view v-for="user in users" :key="user.id">
{{ user.name }}
</view>
</view>
</template>
```

# uni-env
Runtime environment detection utilities for uni-app. Detect the current platform in a type-safe way.
## Installation
```bash
npm i @uni-helper/uni-env
```
## Usage
```ts
import { isH5, isMpWeixin, isApp, isMp } from '@uni-helper/uni-env'
if (isH5) {
console.log('Running in H5')
}
if (isMpWeixin) {
console.log('Running in WeChat Mini Program')
}
```
## Available Detectors
### Platform Groups
| Detector | Description |
|----------|-------------|
| `isH5` | H5/Web platform |
| `isApp` | iOS/Android App |
| `isMp` | Any Mini Program |
| `isQuickapp` | Quick App |
### Mini Program Detectors
| Detector | Description |
|----------|-------------|
| `isMpWeixin` | WeChat Mini Program |
| `isMpAlipay` | Alipay Mini Program |
| `isMpBaidu` | Baidu Smart Program |
| `isMpToutiao` | Douyin Mini Program |
| `isMpQQ` | QQ Mini Program |
| `isMpKuaishou` | Kuaishou Mini Program |
| `isMpJd` | JD Mini Program |
| `isMpHarmony` | HarmonyOS Meta Service |
| `isMpLark` | Feishu/Lark Mini Program |
### Development Detectors
| Detector | Description |
|----------|-------------|
| `isDev` | Development environment |
| `isProd` | Production environment |
## Use Cases
### Conditional Logic
```ts
import { isH5, isMpWeixin, isApp } from '@uni-helper/uni-env'
function getStorageAdapter() {
if (isH5) {
return new LocalStorageAdapter()
}
if (isMpWeixin) {
return new WechatStorageAdapter()
}
if (isApp) {
return new NativeStorageAdapter()
}
return new UniStorageAdapter()
}
```
### Platform-Specific Features
```ts
import { isH5, isMpWeixin } from '@uni-helper/uni-env'
function share(content: ShareContent) {
if (isMpWeixin) {
// Use WeChat share API
wx.showShareMenu({ withShareTicket: true })
} else if (isH5) {
// Use Web Share API
navigator.share({
title: content.title,
url: content.url,
})
} else {
// Use uni-app generic share
uni.share({
title: content.title,
path: content.path,
})
}
}
```
### With definePage
```ts
import { isH5 } from '@uni-helper/uni-env'
definePage(() => {
const title = isH5 ? 'H5 Version' : 'Mobile Version'
return {
style: {
navigationBarTitleText: title,
},
}
})
```
## Important Note
This package is primarily for **plugin developers**. For runtime conditional compilation, use uni-app's [official conditional compilation](https://uniapp.dcloud.net.cn/tutorial/platform.html#preprocessor) with `/* #ifdef */` comments.
For better conditional compilation support, consider using [unplugin-preprocessor-directives](https://github.com/KeJunMao/unplugin-preprocessor-directives).
## Comparison with Conditional Compilation
```ts
// Runtime detection (uni-env)
import { isH5 } from '@uni-helper/uni-env'
if (isH5) {
// This code exists in all builds
doH5Thing()
}
// Build-time conditional compilation
// #ifdef H5
doH5Thing()
// #endif
// This code only exists in H5 builds
```
Choose based on your needs:
- Use **uni-env** for runtime detection when you need the same bundle for multiple platforms
- Use **conditional compilation** for build-time optimization and smaller bundles

UnoCSS is an instant atomic CSS engine designed to be flexible and extensible. The core is un-opinionated - all CSS utilities are provided via presets. It's a superset of Tailwind CSS, so you can reuse your Tailwind knowledge for basic syntax usage.
**Important:** Before writing UnoCSS code, agents should check for `uno.config.*` or `unocss.config.*` files in the project root to understand what presets, rules, and shortcuts are available. If the project setup is unclear, avoid using attributify mode and other advanced features - stick to basic `class` usage.
> The skill is based on UnoCSS 66.x, generated at 2026-01-28.

name: unocss-configuration
description: Config file setup and all configuration options for UnoCSS
---
# UnoCSS Configuration
UnoCSS is configured via a dedicated config file in your project root.
## Config File
**Recommended:** Use a dedicated `uno.config.ts` file for best IDE support and HMR.
```ts
// uno.config.ts
import {
defineConfig,
presetAttributify,
presetIcons,
presetTypography,
presetWebFonts,
presetWind3,
transformerDirectives,
transformerVariantGroup
} from 'unocss'
export default defineConfig({
shortcuts: [
// ...
],
theme: {
colors: {
// ...
}
},
presets: [
presetWind3(),
presetAttributify(),
presetIcons(),
presetTypography(),
presetWebFonts({
fonts: {
// ...
},
}),
],
transformers: [
transformerDirectives(),
transformerVariantGroup(),
],
})
```
UnoCSS automatically looks for `uno.config.{js,ts,mjs,mts}` or `unocss.config.{js,ts,mjs,mts}` in the project root.
## Key Configuration Options
### rules
Define CSS utility rules. Later entries have higher priority.
```ts
rules: [
['m-1', { margin: '0.25rem' }],
[/^m-(\d+)$/, ([, d]) => ({ margin: `${d / 4}rem` })],
]
```
### shortcuts
Combine multiple rules into a single shorthand.
```ts
shortcuts: {
'btn': 'py-2 px-4 font-semibold rounded-lg shadow-md',
}
```
### theme
Theme object for design tokens shared between rules.
```ts
theme: {
colors: {
brand: '#942192',
},
breakpoints: {
sm: '640px',
md: '768px',
},
}
```
### presets
Predefined configurations bundling rules, variants, and themes.
```ts
presets: [
presetWind3(),
presetIcons(),
]
```
### transformers
Transform source code to support special syntax.
```ts
transformers: [
transformerDirectives(),
transformerVariantGroup(),
]
```
### variants
Preprocess selectors with ability to rewrite CSS output.
### extractors
Handle source files and extract utility class names.
### preflights
Inject raw CSS globally.
### layers
Control the order of CSS layers. Default is `0`.
```ts
layers: {
'components': -1,
'default': 1,
'utilities': 2,
}
```
### safelist
Utilities that are always included in output.
```ts
safelist: ['p-1', 'p-2', 'p-3']
```
### blocklist
Utilities that are always excluded.
```ts
blocklist: ['p-1', /^p-[2-4]$/]
```
### content
Configure where to extract utilities from.
```ts
content: {
pipeline: {
include: [/\.(vue|svelte|tsx|html)($|\?)/],
},
filesystem: ['src/**/*.php'],
}
```
### separators
Variant separator characters. Default: `[':', '-']`
### outputToCssLayers
Output UnoCSS layers as CSS Cascade Layers.
```ts
outputToCssLayers: true
```
## Specifying Config File Location
```ts
// vite.config.ts
import UnoCSS from 'unocss/vite'
export default defineConfig({
plugins: [
UnoCSS({
configFile: '../my-uno.config.ts',
}),
],
})
```

name: unocss-extracting
description: How UnoCSS extracts utilities from source code
---
# Extracting
UnoCSS searches for utility usages in your codebase and generates CSS on-demand.
## Content Sources
### Pipeline Extraction (Vite/Webpack)
Most efficient - extracts from build tool pipeline.
**Default file types:** `.jsx`, `.tsx`, `.vue`, `.md`, `.html`, `.svelte`, `.astro`, `.marko`
**Not included by default:** `.js`, `.ts`
```ts
export default defineConfig({
content: {
pipeline: {
include: [
/\.(vue|svelte|[jt]sx|mdx?|astro|html)($|\?)/,
'src/**/*.{js,ts}', // Add js/ts
],
},
},
})
```
### Filesystem Extraction
For files not in build pipeline:
```ts
export default defineConfig({
content: {
filesystem: [
'src/**/*.php',
'public/*.html',
],
},
})
```
### Inline Text Extraction
```ts
export default defineConfig({
content: {
inline: [
'<div class="p-4 text-red">Some text</div>',
async () => (await fetch('https://example.com')).text(),
],
},
})
```
## Magic Comments
### @unocss-include
Force scan a file:
```ts
// @unocss-include
export const classes = {
active: 'bg-primary text-white',
}
```
### @unocss-ignore
Skip entire file:
```ts
// @unocss-ignore
```
### @unocss-skip-start / @unocss-skip-end
Skip specific blocks:
```html
<p class="text-green">Extracted</p>
<!-- @unocss-skip-start -->
<p class="text-red">NOT extracted</p>
<!-- @unocss-skip-end -->
```
## Limitations
UnoCSS works at **build time** - dynamic classes don't work:
```html
<!-- Won't work! -->
<div class="p-${size}"></div>
```
### Solutions
**1. Safelist** - Pre-generate known values:
```ts
safelist: ['p-1', 'p-2', 'p-3', 'p-4']
```
**2. Static mapping** - List combinations statically:
```ts
const colors = {
red: 'text-red border-red',
blue: 'text-blue border-blue',
}
```
**3. Runtime** - Use `@unocss/runtime` for true runtime generation.
## Custom Extractors
```ts
extractors: [
{
name: 'my-extractor',
extract({ code }) {
return code.match(/class:[\w-]+/g) || []
},
},
]
```

# Layers and Preflights
Control CSS output order and inject global CSS.
## Layers
Set layer on rules:
```ts
rules: [
[/^m-(\d)$/, ([, d]) => ({ margin: `${d / 4}rem` }), { layer: 'utilities' }],
['btn', { padding: '4px' }], // default layer
]
```
### Layer Ordering
```ts
layers: {
'components': -1,
'default': 1,
'utilities': 2,
}
```
### Import Layers Separately
```ts
import 'uno:components.css'
import 'uno.css'
import './my-custom.css'
import 'uno:utilities.css'
```
### CSS Cascade Layers
```ts
outputToCssLayers: true
// Or with custom names
outputToCssLayers: {
cssLayerName: (layer) => {
if (layer === 'default') return 'utilities'
if (layer === 'shortcuts') return 'utilities.shortcuts'
}
}
```
## Layer Variants
```html
<!-- UnoCSS layer -->
<p class="uno-layer-my-layer:text-xl">
<!-- CSS @layer -->
<p class="layer-my-layer:text-xl">
```
## Preflights
Inject raw CSS globally:
```ts
preflights: [
{
getCSS: ({ theme }) => `
* {
color: ${theme.colors.gray?.[700] ?? '#333'};
margin: 0;
}
`,
},
]
```
With layer:
```ts
preflights: [
{
layer: 'base',
getCSS: () => `html { font-family: system-ui; }`,
},
]
```
## preset-wind4 Layers
| Layer | Description | Order |
|-------|-------------|-------|
| `properties` | CSS @property rules | -200 |
| `theme` | Theme CSS variables | -150 |
| `base` | Reset styles | -100 |

name: unocss-rules
description: Static and dynamic rules for generating CSS utilities in UnoCSS
---
# UnoCSS Rules
Rules define utility classes and the CSS they generate. UnoCSS has many built-in rules via presets and allows custom rules.
## Static Rules
Simple mapping from class name to CSS properties:
```ts
rules: [
['m-1', { margin: '0.25rem' }],
['font-bold', { 'font-weight': 700 }],
]
```
Usage: `<div class="m-1">` generates `.m-1 { margin: 0.25rem; }`
**Note:** Use CSS property syntax with hyphens (e.g., `font-weight` not `fontWeight`). Quote properties with hyphens.
## Dynamic Rules
Use RegExp matcher with function body for flexible utilities:
```ts
rules: [
// Match m-1, m-2, m-100, etc.
[/^m-(\d+)$/, ([, d]) => ({ margin: `${d / 4}rem` })],
// Access theme and context
[/^p-(\d+)$/, (match, ctx) => ({ padding: `${match[1] / 4}rem` })],
]
```
The function receives:
1. RegExp match result (destructure to get captured groups)
2. Context object with `theme`, `symbols`, etc.
## CSS Fallback Values
Return 2D array for CSS property fallbacks (browser compatibility):
```ts
rules: [
[/^h-(\d+)dvh$/, ([_, d]) => [
['height', `${d}vh`],
['height', `${d}dvh`],
]],
]
```
Generates: `.h-100dvh { height: 100vh; height: 100dvh; }`
## Special Symbols
Control CSS output with symbols from `@unocss/core`:
```ts
import { symbols } from '@unocss/core'
rules: [
['grid', {
[symbols.parent]: '@supports (display: grid)',
display: 'grid',
}],
]
```
### Available Symbols
| Symbol | Description |
|--------|-------------|
| `symbols.parent` | Parent wrapper (e.g., `@supports`, `@media`) |
| `symbols.selector` | Function to modify the selector |
| `symbols.layer` | Set the UnoCSS layer |
| `symbols.variants` | Array of variant handlers |
| `symbols.shortcutsNoMerge` | Disable merging in shortcuts |
| `symbols.noMerge` | Disable rule merging |
| `symbols.sort` | Override sorting order |
| `symbols.body` | Full control of CSS body |
## Multi-Selector Rules
Use generator functions to yield multiple CSS rules:
```ts
rules: [
[/^button-(.*)$/, function* ([, color], { symbols }) {
yield { background: color }
yield {
[symbols.selector]: selector => `${selector}:hover`,
background: `color-mix(in srgb, ${color} 90%, black)`
}
}],
]
```
Generates both `.button-red { background: red; }` and `.button-red:hover { ... }`
## Fully Controlled Rules
Return a string for complete CSS control (advanced):
```ts
import { defineConfig, toEscapedSelector as e } from 'unocss'
rules: [
[/^custom-(.+)$/, ([, name], { rawSelector, theme }) => {
const selector = e(rawSelector)
return `
${selector} { font-size: ${theme.fontSize.sm}; }
${selector}::after { content: 'after'; }
@media (min-width: ${theme.breakpoints.sm}) {
${selector} { font-size: ${theme.fontSize.lg}; }
}
`
}],
]
```
**Warning:** Fully controlled rules don't work with variants like `hover:`.
## Symbols.body for Variant Support
Use `symbols.body` to keep variant support with custom CSS:
```ts
rules: [
['custom-red', {
[symbols.body]: `
font-size: 1rem;
&::after { content: 'after'; }
& > .bar { color: red; }
`,
[symbols.selector]: selector => `:is(${selector})`,
}]
]
```
## Rule Ordering
Later rules have higher priority. Dynamic rules output is sorted alphabetically within the group.
## Rule Merging
UnoCSS merges rules with identical CSS bodies:
```html
<div class="m-2 hover:m2">
```
Generates:
```css
.hover\:m2:hover, .m-2 { margin: 0.5rem; }
```
Use `symbols.noMerge` to disable.

description: Force include or exclude specific utilities
---
# Safelist and Blocklist
Control which utilities are always included or excluded.
## Safelist
Utilities always included, regardless of detection:
```ts
export default defineConfig({
safelist: [
'p-1', 'p-2', 'p-3',
// Dynamic generation
...Array.from({ length: 4 }, (_, i) => `p-${i + 1}`),
],
})
```
### Function Form
```ts
safelist: [
'p-1',
() => ['m-1', 'm-2'],
(context) => {
const colors = Object.keys(context.theme.colors || {})
return colors.map(c => `bg-${c}-500`)
},
]
```
### Common Use Cases
```ts
safelist: [
// Dynamic colors from CMS
() => ['primary', 'secondary'].flatMap(c => [
`bg-${c}`, `text-${c}`, `border-${c}`,
]),
// Component variants
() => {
const variants = ['primary', 'danger']
const sizes = ['sm', 'md', 'lg']
return variants.flatMap(v => sizes.map(s => `btn-${v}-${s}`))
},
]
```
## Blocklist
Utilities never generated:
```ts
blocklist: [
'p-1', // Exact match
/^p-[2-4]$/, // Regex
]
```
### With Messages
```ts
blocklist: [
['bg-red-500', { message: 'Use bg-red-600 instead' }],
[/^text-xs$/, { message: 'Use text-sm for accessibility' }],
]
```
## Safelist vs Blocklist
| Feature | Safelist | Blocklist |
|---------|----------|-----------|
| Purpose | Always include | Always exclude |
| Strings | ✅ | ✅ |
| Regex | ❌ | ✅ |
| Functions | ✅ | ❌ |
**Note:** Blocklist wins if utility is in both.
## Best Practice
Prefer static mappings over safelist:
```ts
// Better: UnoCSS extracts automatically
const sizes = {
sm: 'text-sm p-2',
md: 'text-base p-4',
}
// Avoid: Large safelist
safelist: ['text-sm', 'text-base', 'p-2', 'p-4']
```

description: Combine multiple utility rules into single shorthand classes
---
# UnoCSS Shortcuts
Shortcuts combine multiple rules into a single shorthand, inspired by Windi CSS.
## Static Shortcuts
Define as an object mapping shortcut names to utility combinations:
```ts
shortcuts: {
// Multiple utilities combined
'btn': 'py-2 px-4 font-semibold rounded-lg shadow-md',
'btn-green': 'text-white bg-green-500 hover:bg-green-700',
// Single utility alias
'red': 'text-red-100',
}
```
Usage:
```html
<button class="btn btn-green">Click me</button>
```
## Dynamic Shortcuts
Use RegExp matcher with function, similar to dynamic rules:
```ts
shortcuts: [
// Static shortcuts can be in array too
{
btn: 'py-2 px-4 font-semibold rounded-lg shadow-md',
},
// Dynamic shortcut
[/^btn-(.*)$/, ([, c]) => `bg-${c}-400 text-${c}-100 py-2 px-4 rounded-lg`],
]
```
Now `btn-green` and `btn-red` generate:
```css
.btn-green {
padding: 0.5rem 1rem;
--un-bg-opacity: 1;
background-color: rgb(74 222 128 / var(--un-bg-opacity));
border-radius: 0.5rem;
--un-text-opacity: 1;
color: rgb(220 252 231 / var(--un-text-opacity));
}
```
## Accessing Theme in Shortcuts
Dynamic shortcuts receive context with theme access:
```ts
shortcuts: [
[/^badge-(.*)$/, ([, c], { theme }) => {
if (Object.keys(theme.colors).includes(c))
return `bg-${c}4:10 text-${c}5 rounded`
}],
]
```
## Shortcuts Layer
Shortcuts are output to the `shortcuts` layer by default. Configure with:
```ts
shortcutsLayer: 'my-shortcuts-layer'
```
## Key Points
- Later shortcuts have higher priority
- Shortcuts can reference other shortcuts
- Dynamic shortcuts work like dynamic rules
- Shortcuts are expanded at build time, not runtime
- All variants work with shortcuts (`hover:btn`, `dark:btn`, etc.)

name: unocss-theme
description: Theming system for colors, breakpoints, and design tokens
---
# UnoCSS Theme
UnoCSS supports theming similar to Tailwind CSS / Windi CSS. The `theme` property is deep-merged with the default theme.
## Basic Usage
```ts
theme: {
colors: {
veryCool: '#0000ff', // class="text-very-cool"
brand: {
primary: 'hsl(var(--hue, 217) 78% 51%)', // class="bg-brand-primary"
DEFAULT: '#942192' // class="bg-brand"
},
},
}
```
## Using Theme in Rules
Access theme values in dynamic rules:
```ts
rules: [
[/^text-(.*)$/, ([, c], { theme }) => {
if (theme.colors[c])
return { color: theme.colors[c] }
}],
]
```
## Using Theme in Variants
```ts
variants: [
{
name: 'variant-name',
match(matcher, { theme }) {
// Access theme.breakpoints, theme.colors, etc.
},
},
]
```
## Using Theme in Shortcuts
```ts
shortcuts: [
[/^badge-(.*)$/, ([, c], { theme }) => {
if (Object.keys(theme.colors).includes(c))
return `bg-${c}4:10 text-${c}5 rounded`
}],
]
```
## Breakpoints
**Warning:** Custom `breakpoints` object **overrides** the default, not merges.
```ts
theme: {
breakpoints: {
sm: '320px',
md: '640px',
},
}
```
Only `sm:` and `md:` variants will be available.
### Inherit Default Breakpoints
Use `extendTheme` to merge with defaults:
```ts
extendTheme: (theme) => {
return {
...theme,
breakpoints: {
...theme.breakpoints,
sm: '320px',
md: '640px',
},
}
}
```
**Note:** `verticalBreakpoints` works the same for vertical layout.
### Breakpoint Sorting
Breakpoints are sorted by size. Use consistent units to avoid errors:
```ts
theme: {
breakpoints: {
sm: '320px',
// Don't mix units - convert rem to px
// md: '40rem', // Bad
md: `${40 * 16}px`, // Good
lg: '960px',
},
}
```
## ExtendTheme
`extendTheme` lets you modify the merged theme object:
### Mutate Theme
```ts
extendTheme: (theme) => {
theme.colors.veryCool = '#0000ff'
theme.colors.brand = {
primary: 'hsl(var(--hue, 217) 78% 51%)',
}
}
```
### Replace Theme
Return a new object to completely replace:
```ts
extendTheme: (theme) => {
return {
...theme,
colors: {
...theme.colors,
veryCool: '#0000ff',
},
}
}
```
## Theme Differences in Presets
### preset-wind3 vs preset-wind4
| preset-wind3 | preset-wind4 |
|--------------|--------------|
| `fontFamily` | `font` |
| `fontSize` | `text.fontSize` |
| `lineHeight` | `text.lineHeight` or `leading` |
| `letterSpacing` | `text.letterSpacing` or `tracking` |
| `borderRadius` | `radius` |
| `easing` | `ease` |
| `breakpoints` | `breakpoint` |
| `boxShadow` | `shadow` |
| `transitionProperty` | `property` |
## Common Theme Keys
- `colors` - Color palette
- `breakpoints` - Responsive breakpoints
- `fontFamily` - Font stacks
- `fontSize` - Text sizes
- `spacing` - Spacing scale
- `borderRadius` - Border radius values
- `boxShadow` - Shadow definitions
- `animation` - Animation keyframes and timing

name: unocss-variants
description: Apply variations like hover:, dark:, responsive to rules
---
# UnoCSS Variants
Variants apply modifications to utility rules, like `hover:`, `dark:`, or responsive prefixes.
## How Variants Work
When matching `hover:m-2`:
1. `hover:m-2` is extracted from source
2. Sent to all variants for matching
3. `hover:` variant matches and returns `m-2`
4. Result `m-2` continues to next variants
5. Finally matches the rule `.m-2 { margin: 0.5rem; }`
6. Variant transformation applied: `.hover\:m-2:hover { margin: 0.5rem; }`
## Creating Custom Variants
```ts
variants: [
// hover: variant
(matcher) => {
if (!matcher.startsWith('hover:'))
return matcher
return {
// Remove prefix, pass to next variants/rules
matcher: matcher.slice(6),
// Modify the selector
selector: s => `${s}:hover`,
}
},
],
rules: [
[/^m-(\d)$/, ([, d]) => ({ margin: `${d / 4}rem` })],
]
```
## Variant Return Object
- `matcher` - The processed class name to pass forward
- `selector` - Function to customize the CSS selector
- `parent` - Wrapper like `@media`, `@supports`
- `layer` - Specify output layer
- `sort` - Control ordering
## Built-in Variants (preset-wind3)
### Pseudo-classes
- `hover:`, `focus:`, `active:`, `visited:`
- `first:`, `last:`, `odd:`, `even:`
- `disabled:`, `checked:`, `required:`
- `focus-within:`, `focus-visible:`
### Pseudo-elements
- `before:`, `after:`
- `placeholder:`, `selection:`
- `marker:`, `file:`
### Responsive
- `sm:`, `md:`, `lg:`, `xl:`, `2xl:`
- `lt-sm:` (less than sm)
- `at-lg:` (at lg only)
### Dark Mode
- `dark:` - Class-based dark mode (default)
- `@dark:` - Media query dark mode
### Group/Peer
- `group-hover:`, `group-focus:`
- `peer-checked:`, `peer-focus:`
### Container Queries
- `@container`, `@sm:`, `@md:`
### Print
- `print:`
### Supports
- `supports-[display:grid]:`
### Aria
- `aria-checked:`, `aria-disabled:`
### Data Attributes
- `data-[state=open]:`
## Dark Mode Configuration
### Class-based (default)
```ts
presetWind3({
dark: 'class'
})
```
```html
<div class="dark:bg-gray-800">
```
Generates: `.dark .dark\:bg-gray-800 { ... }`
### Media Query
```ts
presetWind3({
dark: 'media'
})
```
Generates: `@media (prefers-color-scheme: dark) { ... }`
### Opt-in Media Query
Use `@dark:` regardless of config:
```html
<div class="@dark:bg-gray-800">
```
### Custom Selectors
```ts
presetWind3({
dark: {
light: '.light-mode',
dark: '.dark-mode',
}
})
```
## CSS @layer Variant
Native CSS `@layer` support:
```html
<div class="layer-foo:p-4" />
```
Generates:
```css
@layer foo {
.layer-foo\:p-4 { padding: 1rem; }
}
```
## Breakpoint Differences from Windi CSS
| Windi CSS | UnoCSS |
|-----------|--------|
| `<sm:p-1` | `lt-sm:p-1` |
| `@lg:p-1` | `at-lg:p-1` |
| `>xl:p-1` | `xl:p-1` |
## Media Hover (Experimental)
Addresses sticky hover on touch devices:
```html
<div class="@hover-text-red">
```
Generates:
```css
@media (hover: hover) and (pointer: fine) {
.\@hover-text-red:hover { color: rgb(248 113 113); }
}
```

# UnoCSS Nuxt Integration
The official Nuxt module for UnoCSS.
## Installation
```bash
pnpm add -D unocss @unocss/nuxt
```
Add to Nuxt config:
```ts
// nuxt.config.ts
export default defineNuxtConfig({
modules: [
'@unocss/nuxt',
],
})
```
Create config file:
```ts
// uno.config.ts
import { defineConfig, presetWind3 } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
],
})
```
**Note:** The `uno.css` entry is automatically injected by the module.
## Support Status
| Build Tool | Nuxt 2 | Nuxt Bridge | Nuxt 3 |
|------------|--------|-------------|--------|
| Webpack Dev | ✅ | ✅ | 🚧 |
| Webpack Build | ✅ | ✅ | ✅ |
| Vite Dev | - | ✅ | ✅ |
| Vite Build | - | ✅ | ✅ |
## Configuration
### Using uno.config.ts (Recommended)
Use a dedicated config file for best IDE support:
```ts
// uno.config.ts
import { defineConfig, presetWind3, presetIcons } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
presetIcons(),
],
shortcuts: {
'btn': 'py-2 px-4 font-semibold rounded-lg',
},
})
```
### Nuxt Layers Support
Enable automatic config merging from Nuxt layers:
```ts
// nuxt.config.ts
export default defineNuxtConfig({
unocss: {
nuxtLayers: true,
},
})
```
Then in your root config:
```ts
// uno.config.ts
import config from './.nuxt/uno.config.mjs'
export default config
```
Or extend the merged config:
```ts
// uno.config.ts
import { mergeConfigs } from '@unocss/core'
import config from './.nuxt/uno.config.mjs'
export default mergeConfigs([config, {
// Your overrides
shortcuts: {
'custom': 'text-red-500',
},
}])
```
## Common Setup Example
```ts
// nuxt.config.ts
export default defineNuxtConfig({
modules: [
'@unocss/nuxt',
],
})
```
```ts
// uno.config.ts
import {
defineConfig,
presetAttributify,
presetIcons,
presetTypography,
presetWebFonts,
presetWind3,
transformerDirectives,
transformerVariantGroup,
} from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
presetAttributify(),
presetIcons({
scale: 1.2,
}),
presetTypography(),
presetWebFonts({
fonts: {
sans: 'DM Sans',
mono: 'DM Mono',
},
}),
],
transformers: [
transformerDirectives(),
transformerVariantGroup(),
],
shortcuts: [
['btn', 'px-4 py-1 rounded inline-block bg-teal-600 text-white cursor-pointer hover:bg-teal-700 disabled:cursor-default disabled:bg-gray-600 disabled:opacity-50'],
],
})
```
## Usage in Components
```vue
<template>
<div class="p-4 text-center">
<h1 class="text-3xl font-bold text-blue-600">
Hello UnoCSS!
</h1>
<button class="btn mt-4">
Click me
</button>
</div>
</template>
```
With attributify mode:
```vue
<template>
<div p="4" text="center">
<h1 text="3xl blue-600" font="bold">
Hello UnoCSS!
</h1>
</div>
</template>
```
## Inspector
In development, visit `/_nuxt/__unocss` to access the UnoCSS inspector.
## Key Differences from Vite
- No need to import `virtual:uno.css` - automatically injected
- Config file discovery works the same
- All Vite plugin features available
- Nuxt layers config merging available

name: unocss-vite-integration
description: Setting up UnoCSS with Vite and framework-specific tips
---
# UnoCSS Vite Integration
The Vite plugin is the most common way to use UnoCSS.
## Installation
```bash
pnpm add -D unocss
```
```ts
// vite.config.ts
import UnoCSS from 'unocss/vite'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [
UnoCSS(),
],
})
```
Create config file:
```ts
// uno.config.ts
import { defineConfig, presetWind3 } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
],
})
```
Add to entry:
```ts
// main.ts
import 'virtual:uno.css'
```
## Modes
### global (default)
Standard mode - generates global CSS injected via `uno.css` import.
```ts
import 'virtual:uno.css'
```
### vue-scoped
Injects generated CSS into Vue SFC `<style scoped>`.
```ts
UnoCSS({
mode: 'vue-scoped',
})
```
### shadow-dom
For Web Components using Shadow DOM:
```ts
UnoCSS({
mode: 'shadow-dom',
})
```
Add placeholder in component styles:
```ts
const template = document.createElement('template')
template.innerHTML = `
<style>
:host { ... }
@unocss-placeholder
</style>
<div class="m-1em">...</div>
`
```
### per-module (experimental)
Generates CSS per module with optional scoping.
### dist-chunk (experimental)
Generates CSS per chunk on build for MPA.
## DevTools Support
Edit classes directly in browser DevTools:
```ts
import 'virtual:uno.css'
import 'virtual:unocss-devtools'
```
**Warning:** Uses MutationObserver to detect changes. Dynamic classes from scripts will also be included.
## Framework-Specific Setup
### React
```ts
// vite.config.ts
import React from '@vitejs/plugin-react'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
UnoCSS(), // Must be before React when using attributify
React(),
],
}
```
**Note:** Remove `tsc` from build script if using `@unocss/preset-attributify`.
### Vue
Works out of the box with `@vitejs/plugin-vue`.
### Svelte
```ts
import { svelte } from '@sveltejs/vite-plugin-svelte'
import extractorSvelte from '@unocss/extractor-svelte'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
UnoCSS({
extractors: [extractorSvelte()],
}),
svelte(),
],
}
```
Supports `class:foo` and `class:foo={bar}` syntax.
### SvelteKit
Same as Svelte, use `sveltekit()` from `@sveltejs/kit/vite`.
### Solid
```ts
import UnoCSS from 'unocss/vite'
import solidPlugin from 'vite-plugin-solid'
export default {
plugins: [
UnoCSS(),
solidPlugin(),
],
}
```
### Preact
```ts
import Preact from '@preact/preset-vite'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
UnoCSS(),
Preact(),
],
}
```
### Elm
```ts
import Elm from 'vite-plugin-elm'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
Elm(),
UnoCSS(),
],
}
```
### Web Components (Lit)
```ts
UnoCSS({
mode: 'shadow-dom',
shortcuts: [
{ 'cool-blue': 'bg-blue-500 text-white' },
],
})
```
```ts
// my-element.ts
@customElement('my-element')
export class MyElement extends LitElement {
static styles = css`
:host { ... }
@unocss-placeholder
`
}
```
Supports `part-[<part-name>]:<utility>` for `::part` styling.
## Inspector
Visit `http://localhost:5173/__unocss` in dev mode to:
- Inspect generated CSS rules
- See applied classes per file
- Test utilities in REPL
## Legacy Browser Support
With `@vitejs/plugin-legacy`:
```ts
import legacy from '@vitejs/plugin-legacy'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
UnoCSS({
legacy: {
renderModernChunks: false,
},
}),
legacy({
targets: ['defaults', 'not IE 11'],
renderModernChunks: false,
}),
],
}
```
## VanillaJS / TypeScript
By default, `.js` and `.ts` files are not extracted. Configure to include:
```ts
// uno.config.ts
export default defineConfig({
content: {
pipeline: {
include: [
/\.(vue|svelte|[jt]sx|html)($|\?)/,
'src/**/*.{js,ts}',
],
},
},
})
```
Or use magic comment in files:
```ts
// @unocss-include
export const classes = {
active: 'bg-primary text-white',
}
```

name: preset-attributify
description: Group utilities in HTML attributes instead of class
---
# Preset Attributify
Group utilities in HTML attributes for better readability.
## Installation
```ts
import { defineConfig, presetAttributify, presetWind3 } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
presetAttributify(),
],
})
```
## Basic Usage
Instead of long class strings:
```html
<button class="bg-blue-400 hover:bg-blue-500 text-sm text-white font-mono font-light py-2 px-4 rounded border-2 border-blue-200">
Button
</button>
```
Group by prefix in attributes:
```html
<button
bg="blue-400 hover:blue-500"
text="sm white"
font="mono light"
p="y-2 x-4"
border="2 rounded blue-200"
>
Button
</button>
```
## Prefix Self-Referencing
For utilities matching their prefix (`flex`, `grid`, `border`), use `~`:
```html
<!-- Before -->
<button class="border border-red">Button</button>
<!-- After -->
<button border="~ red">Button</button>
```
## Valueless Attributify
Use utilities as boolean attributes:
```html
<div m-2 rounded text-teal-400 />
```
## Handling Property Conflicts
When attribute names conflict with HTML properties:
```html
<!-- Use un- prefix -->
<a un-text="red">Text color to red</a>
```
### Enforce Prefix
```ts
presetAttributify({
prefix: 'un-',
prefixedOnly: true,
})
```
## Options
```ts
presetAttributify({
strict: false, // Only generate CSS for attributify
prefix: 'un-', // Attribute prefix
prefixedOnly: false, // Require prefix for all
nonValuedAttribute: true, // Support valueless attributes
ignoreAttributes: [], // Attributes to ignore
trueToNonValued: false, // Treat value="true" as valueless
})
```
## TypeScript Support
### Vue 3
```ts
// html.d.ts
declare module '@vue/runtime-dom' {
interface HTMLAttributes { [key: string]: any }
}
declare module '@vue/runtime-core' {
interface AllowedComponentProps { [key: string]: any }
}
export {}
```
### React
```ts
import type { AttributifyAttributes } from '@unocss/preset-attributify'
declare module 'react' {
interface HTMLAttributes<T> extends AttributifyAttributes {}
}
```
## JSX Support
For JSX where `<div foo>` becomes `<div foo={true}>`:
```ts
import { transformerAttributifyJsx } from 'unocss'
export default defineConfig({
transformers: [
transformerAttributifyJsx(),
],
})
```
**Important:** Only use attributify if `uno.config.*` shows `presetAttributify()` is enabled.

name: preset-icons
description: Pure CSS icons using Iconify with any icon set
---
# Preset Icons
Use any icon as a pure CSS class, powered by Iconify.
## Installation
```bash
pnpm add -D @unocss/preset-icons @iconify-json/[collection-name]
```
Example: `@iconify-json/mdi` for Material Design Icons, `@iconify-json/carbon` for Carbon icons.
```ts
import { defineConfig, presetIcons } from 'unocss'
export default defineConfig({
presets: [
presetIcons(),
],
})
```
## Usage
Two naming conventions:
- `<prefix><collection>-<icon>` → `i-ph-anchor-simple-thin`
- `<prefix><collection>:<icon>` → `i-ph:anchor-simple-thin`
```html
<!-- Phosphor anchor icon -->
<div class="i-ph-anchor-simple-thin" />
<!-- Material Design alarm with color -->
<div class="i-mdi-alarm text-orange-400" />
<!-- Large Vue logo -->
<div class="i-logos-vue text-3xl" />
<!-- Dynamic: Sun in light mode, Moon in dark -->
<button class="i-carbon-sun dark:i-carbon-moon" />
<!-- Hover effect -->
<div class="i-twemoji-grinning-face-with-smiling-eyes hover:i-twemoji-face-with-tears-of-joy" />
```
Browse icons at [icones.js.org](https://icones.js.org/) or [Iconify](https://icon-sets.iconify.design/).
## Icon Modes
Icons automatically choose between `mask` (monochrome) and `background-img` (colorful).
### Force Specific Mode
- `?mask` - Render as mask (colorable with `currentColor`)
- `?bg` - Render as background image (preserves original colors)
```html
<!-- Original with colors -->
<div class="i-vscode-icons:file-type-light-pnpm" />
<!-- Force mask mode, apply custom color -->
<div class="i-vscode-icons:file-type-light-pnpm?mask text-red-300" />
```
## Options
```ts
presetIcons({
scale: 1.2, // Scale relative to font size
prefix: 'i-', // Class prefix (default)
mode: 'auto', // 'auto' | 'mask' | 'bg'
extraProperties: {
'display': 'inline-block',
'vertical-align': 'middle',
},
warn: true, // Warn on missing icons
autoInstall: true, // Auto-install missing icon sets
cdn: 'https://esm.sh/', // CDN for browser usage
})
```
## Custom Icon Collections
### Inline SVGs
```ts
presetIcons({
collections: {
custom: {
circle: '<svg viewBox="0 0 120 120"><circle cx="60" cy="60" r="50"></circle></svg>',
},
}
})
```
Usage: `<span class="i-custom:circle"></span>`
### File System Loader
```ts
import { FileSystemIconLoader } from '@iconify/utils/lib/loader/node-loaders'
presetIcons({
collections: {
'my-icons': FileSystemIconLoader(
'./assets/icons',
svg => svg.replace(/#fff/, 'currentColor')
),
}
})
```
### Dynamic Import (Browser)
```ts
import presetIcons from '@unocss/preset-icons/browser'
presetIcons({
collections: {
carbon: () => import('@iconify-json/carbon/icons.json').then(i => i.default),
}
})
```
## Icon Customization
```ts
presetIcons({
customizations: {
// Transform SVG
transform(svg, collection, icon) {
return svg.replace(/#fff/, 'currentColor')
},
// Global sizing
customize(props) {
props.width = '2em'
props.height = '2em'
return props
},
// Per-collection
iconCustomizer(collection, icon, props) {
if (collection === 'mdi') {
props.width = '2em'
}
}
}
})
```
## CSS Directive
Use `icon()` in CSS (requires transformer-directives):
```css
.icon {
background-image: icon('i-carbon-sun');
}
.icon-colored {
background-image: icon('i-carbon-moon', '#fff');
}
```
## Accessibility
```html
<!-- With label -->
<a href="/profile" aria-label="Profile" class="i-ph:user-duotone"></a>
<!-- Decorative -->
<a href="/profile">
<span aria-hidden="true" class="i-ph:user-duotone"></span>
My Profile
</a>
```

name: preset-mini
description: Minimal preset with essential utilities for UnoCSS
---
# Preset Mini
The minimal preset with only essential rules and variants. Good starting point for custom presets.
## Installation
```ts
import { defineConfig, presetMini } from 'unocss'
export default defineConfig({
presets: [
presetMini(),
],
})
```
## What's Included
Subset of `preset-wind3` with essential utilities aligned to CSS properties:
- Basic spacing (margin, padding)
- Display (flex, grid, block, etc.)
- Positioning (absolute, relative, fixed)
- Sizing (width, height)
- Colors (text, background, border)
- Typography basics (font-size, font-weight)
- Borders and border-radius
- Basic transforms and transitions
## What's NOT Included
Opinionated or complex Tailwind utilities:
- `container`
- Complex animations
- Gradients
- Advanced typography
- Prose classes
## Use Cases
1. **Building custom presets** - Start with mini and add only what you need
2. **Minimal bundle size** - When you only need basic utilities
3. **Learning** - Understand UnoCSS core without Tailwind complexity
## Dark Mode
Same as preset-wind3:
```ts
presetMini({
dark: 'class' // or 'media'
})
```
```html
<div class="dark:bg-red:10" />
```
Class-based:
```css
.dark .dark\:bg-red\:10 {
background-color: rgb(248 113 113 / 0.1);
}
```
Media query:
```css
@media (prefers-color-scheme: dark) {
.dark\:bg-red\:10 {
background-color: rgb(248 113 113 / 0.1);
}
}
```
## CSS @layer Variant
Native CSS layer support:
```html
<div class="layer-foo:p4" />
```
```css
@layer foo {
.layer-foo\:p4 {
padding: 1rem;
}
}
```
## Theme Customization
```ts
presetMini({
theme: {
colors: {
veryCool: '#0000ff',
brand: {
primary: 'hsl(var(--hue, 217) 78% 51%)',
}
},
}
})
```
**Note:** `breakpoints` property is overridden, not merged.
## Options
```ts
presetMini({
// Dark mode: 'class' | 'media' | { light: string, dark: string }
dark: 'class',
// Generate [group=""] instead of .group for attributify
attributifyPseudo: false,
// CSS variable prefix (default: 'un-')
variablePrefix: 'un-',
// Utility prefix
prefix: undefined,
// Preflight generation: true | false | 'on-demand'
preflight: true,
})
```
## Building on Mini
Create custom preset extending mini:
```ts
import { presetMini } from 'unocss'
import type { Preset } from 'unocss'
export const myPreset: Preset = {
name: 'my-preset',
presets: [presetMini()],
rules: [
// Add custom rules
['card', { 'border-radius': '8px', 'box-shadow': '0 2px 8px rgba(0,0,0,0.1)' }],
],
shortcuts: {
'btn': 'px-4 py-2 rounded bg-blue-500 text-white',
},
}
```

name: preset-rem-to-px
description: Convert rem units to px for utilities
---
# Preset Rem to Px
Converts `rem` units to `px` in generated utilities.
## Installation
```ts
import { defineConfig, presetRemToPx, presetWind3 } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
presetRemToPx(),
],
})
```
## What It Does
Transforms all rem values to px:
```html
<div class="p-4">
```
Without preset:
```css
.p-4 { padding: 1rem; }
```
With preset:
```css
.p-4 { padding: 16px; }
```
## Use Cases
- Projects requiring pixel-perfect designs
- Environments where rem doesn't work well
- Consistency with pixel-based design systems
- Email templates (better compatibility)
## Options
```ts
presetRemToPx({
// Base font size for conversion (default: 16)
baseFontSize: 16,
})
```
Custom base:
```ts
presetRemToPx({
baseFontSize: 14, // 1rem = 14px
})
```
## With Preset Wind4
**Note:** `presetRemToPx` is not needed with `preset-wind4`. Use the built-in processor instead:
```ts
import { createRemToPxProcessor } from '@unocss/preset-wind4/utils'
export default defineConfig({
presets: [
presetWind4({
preflights: {
theme: {
process: createRemToPxProcessor(),
}
},
}),
],
// Also apply to utilities
postprocess: [createRemToPxProcessor()],
})
```
## Important Notes
- Order matters: place after the preset that generates rem values
- Affects all utilities with rem units
- Theme values in rem are also converted

name: preset-tagify
description: Use utilities as HTML tag names
---
# Preset Tagify
Use CSS utilities directly as HTML tag names.
## Installation
```ts
import { defineConfig, presetTagify } from 'unocss'
export default defineConfig({
presets: [
presetTagify(),
],
})
```
## Basic Usage
Instead of:
```html
<span class="text-red">red text</span>
<div class="flex">flexbox</div>
<span class="i-line-md-emoji-grin"></span>
```
Use tag names directly:
```html
<text-red>red text</text-red>
<flex>flexbox</flex>
<i-line-md-emoji-grin />
```
Works exactly the same!
## With Prefix
```ts
presetTagify({
prefix: 'un-'
})
```
```html
<!-- Matched -->
<un-flex></un-flex>
<!-- Not matched -->
<flex></flex>
```
## Extra Properties
Add CSS properties to matched tags:
```ts
presetTagify({
// Add display: inline-block to icons
extraProperties: matched => matched.startsWith('i-')
? { display: 'inline-block' }
: {},
})
```
Or apply to all:
```ts
presetTagify({
extraProperties: { display: 'block' }
})
```
## Options
```ts
presetTagify({
// Tag prefix
prefix: '',
// Excluded tags (won't be processed)
excludedTags: ['b', /^h\d+$/, 'table'],
// Extra CSS properties
extraProperties: {},
// Enable default extractor
defaultExtractor: true,
})
```
## Excluded Tags
By default, these tags are excluded:
- `b` (bold)
- `h1` through `h6` (headings)
- `table`
Add your own:
```ts
presetTagify({
excludedTags: [
'b',
/^h\d+$/,
'table',
'article', // Add custom exclusions
/^my-/, // Exclude tags starting with 'my-'
],
})
```
## Use Cases
- Quick prototyping
- Cleaner HTML for simple pages
- Icon embedding: `<i-carbon-sun />`
- Semantic-like styling: `<flex-center>`, `<text-red>`
## Limitations
- Custom element names must contain a hyphen (HTML spec)
- Some frameworks may not support all custom elements
- Utilities without hyphens need the prefix option

name: preset-wind3
description: Tailwind CSS / Windi CSS compatible preset for UnoCSS
---
# Preset Wind3
The Tailwind CSS / Windi CSS compatible preset. Most commonly used preset for UnoCSS.
## Installation
```ts
import { defineConfig, presetWind3 } from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
],
})
```
**Note:** `@unocss/preset-uno` and `@unocss/preset-wind` are deprecated and renamed to `@unocss/preset-wind3`.
## Features
- Full Tailwind CSS v3 compatibility
- Dark mode (`dark:`, `@dark:`)
- All responsive variants (`sm:`, `md:`, `lg:`, `xl:`, `2xl:`)
- All standard utilities (flex, grid, spacing, colors, typography, etc.)
- Animation support (includes Animate.css animations)
## Dark Mode
### Class-based (default)
```html
<div class="dark:bg-gray-800">
```
Generates: `.dark .dark\:bg-gray-800 { ... }`
### Media Query Based
```ts
presetWind3({
dark: 'media'
})
```
Generates: `@media (prefers-color-scheme: dark) { ... }`
### Opt-in Media Query
Use `@dark:` regardless of config:
```html
<div class="@dark:bg-gray-800">
```
## Options
```ts
presetWind3({
// Dark mode strategy
dark: 'class', // 'class' | 'media' | { light: '.light', dark: '.dark' }
// Generate pseudo selector as [group=""] instead of .group
attributifyPseudo: false,
// CSS custom properties prefix
variablePrefix: 'un-',
// Utils prefix
prefix: '',
// Generate preflight CSS
preflight: true, // true | false | 'on-demand'
// Mark all utilities as !important
important: false, // boolean | string (selector)
})
```
### Important Option
Make all utilities `!important`:
```ts
presetWind3({
important: true,
})
```
Or scope with selector to increase specificity without `!important`:
```ts
presetWind3({
important: '#app',
})
```
Output: `#app :is(.dark .dark\:bg-blue) { ... }`
## Differences from Tailwind CSS
### Quotes Not Supported
Template quotes don't work due to extractor:
```html
<!-- Won't work -->
<div class="before:content-['']">
<!-- Use shortcut instead -->
<div class="before:content-empty">
```
### Background Position
Use `position:` prefix for custom values:
```html
<!-- Tailwind -->
<div class="bg-[center_top_1rem]">
<!-- UnoCSS -->
<div class="bg-[position:center_top_1rem]">
```
### Animations
UnoCSS integrates Animate.css. Use `-alt` suffix for Animate.css versions when names conflict:
- `animate-bounce` - Tailwind version
- `animate-bounce-alt` - Animate.css version
Custom animations:
```ts
theme: {
animation: {
keyframes: {
custom: '{0%, 100% { opacity: 0; } 50% { opacity: 1; }}',
},
durations: {
custom: '1s',
},
timingFns: {
custom: 'ease-in-out',
},
counts: {
custom: 'infinite',
},
}
}
```
## Differences from Windi CSS
| Windi CSS | UnoCSS |
|-----------|--------|
| `<sm:p-1` | `lt-sm:p-1` |
| `@lg:p-1` | `at-lg:p-1` |
| `>xl:p-1` | `xl:p-1` |
Bracket syntax uses `_` instead of `,`:
```html
<!-- Windi CSS -->
<div class="grid-cols-[1fr,10px,max-content]">
<!-- UnoCSS -->
<div class="grid-cols-[1fr_10px_max-content]">
```
## Experimental: Media Hover
Addresses sticky hover on touch devices:
```html
<div class="@hover-text-red">
```
Generates:
```css
@media (hover: hover) and (pointer: fine) {
.\@hover-text-red:hover { ... }
}
```

# Preset Wind4
The Tailwind CSS v4 compatible preset. Enhances preset-wind3 with modern CSS features.
## Installation
```ts
import { defineConfig, presetWind4 } from 'unocss'
export default defineConfig({
presets: [
presetWind4(),
],
})
```
## Key Differences from Wind3
### Built-in CSS Reset
No need for `@unocss/reset` - reset is built-in:
```ts
// Remove these imports
import '@unocss/reset/tailwind.css' // ❌ Not needed
import '@unocss/reset/tailwind-compat.css' // ❌ Not needed
// Enable in config
presetWind4({
preflights: {
reset: true,
},
})
```
### OKLCH Color Model
Uses `oklch` for better color perception and contrast. Not compatible with `presetLegacyCompat`.
### Theme CSS Variables
Automatically generates CSS variables from theme:
```css
:root, :host {
--spacing: 0.25rem;
--font-sans: ui-sans-serif, system-ui, sans-serif;
--colors-black: #000;
--colors-white: #fff;
/* ... */
}
```
### @property CSS Rules
Uses `@property` for better browser optimization:
```css
@property --un-text-opacity {
syntax: '<percentage>';
inherits: false;
initial-value: 100%;
}
```
### Theme Key Changes
| preset-wind3 | preset-wind4 |
|--------------|--------------|
| `fontFamily` | `font` |
| `fontSize` | `text.fontSize` |
| `lineHeight` | `text.lineHeight` or `leading` |
| `letterSpacing` | `text.letterSpacing` or `tracking` |
| `borderRadius` | `radius` |
| `easing` | `ease` |
| `breakpoints` | `breakpoint` |
| `verticalBreakpoints` | `verticalBreakpoint` |
| `boxShadow` | `shadow` |
| `transitionProperty` | `property` |
| `container.maxWidth` | `containers.maxWidth` |
| Size properties (`width`, `height`, etc.) | Unified to `spacing` |
## Options
```ts
presetWind4({
preflights: {
// Built-in reset styles
reset: true,
// Theme CSS variables generation
theme: 'on-demand', // true | false | 'on-demand'
// @property CSS rules
property: true,
},
})
```
### Theme Variable Processing
Convert rem to px for theme variables:
```ts
import { createRemToPxProcessor } from '@unocss/preset-wind4/utils'
presetWind4({
preflights: {
theme: {
mode: 'on-demand',
process: createRemToPxProcessor(),
}
},
})
// Also apply to utilities
export default defineConfig({
postprocess: [createRemToPxProcessor()],
})
```
### Property Layer Customization
```ts
presetWind4({
preflights: {
property: {
// Custom parent wrapper
parent: '@layer custom-properties',
// Custom selector
selector: ':where(*, ::before, ::after)',
},
},
})
```
Remove `@supports` wrapper:
```ts
presetWind4({
preflights: {
property: {
parent: false,
},
},
})
```
## Generated Layers
| Layer | Description | Order |
|-------|-------------|-------|
| `properties` | CSS `@property` rules | -200 |
| `theme` | Theme CSS variables | -150 |
| `base` | Reset/preflight styles | -100 |
## Theme.defaults
Global default configuration for reset styles:
```ts
import type { Theme } from '@unocss/preset-wind4/theme'
const defaults: Theme['default'] = {
transition: {
duration: '150ms',
timingFunction: 'cubic-bezier(0.4, 0, 0.2, 1)',
},
font: {
family: 'var(--font-sans)',
featureSettings: 'var(--font-sans--font-feature-settings)',
variationSettings: 'var(--font-sans--font-variation-settings)',
},
monoFont: {
family: 'var(--font-mono)',
// ...
},
}
```
## Compatibility Notes
### presetRemToPx
Not needed - use built-in processor instead:
```ts
presetWind4({
preflights: {
theme: {
process: createRemToPxProcessor(),
}
},
})
```
### presetLegacyCompat
**Not compatible** with preset-wind4 due to `oklch` color model.
## Migration from Wind3
1. Update theme keys according to the table above
2. Remove `@unocss/reset` imports
3. Enable `preflights.reset: true`
4. Test color outputs (oklch vs rgb)
5. Update any custom theme extensions
```ts
// Before (wind3)
theme: {
fontFamily: { sans: 'Roboto' },
fontSize: { lg: '1.125rem' },
breakpoints: { sm: '640px' },
}
// After (wind4)
theme: {
font: { sans: 'Roboto' },
text: { lg: { fontSize: '1.125rem' } },
breakpoint: { sm: '640px' },
}
```
## When to Use Wind4
Choose **preset-wind4** when:
- Starting a new project
- Targeting modern browsers
- Want built-in reset and CSS variables
- Following Tailwind v4 conventions
Choose **preset-wind3** when:
- Need legacy browser support
- Migrating from Tailwind v3
- Using presetLegacyCompat
- Want stable, proven preset

name: transformer-attributify-jsx
description: Support valueless attributify in JSX/TSX
---
# Transformer Attributify JSX
Fixes valueless attributify mode in JSX where `<div foo>` becomes `<div foo={true}>`.
## The Problem
In JSX, valueless attributes are transformed:
```jsx
// You write
<div m-2 rounded text-teal-400 />
// JSX compiles to
<div m-2={true} rounded={true} text-teal-400={true} />
```
The `={true}` breaks UnoCSS attributify detection.
## Installation
```ts
import {
defineConfig,
presetAttributify,
transformerAttributifyJsx
} from 'unocss'
export default defineConfig({
presets: [
presetAttributify(),
],
transformers: [
transformerAttributifyJsx(),
],
})
```
## How It Works
The transformer converts JSX boolean attributes back to strings:
```jsx
// Input (after JSX compilation)
<div m-2={true} rounded={true} />
// Output (transformed)
<div m-2="" rounded="" />
```
Now UnoCSS can properly extract the attributify classes.
## Options
```ts
transformerAttributifyJsx({
// Only transform specific attributes
// Default: transforms all that match attributify patterns
blocklist: ['text', 'font'],
})
```
## When to Use
Required when using:
- React
- Preact
- Solid
- Any JSX-based framework
With valueless attributify syntax:
```jsx
// This needs the transformer
<div flex items-center gap-4 />
// This works without transformer (has values)
<div flex="~" items="center" gap="4" />
```
## Framework Setup
### React
```ts
// vite.config.ts
import React from '@vitejs/plugin-react'
import UnoCSS from 'unocss/vite'
export default {
plugins: [
UnoCSS(), // Must be before React
React(),
],
}
```
```ts
// uno.config.ts
import {
defineConfig,
presetAttributify,
presetWind3,
transformerAttributifyJsx
} from 'unocss'
export default defineConfig({
presets: [
presetWind3(),
presetAttributify(),
],
transformers: [
transformerAttributifyJsx(),
],
})
```
### Preact
Same as React, use `@preact/preset-vite` or `@prefresh/vite`.
### Solid
```ts
import UnoCSS from 'unocss/vite'
import solidPlugin from 'vite-plugin-solid'
export default {
plugins: [
UnoCSS(),
solidPlugin(),
],
}
```
## TypeScript Support
Add type declarations:
```ts
// shims.d.ts
import type { AttributifyAttributes } from '@unocss/preset-attributify'
declare module 'react' {
interface HTMLAttributes<T> extends AttributifyAttributes {}
}
```

```ts
transformerCompileClass({
// Custom trigger string (default: ':uno:')
trigger: ':uno:',
// Custom class prefix (default: 'uno-')
classPrefix: 'uno-',
// Hash function for class names
hashFn: (str) => /* custom hash */,
// Keep original classes alongside compiled
keepOriginal: false,
})
```
## Use Cases
- **Smaller HTML** - Reduce repetitive class strings
- **Obfuscation** - Hide utility class names in production
- **Performance** - Fewer class attributes to parse
## ESLint Integration
Enforce compile class usage across project:
```json
{
"rules": {
"@unocss/enforce-class-compile": "warn"
}
}
```
This rule:
- Warns when class attribute doesn't start with `:uno:`
- Auto-fixes by adding the prefix
Options:
```json
{
"rules": {
"@unocss/enforce-class-compile": ["warn", {
"prefix": ":uno:",
"enableFix": true
}]
}
}
```
## Combining with Other Transformers
```ts
export default defineConfig({
transformers: [
transformerVariantGroup(), // Process variant groups first
transformerDirectives(), // Then directives
transformerCompileClass(), // Compile last
],
})
```

# Transformer Directives
Enables `@apply`, `@screen`, `theme()`, and `icon()` directives in CSS.
## Installation
```ts
import { defineConfig, transformerDirectives } from 'unocss'
export default defineConfig({
transformers: [
transformerDirectives(),
],
})
```
## @apply
Apply utility classes in CSS:
```css
.custom-btn {
@apply py-2 px-4 font-semibold rounded-lg;
}
/* With variants - use quotes */
.custom-btn {
@apply 'hover:bg-blue-600 focus:ring-2';
}
```
### CSS Custom Property Alternative
For vanilla CSS compatibility:
```css
.custom-div {
--at-apply: text-center my-0 font-medium;
}
```
Supported aliases: `--at-apply`, `--uno-apply`, `--uno`
Configure aliases:
```ts
transformerDirectives({
applyVariable: ['--at-apply', '--uno-apply', '--uno'],
// or disable: applyVariable: false
})
```
## @screen
Create breakpoint media queries:
```css
.grid {
display: grid;
grid-template-columns: repeat(2, 1fr);
}
@screen sm {
.grid {
grid-template-columns: repeat(3, 1fr);
}
}
@screen lg {
.grid {
grid-template-columns: repeat(4, 1fr);
}
}
```
### Breakpoint Variants
```css
/* Less than breakpoint */
@screen lt-sm {
.item { display: none; }
}
/* At specific breakpoint only */
@screen at-md {
.item { width: 50%; }
}
```
## theme()
Access theme values in CSS:
```css
.btn-blue {
background-color: theme('colors.blue.500');
padding: theme('spacing.4');
border-radius: theme('borderRadius.lg');
}
```
Dot notation paths into your theme config.
## icon()
Convert icon utility to SVG (requires preset-icons):
```css
.icon-sun {
background-image: icon('i-carbon-sun');
}
/* With custom color */
.icon-moon {
background-image: icon('i-carbon-moon', '#fff');
}
/* Using theme color */
.icon-alert {
background-image: icon('i-carbon-warning', 'theme("colors.red.500")');
}
```
## Complete Example
```css
.card {
@apply rounded-lg shadow-md p-4;
background-color: theme('colors.white');
}
.card-header {
@apply 'font-bold text-lg border-b';
padding-bottom: theme('spacing.2');
}
@screen md {
.card {
@apply flex gap-4;
}
}
.card-icon {
background-image: icon('i-carbon-document');
@apply w-6 h-6;
}
```

# Transformer Variant Group
Enables shorthand syntax for grouping utilities with common prefixes.
## Installation
```ts
import { defineConfig, transformerVariantGroup } from 'unocss'
export default defineConfig({
transformers: [
transformerVariantGroup(),
],
})
```
## Usage
Group multiple utilities under one variant prefix using parentheses:
```html
<!-- Before transformation -->
<div class="hover:(bg-gray-400 font-medium) font-(light mono)" />
<!-- After transformation -->
<div class="hover:bg-gray-400 hover:font-medium font-light font-mono" />
```
## Examples
### Hover States
```html
<button class="hover:(bg-blue-600 text-white scale-105)">
Hover me
</button>
```
Expands to: `hover:bg-blue-600 hover:text-white hover:scale-105`
### Dark Mode
```html
<div class="dark:(bg-gray-800 text-white)">
Dark content
</div>
```
Expands to: `dark:bg-gray-800 dark:text-white`
### Responsive
```html
<div class="md:(flex items-center gap-4)">
Responsive flex
</div>
```
Expands to: `md:flex md:items-center md:gap-4`
### Nested Groups
```html
<div class="lg:hover:(bg-blue-500 text-white)">
Large screen hover
</div>
```
Expands to: `lg:hover:bg-blue-500 lg:hover:text-white`
### Multiple Prefixes
```html
<div class="text-(sm gray-600) font-(medium mono)">
Styled text
</div>
```
Expands to: `text-sm text-gray-600 font-medium font-mono`
## Key Points
- Use parentheses `()` to group utilities
- The prefix applies to all utilities inside the group
- Can be combined with any variant (hover, dark, responsive, etc.)
- Nesting is supported
- Works in class attributes and other extraction sources

name: advanced-api
description: Vite's JavaScript API for programmatic usage
---
# JavaScript API
Vite's APIs are fully typed. Use TypeScript or enable JS type checking for intellisense.
## `createServer`
Create a development server programmatically:
```ts
import { createServer } from 'vite'
const server = await createServer({
configFile: false,
root: __dirname,
server: {
port: 1337
}
})
await server.listen()
server.printUrls()
server.bindCLIShortcuts({ print: true })
```
### ViteDevServer Interface
```ts
interface ViteDevServer {
config: ResolvedConfig
middlewares: Connect.Server // Connect app for custom middleware
httpServer: http.Server | null // Node HTTP server
watcher: FSWatcher // Chokidar watcher
ws: WebSocketServer // WebSocket for HMR
moduleGraph: ModuleGraph // Module import relationships
// Transform without HTTP
transformRequest(url: string): Promise<TransformResult | null>
// Apply HTML transforms
transformIndexHtml(url: string, html: string): Promise<string>
// Load module for SSR
ssrLoadModule(url: string): Promise<Record<string, any>>
// Fix SSR error stack traces
ssrFixStacktrace(e: Error): void
// Control
listen(port?: number): Promise<ViteDevServer>
restart(): Promise<void>
close(): Promise<void>
}
```
## `build`
Build for production:
```ts
import { build } from 'vite'
await build({
root: './project',
base: '/foo/',
build: {
rolldownOptions: {
// ...
}
}
})
```
## `preview`
Preview production build locally:
```ts
import { preview } from 'vite'
const previewServer = await preview({
preview: {
port: 8080,
open: true
}
})
previewServer.printUrls()
```
## `resolveConfig`
Resolve config without starting server:
```ts
import { resolveConfig } from 'vite'
const config = await resolveConfig(
{ root: './project' },
'serve', // 'serve' | 'build'
'development' // default mode
)
```
## `mergeConfig`
Deep merge two configs:
```ts
import { mergeConfig } from 'vite'
const merged = mergeConfig(baseConfig, overrideConfig)
```
Merge callback config:
```ts
import { defineConfig, mergeConfig } from 'vite'
export default defineConfig((env) =>
mergeConfig(configAsCallback(env), configAsObject)
)
```
## `loadEnv`
Load .env files:
```ts
import { loadEnv } from 'vite'
// Load VITE_* vars
const env = loadEnv('development', process.cwd())
// Load all vars (empty prefix)
const allEnv = loadEnv('development', process.cwd(), '')
```
## `searchForWorkspaceRoot`
Find monorepo workspace root:
```ts
import { searchForWorkspaceRoot } from 'vite'
const workspaceRoot = searchForWorkspaceRoot(process.cwd())
```
## `normalizePath`
Normalize paths for cross-platform:
```ts
import { normalizePath } from 'vite'
normalizePath('foo\\bar') // 'foo/bar'
```
## `transformWithOxc`
Transform JS/TS with Oxc Transformer:
```ts
import { transformWithOxc } from 'vite'
const result = await transformWithOxc(
code,
'file.ts',
{ target: 'es2020' }
)
```
## `preprocessCSS`
Pre-process CSS files:
```ts
import { preprocessCSS, resolveConfig } from 'vite'
const config = await resolveConfig({}, 'serve')
const result = await preprocessCSS(code, 'styles.scss', config)
// result.code - plain CSS
// result.modules - CSS modules mapping
```
## `loadConfigFromFile`
Load config file manually:
```ts
import { loadConfigFromFile } from 'vite'
const result = await loadConfigFromFile(
{ command: 'serve', mode: 'development' },
'vite.config.ts'
)
// result.config, result.path, result.dependencies
```
## InlineConfig
Extends UserConfig with:
```ts
interface InlineConfig extends UserConfig {
configFile?: string | false // Config file path or false to skip
mode?: string
}
```

# Backend Integration
Integrate Vite with traditional backends (Rails, Laravel, etc.) for asset serving.
## Configuration
```ts
// vite.config.ts
export default defineConfig({
server: {
cors: {
origin: 'http://my-backend.example.com'
}
},
build: {
manifest: true, // Generate .vite/manifest.json
rolldownOptions: {
input: '/path/to/main.js' // Override HTML entry
}
}
})
```
Import polyfill in entry:
```ts
// main.js
import 'vite/modulepreload-polyfill'
```
## Development
Inject Vite client and entry in your backend template:
```html
<!-- Development only -->
<script type="module" src="http://localhost:5173/@vite/client"></script>
<script type="module" src="http://localhost:5173/main.js"></script>
```
### React Setup
Add before other scripts:
```html
<script type="module">
import RefreshRuntime from 'http://localhost:5173/@react-refresh'
RefreshRuntime.injectIntoGlobalHook(window)
window.$RefreshReg$ = () => {}
window.$RefreshSig$ = () => (type) => type
window.__vite_plugin_react_preamble_installed__ = true
</script>
```
### Asset Proxying
Either:
1. Proxy static asset requests to Vite
2. Set `server.origin`:
```ts
export default defineConfig({
server: {
origin: 'http://localhost:5173'
}
})
```
## Production
Build generates `.vite/manifest.json`:
```json
{
"views/foo.js": {
"file": "assets/foo-BRBmoGS9.js",
"src": "views/foo.js",
"isEntry": true,
"imports": ["_shared-B7PI925R.js"],
"css": ["assets/foo-5UjPuW-k.css"]
},
"_shared-B7PI925R.js": {
"file": "assets/shared-B7PI925R.js",
"css": ["assets/shared-ChJ_j-JJ.css"]
}
}
```
## Rendering Tags
For entry `views/foo.js`, render in this order:
```html
<!-- 1. Entry CSS -->
<link rel="stylesheet" href="/assets/foo-5UjPuW-k.css" />
<!-- 2. Imported chunks' CSS (recursive) -->
<link rel="stylesheet" href="/assets/shared-ChJ_j-JJ.css" />
<!-- 3. Entry script -->
<script type="module" src="/assets/foo-BRBmoGS9.js"></script>
<!-- 4. Optional: preload imports -->
<link rel="modulepreload" href="/assets/shared-B7PI925R.js" />
```
## Manifest Structure
```ts
interface ManifestChunk {
src?: string // Input file name
file: string // Output file name
css?: string[] // CSS files (JS chunks only)
assets?: string[] // Non-CSS assets (JS chunks only)
isEntry?: boolean // Is entry point
isDynamicEntry?: boolean // Is dynamic import
imports?: string[] // Static imports (manifest keys)
dynamicImports?: string[] // Dynamic imports (manifest keys)
}
```
## Processing Imports
Recursively collect all imported chunks:
```ts
function getImportedChunks(manifest, name) {
const seen = new Set()
const chunks = []
function collect(chunk) {
for (const file of chunk.imports ?? []) {
if (seen.has(file)) continue
seen.add(file)
const importee = manifest[file]
collect(importee)
chunks.push(importee)
}
}
collect(manifest[name])
return chunks
}
```

name: advanced-performance
description: Performance optimization tips for Vite dev server and builds
---
# Performance Optimization
## Browser Setup
- Use dev-only browser profile without extensions
- Disable "Disable Cache" in DevTools when using Vite
- Extensions can interfere with requests and slow startup
## Audit Plugin Performance
1. **Lazy load large dependencies** in plugins
2. **Avoid long operations** in `buildStart`, `config`, `configResolved`
3. **Optimize transform hooks** - check `id` extension before processing
Debug transform times:
```bash
vite --debug plugin-transform
```
Use [vite-plugin-inspect](https://github.com/antfu/vite-plugin-inspect) to inspect transforms.
## Profiling
```bash
vite --profile
# Visit site, press 'p + enter' to record .cpuprofile
# Open in https://www.speedscope.app
```
## Reduce Resolve Operations
Be explicit with extensions to avoid filesystem checks:
```ts
// Slow: checks .mjs, .js, .mts, .ts, .jsx, .tsx, .json
import Component from './Component'
// Fast: direct hit
import Component from './Component.tsx'
```
Enable TypeScript path resolution for explicit imports:
```json
{
"compilerOptions": {
"moduleResolution": "bundler",
"allowImportingTsExtensions": true
}
}
```
## Avoid Barrel Files
Barrel files (`index.js` re-exporting everything) cause all files to load:
```ts
// Slow: loads all utils
import { slash } from './utils'
// Fast: loads only slash.js
import { slash } from './utils/slash.js'
```
## Warm Up Frequently Used Files
Pre-transform files that are always loaded:
```ts
export default defineConfig({
server: {
warmup: {
clientFiles: [
'./src/components/BigComponent.vue',
'./src/utils/big-utils.js'
],
ssrFiles: ['./src/server/modules/*.js']
}
}
})
```
Find files to warm up:
```bash
vite --debug transform
```
## Use Native/Less Tooling
**Do less work:**
- CSS instead of Sass/Less (PostCSS has nesting)
- Don't transform SVGs to components - import as strings/URLs
- Skip Babel in `@vitejs/plugin-react` if not needed
**Use native tools:**
- Try Lightning CSS for faster CSS processing
```ts
export default defineConfig({
css: {
transformer: 'lightningcss'
}
})
```
## Server Options
### Open Browser Automatically
Triggers warmup of entry point:
```ts
export default defineConfig({
server: {
open: true
}
})
```
### Limit File Watching
```ts
export default defineConfig({
server: {
watch: {
ignored: ['**/large-folder/**']
}
}
})
```
## Build Performance
### Disable Reporting
Skip gzip size calculation for large projects:
```ts
export default defineConfig({
build: {
reportCompressedSize: false
}
})
```
### Sourcemaps
Disable if not needed:
```ts
export default defineConfig({
build: {
sourcemap: false
}
})
```

description: Creating Vite plugins, hooks, virtual modules, and client-server communication
---
# Plugin API
Vite plugins extend Rolldown's plugin interface with Vite-specific hooks.
## Basic Plugin Structure
```ts
export default function myPlugin(options = {}) {
return {
name: 'vite-plugin-my-plugin',
// Hooks...
}
}
```
## Naming Conventions
- Vite-only plugins: `vite-plugin-*`
- Rollup-compatible: `rollup-plugin-*`
- Framework-specific: `vite-plugin-vue-*`, `vite-plugin-react-*`
## Universal Hooks (from Rolldown)
Called on server start:
- `options` - Modify Rolldown options
- `buildStart` - Build starting
Called per module request:
- `resolveId` - Resolve import paths
- `load` - Load module content
- `transform` - Transform module code
Called on server close:
- `buildEnd`
- `closeBundle`
## Vite-Specific Hooks
### `config`
Modify config before resolution:
```ts
{
name: 'modify-config',
config(config, { command, mode }) {
if (command === 'build') {
return {
resolve: {
alias: { foo: 'bar' }
}
}
}
}
}
```
### `configResolved`
Access final resolved config:
```ts
{
name: 'read-config',
configResolved(config) {
this.config = config
}
}
```
### `configureServer`
Add dev server middleware:
```ts
{
name: 'configure-server',
configureServer(server) {
// Before Vite's middlewares
server.middlewares.use((req, res, next) => {
// Handle request
next()
})
// Return function to run after Vite's middlewares
return () => {
server.middlewares.use((req, res, next) => {
// Post middleware
})
}
}
}
```
### `transformIndexHtml`
Transform HTML files:
```ts
{
name: 'html-transform',
transformIndexHtml(html) {
return html.replace(/<title>(.*?)<\/title>/, '<title>New Title</title>')
}
}
```
Inject tags:
```ts
{
name: 'html-inject',
transformIndexHtml() {
return {
tags: [
{
tag: 'script',
attrs: { src: '/inject.js' },
injectTo: 'body' // 'head' | 'body' | 'head-prepend' | 'body-prepend'
}
]
}
}
}
```
### `handleHotUpdate`
Custom HMR handling:
```ts
{
name: 'custom-hmr',
handleHotUpdate({ file, server, modules }) {
if (file.endsWith('.custom')) {
server.ws.send({
type: 'custom',
event: 'custom-update',
data: { file }
})
return [] // Prevent default HMR
}
}
}
```
## Virtual Modules
Provide build-time information to source code:
```ts
export default function myPlugin() {
const virtualModuleId = 'virtual:my-module'
const resolvedId = '\0' + virtualModuleId
return {
name: 'virtual-module',
resolveId(id) {
if (id === virtualModuleId) {
return resolvedId
}
},
load(id) {
if (id === resolvedId) {
return `export const msg = "from virtual module"`
}
}
}
}
```
Usage:
```ts
import { msg } from 'virtual:my-module'
```
## Client-Server Communication
### Server to Client
```ts
{
configureServer(server) {
server.ws.on('connection', () => {
server.ws.send('my:greetings', { msg: 'hello' })
})
}
}
```
Client receives:
```ts
if (import.meta.hot) {
import.meta.hot.on('my:greetings', (data) => {
console.log(data.msg)
})
}
```
### Client to Server
```ts
// Client
if (import.meta.hot) {
import.meta.hot.send('my:from-client', { msg: 'Hey!' })
}
// Server (in plugin)
{
configureServer(server) {
server.ws.on('my:from-client', (data, client) => {
console.log(data.msg)
client.send('my:reply', { msg: 'Got it!' })
})
}
}
```
## Transform with Filtering
```ts
{
name: 'transform-js',
transform: {
filter: {
id: /\.js$/ // Only .js files
},
handler(code, id) {
return transformCode(code)
}
}
}
```
## Path Normalization
Use POSIX separators for cross-platform compatibility:
```ts
import { normalizePath } from 'vite'
normalizePath('foo\\bar') // 'foo/bar'
```

# Library Mode
Build browser-oriented libraries for distribution.
## Basic Configuration
```ts
import { resolve } from 'path'
import { defineConfig } from 'vite'
export default defineConfig({
build: {
lib: {
entry: resolve(__dirname, 'lib/main.js'),
name: 'MyLib', // Global variable name for UMD
fileName: 'my-lib' // Output filename (without extension)
},
rolldownOptions: {
external: ['vue'], // Don't bundle these
output: {
globals: {
vue: 'Vue' // Global var for externals in UMD
}
}
}
}
})
```
## Multiple Entry Points
```ts
export default defineConfig({
build: {
lib: {
entry: {
'my-lib': resolve(__dirname, 'lib/main.js'),
'secondary': resolve(__dirname, 'lib/secondary.js')
},
name: 'MyLib'
}
}
})
```
## Output Formats
Single entry defaults: `['es', 'umd']`
Multiple entries defaults: `['es', 'cjs']`
```ts
export default defineConfig({
build: {
lib: {
entry: resolve(__dirname, 'lib/main.js'),
formats: ['es', 'cjs', 'umd', 'iife']
}
}
})
```
## Custom File Names
```ts
export default defineConfig({
build: {
lib: {
entry: resolve(__dirname, 'lib/main.js'),
fileName: (format, entryName) => `${entryName}.${format}.js`,
cssFileName: 'styles' // For bundled CSS
}
}
})
```
## Package.json Configuration
### Single Entry
```json
{
"name": "my-lib",
"type": "module",
"files": ["dist"],
"main": "./dist/my-lib.umd.cjs",
"module": "./dist/my-lib.js",
"exports": {
".": {
"import": "./dist/my-lib.js",
"require": "./dist/my-lib.umd.cjs"
}
}
}
```
### Multiple Entries
```json
{
"name": "my-lib",
"type": "module",
"files": ["dist"],
"main": "./dist/my-lib.cjs",
"module": "./dist/my-lib.js",
"exports": {
".": {
"import": "./dist/my-lib.js",
"require": "./dist/my-lib.cjs"
},
"./secondary": {
"import": "./dist/secondary.js",
"require": "./dist/secondary.cjs"
}
}
}
```
### With CSS
```json
{
"exports": {
".": {
"import": "./dist/my-lib.js",
"require": "./dist/my-lib.umd.cjs"
},
"./style.css": "./dist/my-lib.css"
}
}
```
## Library Entry File
```ts
// lib/main.js
import Foo from './Foo.vue'
import Bar from './Bar.vue'
export { Foo, Bar }
```
## Environment Variables
In library mode:
- `import.meta.env.*` is statically replaced
- `process.env.*` is NOT replaced (consumers can change it)
To replace `process.env`:
```ts
export default defineConfig({
define: {
'process.env.NODE_ENV': '"production"'
}
})
```
## Notes
- `assetsInlineLimit` is ignored - assets always inlined
- `cssCodeSplit` defaults to `false`
- For non-browser libraries, consider using [tsdown](https://tsdown.dev/) or Rolldown directly

# Building for Production
## Basic Build
```bash
vite build
```
Uses `<root>/index.html` as entry point, outputs to `dist/`.
## Browser Compatibility
Default target: Baseline Widely Available browsers (Chrome 111+, Edge 111+, Firefox 114+, Safari 16.4+).
```ts
export default defineConfig({
build: {
target: 'es2020', // Or specific browsers
// target: ['chrome64', 'firefox78', 'safari12']
}
})
```
For legacy browsers:
```bash
npm add -D @vitejs/plugin-legacy
```
```ts
import legacy from '@vitejs/plugin-legacy'
export default defineConfig({
plugins: [
legacy({
targets: ['defaults', 'not IE 11']
})
]
})
```
## Output Configuration
```ts
export default defineConfig({
build: {
outDir: 'dist', // Output directory
assetsDir: 'assets', // Assets subdirectory
emptyOutDir: true, // Clear outDir before build
sourcemap: true, // Generate sourcemaps
// sourcemap: 'inline' | 'hidden'
}
})
```
## Public Base Path
For deploying under a subpath:
```ts
export default defineConfig({
base: '/my-app/'
})
```
Relative base (works anywhere):
```ts
export default defineConfig({
base: './'
})
```
Access in code:
```ts
const base = import.meta.env.BASE_URL
```
## Multi-Page App
```ts
import { resolve } from 'path'
export default defineConfig({
build: {
rolldownOptions: {
input: {
main: resolve(__dirname, 'index.html'),
nested: resolve(__dirname, 'nested/index.html')
}
}
}
})
```
## Minification
```ts
export default defineConfig({
build: {
minify: 'oxc', // Default, fastest
// minify: 'terser', // More options, slower
// minify: false, // Disable
terserOptions: { // If using terser
compress: {
drop_console: true
}
}
}
})
```
## Chunk Strategy
```ts
export default defineConfig({
build: {
rolldownOptions: {
output: {
codeSplitting: {
// Manual chunks configuration
}
}
},
chunkSizeWarningLimit: 500 // KB
}
})
```
## CSS Options
```ts
export default defineConfig({
build: {
cssCodeSplit: true, // CSS per async chunk
cssMinify: 'lightningcss', // or 'esbuild'
cssTarget: 'chrome61' // Different from JS target
}
})
```
## Asset Handling
```ts
export default defineConfig({
build: {
assetsInlineLimit: 4096, // Inline assets < 4KB as base64
copyPublicDir: true // Copy public/ to outDir
}
})
```
## Manifest
Generate manifest for backend integration:
```ts
export default defineConfig({
build: {
manifest: true // .vite/manifest.json
}
})
```
## Watch Mode
Rebuild on file changes:
```bash
vite build --watch
```
```ts
export default defineConfig({
build: {
watch: {} // Enable programmatically
}
})
```
## Load Error Handling
Handle dynamic import failures (e.g., after deployment):
```ts
window.addEventListener('vite:preloadError', (event) => {
window.location.reload()
})
```
## Build Optimizations (Automatic)
- **CSS code splitting** - CSS per async chunk
- **Preload directives** - `<link rel="modulepreload">`
- **Async chunk optimization** - Parallel fetching of dependencies
## License Generation
Generate license file for dependencies:
```ts
export default defineConfig({
build: {
license: true // .vite/license.md
}
})
```

description: Server-side rendering setup and configuration with Vite

# Server-Side Rendering (SSR)
Low-level API for framework authors. For applications, use higher-level tools from [Awesome Vite SSR](https://github.com/vitejs/awesome-vite#ssr).
## Project Structure
```
├── index.html
├── server.js # Express/Node server
└── src/
├── main.js # Universal app code
├── entry-client.js # Mounts app to DOM
└── entry-server.js # Renders app with SSR API
```
## index.html
```html
<!DOCTYPE html>
<html>
<body>
<div id="app"><!--ssr-outlet--></div>
<script type="module" src="/src/entry-client.js"></script>
</body>
</html>
```
## Development Server
```ts
// server.js
import express from 'express'
import { createServer as createViteServer } from 'vite'
async function createServer() {
const app = express()
const vite = await createViteServer({
server: { middlewareMode: true },
appType: 'custom'
})
app.use(vite.middlewares)
app.use('*all', async (req, res, next) => {
const url = req.originalUrl
try {
// 1. Read index.html
let template = fs.readFileSync(
path.resolve(__dirname, 'index.html'),
'utf-8'
)
// 2. Apply Vite transforms
template = await vite.transformIndexHtml(url, template)
// 3. Load server entry
const { render } = await vite.ssrLoadModule('/src/entry-server.js')
// 4. Render app HTML
const appHtml = await render(url)
// 5. Inject into template
const html = template.replace('<!--ssr-outlet-->', appHtml)
res.status(200).set({ 'Content-Type': 'text/html' }).end(html)
} catch (e) {
vite.ssrFixStacktrace(e)
next(e)
}
})
app.listen(5173)
}
createServer()
```
## Conditional Logic
```ts
if (import.meta.env.SSR) {
// Server-only code (tree-shaken on client)
}
```
## Production Build
```json
{
"scripts": {
"build:client": "vite build --outDir dist/client",
"build:server": "vite build --outDir dist/server --ssr src/entry-server.js"
}
}
```
### Production Server
```ts
// Differences from dev:
// 1. Use dist/client/index.html as template
// 2. Use import('./dist/server/entry-server.js') instead of ssrLoadModule
// 3. Serve static files from dist/client
```
## SSR Manifest
For preload directives:
```bash
vite build --outDir dist/client --ssrManifest
```
Generates `dist/client/.vite/ssr-manifest.json` with module-to-chunk mappings.
## SSR Externals
Dependencies are externalized by default. To transform with Vite:
```ts
export default defineConfig({
ssr: {
noExternal: ['package-that-needs-transform'],
external: ['package-to-externalize']
}
})
```
## SSR-specific Plugin Logic
```ts
export function mySSRPlugin() {
return {
name: 'my-ssr',
transform(code, id, options) {
if (options?.ssr) {
// SSR-specific transform
}
}
}
}
```
## SSR Target
```ts
export default defineConfig({
ssr: {
target: 'node', // Default
// target: 'webworker' // For edge runtimes
}
})
```
## SSR Bundle
Bundle all dependencies (for workers):
```ts
export default defineConfig({
ssr: {
noExternal: true // Bundle everything
}
})
```
## Resolve Conditions
```ts
export default defineConfig({
ssr: {
resolve: {
conditions: ['node'],
externalConditions: ['node']
}
}
})
```
## Pre-Rendering / SSG
Pre-render routes with known data into static HTML at build time.

# Vite Configuration
Vite automatically resolves a config file named `vite.config.*` in the project root.
## Basic Configuration
```ts
// vite.config.ts
import { defineConfig } from 'vite'
export default defineConfig({
// config options
})
```
Use `defineConfig` for TypeScript intellisense. Alternatively, use JSDoc annotations:
```js
/** @type {import('vite').UserConfig} */
export default {
// config options
}
```
## Conditional Config
Export a function to conditionally determine options based on command, mode, or build type:
```ts
import { defineConfig } from 'vite'
export default defineConfig(({ command, mode, isSsrBuild, isPreview }) => {
if (command === 'serve') {
// dev specific config
return {
define: {
__DEV__: true
}
}
} else {
// build specific config
return {
define: {
__DEV__: false
}
}
}
})
```
- `command` is `'serve'` during dev (`vite`, `vite dev`, `vite serve`) and `'build'` for production
- `mode` defaults to `'development'` for serve, `'production'` for build
## Async Config
```ts
import { defineConfig } from 'vite'
export default defineConfig(async ({ command, mode }) => {
const data = await fetchRemoteConfig()
return {
// config using fetched data
}
})
```
## Key Configuration Options
### Root and Base
```ts
export default defineConfig({
root: './src', // Project root directory (where index.html is)
base: '/my-app/', // Public base path for assets
publicDir: 'public', // Static assets directory
cacheDir: 'node_modules/.vite' // Cache directory
})
```
### Resolve Aliases
```ts
import { resolve } from 'path'
export default defineConfig({
resolve: {
alias: {
'@': resolve(__dirname, 'src'),
'~': resolve(__dirname, 'src/components')
},
// File extensions to try for imports without extension
extensions: ['.mjs', '.js', '.mts', '.ts', '.jsx', '.tsx', '.json']
}
})
```
### Define Global Constants
```ts
export default defineConfig({
define: {
__APP_VERSION__: JSON.stringify('1.0.0'),
__API_URL__: JSON.stringify('https://api.example.com')
}
})
```
Values must be JSON-serializable or a single identifier. Add TypeScript declarations:
```ts
// vite-env.d.ts
declare const __APP_VERSION__: string
declare const __API_URL__: string
```
### JSON Handling
```ts
export default defineConfig({
json: {
namedExports: true, // Support named imports from JSON
stringify: 'auto' // Stringify large JSON for performance
}
})
```
## Using Environment Variables in Config
Variables from `.env` files are NOT automatically available in config. Use `loadEnv`:
```ts
import { defineConfig, loadEnv } from 'vite'
export default defineConfig(({ mode }) => {
// Load env vars from .env files
const env = loadEnv(mode, process.cwd(), '')
return {
define: {
__APP_ENV__: JSON.stringify(env.APP_ENV)
},
server: {
port: env.APP_PORT ? Number(env.APP_PORT) : 5173
}
}
})
```
## Specifying Config File
```bash
vite --config my-config.ts
```
## Config Loading Methods
```bash
# Default: bundle with Rolldown (may have issues in monorepos)
vite
# Use module runner (no temp file, transforms on the fly)
vite --configLoader runner
# Use native runtime (requires Node.js with TypeScript support)
vite --configLoader native
```

description: Core Vite features including TypeScript, JSX, CSS, and HTML processing
---
# Core Features
## TypeScript
Vite supports `.ts` files out of the box with transpilation via Oxc Transformer (20-30x faster than tsc).
### Important: Transpile Only
Vite does NOT perform type checking. Run type checking separately:
```bash
# Production build
tsc --noEmit && vite build
# During development (separate process)
tsc --noEmit --watch
# Or use vite-plugin-checker for browser error reporting
```
### TypeScript Configuration
Required `tsconfig.json` settings:
```json
{
"compilerOptions": {
"isolatedModules": true,
"useDefineForClassFields": true,
"skipLibCheck": true
}
}
```
### Client Types
Add Vite's client types for `import.meta.env` and asset imports:
```json
{
"compilerOptions": {
"types": ["vite/client"]
}
}
```
This provides types for:
- Asset imports (`.svg`, `.png`, etc.)
- `import.meta.env` constants
- `import.meta.hot` HMR API
### Custom Type Overrides
Override default asset import types:
```ts
// vite-env-override.d.ts
declare module '*.svg' {
const content: React.FC<React.SVGProps<SVGElement>>
export default content
}
```
### Path Aliases with tsconfig
Enable tsconfig paths resolution:
```ts
// vite.config.ts
export default defineConfig({
resolve: {
tsconfigPaths: true
}
})
```
## JSX
`.jsx` and `.tsx` files are supported out of the box. Custom JSX configuration:
```ts
export default defineConfig({
oxc: {
jsx: {
runtime: 'classic', // or 'automatic'
pragma: 'h',
pragmaFrag: 'Fragment'
},
// Auto-inject JSX helpers
jsxInject: `import React from 'react'`
}
})
```
## HTML
`index.html` is the entry point, not tucked away in `public/`. Vite processes it as part of the module graph.
### Supported Elements
Vite processes these HTML element attributes:
- `<script type="module" src>`
- `<link href>` (stylesheets)
- `<img src>`, `<img srcset>`
- `<video src>`, `<video poster>`
- `<audio src>`
- `<source src>`, `<source srcset>`
- `<meta content>` (for og:image, twitter:image, etc.)
### Opt-out of Processing
```html
<script vite-ignore type="module" src="https://cdn.example.com/lib.js"></script>
```
### Multi-Page Apps
Access any HTML file by its path:
- `<root>/index.html` → `http://localhost:5173/`
- `<root>/about.html` → `http://localhost:5173/about.html`
- `<root>/blog/index.html` → `http://localhost:5173/blog/index.html`
## JSON
Direct import with named exports support:
```ts
// Import entire object
import json from './data.json'
// Named imports (tree-shakeable)
import { field } from './data.json'
```
## Framework Support
Official framework plugins:
| Framework | Plugin |
|-----------|--------|
| Vue 3 | `@vitejs/plugin-vue` |
| Vue 3 JSX | `@vitejs/plugin-vue-jsx` |
| React | `@vitejs/plugin-react` |
| React (SWC) | `@vitejs/plugin-react-swc` |
| React Server Components | `@vitejs/plugin-rsc` |
| Legacy browsers | `@vitejs/plugin-legacy` |
## Content Security Policy
Configure nonce for CSP:
```ts
export default defineConfig({
html: {
cspNonce: 'PLACEHOLDER' // Replace per-request
}
})
```

# Using Plugins
Vite extends Rolldown's plugin interface with extra Vite-specific options.
## Adding Plugins
Install and add to config:
```bash
npm add -D @vitejs/plugin-vue
```
```ts
// vite.config.ts
import vue from '@vitejs/plugin-vue'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [vue()]
})
```
## Plugin Arrays
Plugins can return arrays (for complex features):
```ts
// Framework plugin returning multiple plugins
export default function framework(config) {
return [
frameworkRefresh(config),
frameworkDevtools(config)
]
}
```
## Conditional Plugins
Falsy values are ignored:
```ts
export default defineConfig({
plugins: [
vue(),
process.env.ANALYZE && visualizer() // Only if ANALYZE is set
]
})
```
## Enforcing Plugin Order
Control when plugin runs relative to Vite core:
```ts
export default defineConfig({
plugins: [
{
...somePlugin(),
enforce: 'pre' // Before Vite core plugins
},
{
...anotherPlugin(),
enforce: 'post' // After Vite build plugins
}
]
})
```
**Order:**
1. Alias
2. Plugins with `enforce: 'pre'`
3. Vite core plugins
4. Plugins without enforce
5. Vite build plugins
6. Plugins with `enforce: 'post'`
7. Vite post-build plugins (minify, manifest)
## Conditional Application
Apply only during serve or build:
```ts
export default defineConfig({
plugins: [
{
...typescript2(),
apply: 'build' // Only during build
},
{
...devOnlyPlugin(),
apply: 'serve' // Only during dev
}
]
})
```
Function form for more control:
```ts
{
...myPlugin(),
apply(config, { command }) {
// Apply only on build but not for SSR
return command === 'build' && !config.build.ssr
}
}
```
## Finding Plugins
1. Check [Vite Features Guide](https://vite.dev/guide/features.html) - many use cases are built-in
2. Official plugins in [Vite Plugins](https://vite.dev/plugins/)
3. Community plugins in [awesome-vite](https://github.com/vitejs/awesome-vite#plugins)
4. Search npm for `vite-plugin-*` or `rollup-plugin-*`
## Official Plugins
| Plugin | Purpose |
|--------|---------|
| `@vitejs/plugin-vue` | Vue 3 SFC support |
| `@vitejs/plugin-vue-jsx` | Vue 3 JSX support |
| `@vitejs/plugin-react` | React with Babel/Oxc |
| `@vitejs/plugin-react-swc` | React with SWC |
| `@vitejs/plugin-rsc` | React Server Components |
| `@vitejs/plugin-legacy` | Legacy browser support |
## Rollup/Rolldown Plugin Compatibility
Many Rollup plugins work directly with Vite if they:
- Don't use `moduleParsed` hook
- Don't rely on Rolldown-specific options
- Don't have strong coupling between bundle and output phases
For build-only Rollup plugins:
```ts
export default defineConfig({
build: {
rolldownOptions: {
plugins: [rollupPluginForBuildOnly()]
}
}
})
```

description: Static asset handling in Vite including imports, public directory, and URL handling

# Static Asset Handling
## Importing Assets as URL
```ts
import imgUrl from './img.png'
document.getElementById('hero-img').src = imgUrl
// Dev: /src/img.png
// Build: /assets/img.2d8efhg.png
```
Common image, media, and font types are detected automatically.
## Import Queries
### Explicit URL Import
```ts
import workletURL from './worklet.js?url'
CSS.paintWorklet.addModule(workletURL)
```
### Import as String (Raw)
```ts
import shaderString from './shader.glsl?raw'
```
### Control Inlining
```ts
import imgUrl1 from './img.svg?no-inline' // Never inline
import imgUrl2 from './img.png?inline' // Always inline as base64
```
## Asset Inlining
Assets smaller than `assetsInlineLimit` (default 4KB) are inlined as base64:
```ts
export default defineConfig({
build: {
assetsInlineLimit: 4096, // 4KB
// Or use callback for fine control
assetsInlineLimit: (filePath) => {
return !filePath.endsWith('.svg')
}
}
})
```
## The `public` Directory
Files in `public/` are:
- Served at root path `/` during dev
- Copied as-is to `dist/` root during build
- Not processed or hashed
```
public/
favicon.ico → /favicon.ico
robots.txt → /robots.txt
```
Reference with absolute paths in source:
```html
<img src="/icon.png" />
```
Configure directory:
```ts
export default defineConfig({
publicDir: 'static' // or false to disable
})
```
## Extending Asset Types
```ts
export default defineConfig({
assetsInclude: ['**/*.gltf', '**/*.hdr']
})
```
## Dynamic URLs with import.meta.url
```ts
// Works natively in modern browsers
const imgUrl = new URL('./img.png', import.meta.url).href
// Dynamic pattern (limited)
function getImageUrl(name) {
return new URL(`./dir/${name}.png`, import.meta.url).href
}
```
**Limitations:**
- URL string must be static for build analysis
- Does not work with SSR (different semantics in Node.js vs browser)
## TypeScript Support
Add `vite/client` to types for asset import recognition:
```json
{
"compilerOptions": {
"types": ["vite/client"]
}
}
```
## URL Handling in CSS
```css
.hero {
background: url('./img.png'); /* Processed and rebased */
}
```

# CSS Handling
Vite provides rich CSS support with HMR, `@import` inlining, and automatic URL rebasing.
## Basic CSS Import
```ts
import './styles.css' // Injected into page with HMR support
```
## CSS Modules
Files ending with `.module.css` are treated as CSS modules:
```css
/* example.module.css */
.red {
color: red;
}
```
```ts
import classes from './example.module.css'
element.className = classes.red
```
### Named Imports with camelCase
```ts
// vite.config.ts
export default defineConfig({
css: {
modules: {
localsConvention: 'camelCaseOnly'
}
}
})
```
```ts
// .apply-color -> applyColor
import { applyColor } from './example.module.css'
```
## CSS Pre-processors
Install the pre-processor, no Vite plugin needed:
```bash
# Sass (sass-embedded recommended for performance)
npm add -D sass-embedded
# Less
npm add -D less
# Stylus
npm add -D stylus
```
Use by file extension:
```ts
import './styles.scss'
import './styles.less'
import './styles.styl'
```
### Pre-processor Options
```ts
export default defineConfig({
css: {
preprocessorOptions: {
scss: {
additionalData: `$injectedColor: orange;`,
importers: [/* ... */]
},
less: {
math: 'parens-division'
}
},
preprocessorMaxWorkers: true // Use multiple threads
}
})
```
### Combined with CSS Modules
```ts
import styles from './component.module.scss'
```
## PostCSS
Automatically applied if `postcss.config.js` exists:
```js
// postcss.config.js
export default {
plugins: [
require('postcss-nesting'),
require('autoprefixer')
]
}
```
Or configure inline:
```ts
export default defineConfig({
css: {
postcss: {
plugins: [
postcssNesting(),
autoprefixer()
]
}
}
})
```
## Lightning CSS
Experimental faster CSS processing:
```bash
npm add -D lightningcss
```
```ts
export default defineConfig({
css: {
transformer: 'lightningcss',
lightningcss: {
targets: {
chrome: 111
},
cssModules: {
// Lightning CSS modules config
}
}
}
})
```
Use Lightning CSS for minification only:
```ts
export default defineConfig({
build: {
cssMinify: 'lightningcss'
}
})
```
## Disable CSS Injection
Import CSS as string without injecting:
```ts
import styles from './styles.css?inline' // Returns CSS string, not injected
```
## Source Maps
Enable CSS source maps in development:
```ts
export default defineConfig({
css: {
devSourcemap: true
}
})
```
## CSS Code Splitting
By default, CSS is extracted per async chunk. Disable to get single CSS file:
```ts
export default defineConfig({
build: {
cssCodeSplit: false // Single CSS file for entire app
}
})
```
## CSS Target
Set different browser target for CSS:
```ts
export default defineConfig({
build: {
cssTarget: 'chrome61' // For Android WeChat WebView
}
})
```
## @import and URL Handling
- `@import` statements are inlined automatically
- Vite aliases work in `@import`
- `url()` references are rebased for correctness
- Works across Sass/Less files in different directories

# Dependency Pre-Bundling
Vite pre-bundles dependencies on first run for faster dev server startup.
## Why Pre-Bundling
1. **CommonJS/UMD to ESM** - Convert non-ESM dependencies
2. **Performance** - Bundle many internal modules into single file (e.g., lodash-es has 600+ modules)
```ts
// Works thanks to smart import analysis
import React, { useState } from 'react'
```
## Automatic Discovery
Vite crawls source code to find bare imports and pre-bundles them with Rolldown.
New dependencies discovered after server start trigger re-bundling.
## Including Dependencies
Force pre-bundling for dependencies not auto-discovered:
```ts
export default defineConfig({
optimizeDeps: {
include: [
'some-package',
'another-package/nested' // Deep imports
]
}
})
```
**When to include:**
- Dynamically imported (via plugin transform)
- Large dependencies with many internal modules
- CommonJS dependencies
## Excluding Dependencies
Skip pre-bundling for small ESM-only dependencies:
```ts
export default defineConfig({
optimizeDeps: {
exclude: ['small-esm-dep']
}
})
```
## Monorepo Linked Dependencies
Linked packages are treated as source code by default. If not ESM:
```ts
export default defineConfig({
optimizeDeps: {
include: ['linked-dep']
}
})
```
Restart with `--force` after making changes to linked deps.
## Custom Rolldown Options
```ts
export default defineConfig({
optimizeDeps: {
rolldownOptions: {
plugins: [/* Rolldown plugins */],
// Other Rolldown options
}
}
})
```
## Caching
### File System Cache
Located in `node_modules/.vite`. Re-runs when:
- Package lockfile changes (`package-lock.json`, `pnpm-lock.yaml`, etc.)
- Patches folder modified
- `vite.config.js` changes
- `NODE_ENV` changes
Force re-bundle:
```bash
vite --force
# Or delete node_modules/.vite
```
### Browser Cache
Pre-bundled deps are cached with `max-age=31536000,immutable`.
To debug dependencies with local edits:
1. Disable cache in browser DevTools Network tab
2. Restart Vite with `--force`
3. Reload page
## Entries
Specify custom entry points for discovery:
```ts
export default defineConfig({
optimizeDeps: {
entries: [
'src/main.ts',
'src/other-entry.ts'
]
}
})
```
By default, all HTML files are used as entries.
## esbuildOptions (Deprecated)
Use `rolldownOptions` instead:
```ts
export default defineConfig({
optimizeDeps: {
// Deprecated
esbuildOptions: {},
// Use instead
rolldownOptions: {}
}
})
```

name: features-env
description: Environment variables, .env files, and modes in Vite
---
# Environment Variables and Modes
## Built-in Constants
Available via `import.meta.env`:
| Constant | Description |
|----------|-------------|
| `import.meta.env.MODE` | App mode (`'development'` or `'production'`) |
| `import.meta.env.BASE_URL` | Base URL from `base` config |
| `import.meta.env.PROD` | `true` in production |
| `import.meta.env.DEV` | `true` in development |
| `import.meta.env.SSR` | `true` in server-side rendering |
```ts
if (import.meta.env.DEV) {
console.log('Development mode')
// Tree-shaken in production
}
```
## Custom Environment Variables
Only variables prefixed with `VITE_` are exposed to client code:
```bash
# .env
VITE_API_URL=https://api.example.com
DB_PASSWORD=secret # NOT exposed to client
```
```ts
console.log(import.meta.env.VITE_API_URL) // "https://api.example.com"
console.log(import.meta.env.DB_PASSWORD) // undefined
```
### Custom Prefix
```ts
export default defineConfig({
envPrefix: ['VITE_', 'APP_'] // Expose VITE_* and APP_*
})
```
## .env Files
Load order (later has higher priority):
```
.env # Always loaded
.env.local # Always loaded, gitignored
.env.[mode] # Only in specified mode
.env.[mode].local # Only in specified mode, gitignored
```
### Variable Expansion
```bash
# .env
KEY=123
EXPANDED=test$KEY # test123
ESCAPED=test\$foo # test$foo (escaped)
```
## Modes
```bash
# Development mode (default for dev)
vite
# Production mode (default for build)
vite build
# Custom mode
vite build --mode staging
```
Create mode-specific env file:
```bash
# .env.staging
VITE_APP_TITLE=My App (staging)
NODE_ENV=production # Still production build
```
### NODE_ENV vs Mode
| Command | NODE_ENV | Mode |
|---------|----------|------|
| `vite build` | `production` | `production` |
| `vite build --mode development` | `production` | `development` |
| `NODE_ENV=development vite build` | `development` | `production` |
## TypeScript IntelliSense
Create type declarations for custom env variables:
```ts
// vite-env.d.ts
interface ImportMetaEnv {
readonly VITE_APP_TITLE: string
readonly VITE_API_URL: string
}
interface ImportMeta {
readonly env: ImportMetaEnv
}
```
For strict typing (disallow unknown keys):
```ts
interface ViteTypeOptions {
strictImportMetaEnv: unknown
}
```
## HTML Replacement
Use `%VARIABLE%` syntax in HTML:
```html
<title>%VITE_APP_TITLE%</title>
<p>Mode: %MODE%</p>
```
Non-existent variables are left as-is (not replaced with `undefined`).
## Loading Env in Config
Env vars are NOT available in `vite.config.ts` automatically:
```ts
import { defineConfig, loadEnv } from 'vite'
export default defineConfig(({ mode }) => {
const env = loadEnv(mode, process.cwd(), '') // '' loads all vars
return {
define: {
__APP_ENV__: JSON.stringify(env.APP_ENV)
}
}
})
```
## Security Notes
- Add `*.local` to `.gitignore`
- `VITE_*` variables end up in client bundle - no secrets
- Never set `envPrefix` to `''` (exposes everything)

name: features-glob-import
description: Vite's import.meta.glob for batch importing modules and dynamic imports
---
# Glob Import
## Basic Usage
Import multiple modules using glob patterns:
```ts
const modules = import.meta.glob('./dir/*.js')
// Transformed to:
// {
// './dir/foo.js': () => import('./dir/foo.js'),
// './dir/bar.js': () => import('./dir/bar.js'),
// }
```
Iterate and load:
```ts
for (const path in modules) {
modules[path]().then((mod) => {
console.log(path, mod)
})
}
```
## Eager Loading
Load all modules immediately (no dynamic import):
```ts
const modules = import.meta.glob('./dir/*.js', { eager: true })
// Transformed to:
// import * as __glob_0 from './dir/foo.js'
// import * as __glob_1 from './dir/bar.js'
// const modules = {
// './dir/foo.js': __glob_0,
// './dir/bar.js': __glob_1,
// }
```
## Multiple Patterns
```ts
const modules = import.meta.glob([
'./dir/*.js',
'./another/*.js'
])
```
## Negative Patterns
Exclude files with `!` prefix:
```ts
const modules = import.meta.glob([
'./dir/*.js',
'!**/bar.js' // Exclude bar.js
])
```
## Named Imports
Import specific exports for tree-shaking:
```ts
const modules = import.meta.glob('./dir/*.js', {
import: 'setup'
})
// './dir/foo.js': () => import('./dir/foo.js').then(m => m.setup)
```
Import default export:
```ts
const modules = import.meta.glob('./dir/*.js', {
import: 'default',
eager: true
})
```
## Custom Queries
Import as raw strings or URLs:
```ts
const moduleStrings = import.meta.glob('./dir/*.svg', {
query: '?raw',
import: 'default'
})
const moduleUrls = import.meta.glob('./dir/*.svg', {
query: '?url',
import: 'default'
})
```
Custom queries for plugins:
```ts
const modules = import.meta.glob('./dir/*.js', {
query: { foo: 'bar', bar: true }
})
```
## Base Path
Change the base path for imports:
```ts
const modules = import.meta.glob('./**/*.js', {
base: './base'
})
// Keys: './dir/foo.js'
// Imports: './base/dir/foo.js'
```
## Important Caveats
1. **Vite-only feature** - Not a web standard
2. **Patterns must be literals** - Cannot use variables
3. **Relative or absolute** - Must start with `./`, `/`, or use an alias
4. **Glob matching** - Uses [tinyglobby](https://github.com/SuperchupuDev/tinyglobby)
## Dynamic Import with Variables
Limited dynamic import support:
```ts
const module = await import(`./dir/${file}.js`)
```
**Rules:**
- Must start with `./` or `../`
- Must end with file extension
- Variable represents only one level (no `foo/bar`)
- Own directory needs filename pattern: `./prefix-${foo}.js` not `./${foo}.js`
## Practical Example: Loading Route Components
```ts
// Lazy load all page components
const pages = import.meta.glob('./pages/*.vue')
const routes = Object.keys(pages).map((path) => {
const name = path.match(/\.\/pages\/(.*)\.vue$/)[1]
return {
path: `/${name.toLowerCase()}`,
component: pages[path] // Lazy loaded
}
})
```

name: features-hmr
description: Vite's Hot Module Replacement (HMR) client API
---
# HMR API
The HMR API is exposed via `import.meta.hot`. Primarily for framework and tooling authors.
## Conditional Guard
Always guard HMR code for tree-shaking in production:
```ts
if (import.meta.hot) {
// HMR code
}
```
## TypeScript Support
Add to `tsconfig.json`:
```json
{
"compilerOptions": {
"types": ["vite/client"]
}
}
```
## Self-Accepting Module
Module handles its own updates:
```ts
export const count = 1
if (import.meta.hot) {
import.meta.hot.accept((newModule) => {
if (newModule) {
console.log('updated: count is now', newModule.count)
}
})
}
```
## Accept Dependency Updates
React to changes in dependencies without self-reload:
```ts
import { foo } from './foo.js'
foo()
if (import.meta.hot) {
// Single dependency
import.meta.hot.accept('./foo.js', (newFoo) => {
newFoo?.foo()
})
// Multiple dependencies
import.meta.hot.accept(
['./foo.js', './bar.js'],
([newFooModule, newBarModule]) => {
// Handle updates
}
)
}
```
## Cleanup on Update
Clean up side effects before module is replaced:
```ts
function setupSideEffect() {
const interval = setInterval(() => {}, 1000)
return interval
}
const interval = setupSideEffect()
if (import.meta.hot) {
import.meta.hot.dispose((data) => {
clearInterval(interval)
})
}
```
## Prune Callback
Called when module is no longer imported:
```ts
if (import.meta.hot) {
import.meta.hot.prune((data) => {
// Cleanup when module is removed from page
})
}
```
## Persistent Data
Pass data between module instances:
```ts
if (import.meta.hot) {
// Mutate properties, don't reassign data itself
import.meta.hot.data.count = (import.meta.hot.data.count || 0) + 1
}
```
## Invalidate
Force propagation to importers:
```ts
if (import.meta.hot) {
import.meta.hot.accept((module) => {
if (cannotHandleUpdate(module)) {
import.meta.hot.invalidate() // Propagate to importers
}
})
}
```
## HMR Events
Listen to built-in events:
```ts
if (import.meta.hot) {
import.meta.hot.on('vite:beforeUpdate', (payload) => {
console.log('Update incoming')
})
import.meta.hot.on('vite:afterUpdate', (payload) => {
console.log('Update applied')
})
import.meta.hot.on('vite:beforeFullReload', () => {
console.log('Full reload')
})
import.meta.hot.on('vite:error', (error) => {
console.error('HMR error', error)
})
import.meta.hot.on('vite:ws:connect', () => {
console.log('WebSocket connected')
})
import.meta.hot.on('vite:ws:disconnect', () => {
console.log('WebSocket disconnected')
})
}
```
## Custom Events
Send events to server:
```ts
// Client
if (import.meta.hot) {
import.meta.hot.send('my:event', { msg: 'Hello from client' })
}
```
Receive from server:
```ts
// Client
if (import.meta.hot) {
import.meta.hot.on('my:response', (data) => {
console.log(data.msg)
})
}
```
## TypeScript for Custom Events
```ts
// events.d.ts
import 'vite/types/customEvent.d.ts'
declare module 'vite/types/customEvent.d.ts' {
interface CustomEventMap {
'my:event': { msg: string }
'my:response': { msg: string }
}
}
```

name: features-workers
description: Web Worker support in Vite
---
# Web Workers
## Constructor Syntax (Recommended)
Standard Web Worker creation:
```ts
const worker = new Worker(new URL('./worker.js', import.meta.url))
```
Module worker:
```ts
const worker = new Worker(new URL('./worker.js', import.meta.url), {
type: 'module'
})
```
Shared Worker:
```ts
const sharedWorker = new SharedWorker(
new URL('./shared-worker.js', import.meta.url)
)
```
**Note:** The `new URL()` must be used directly inside `new Worker()` for detection.
## Query Suffix Syntax
Import with `?worker` suffix:
```ts
import MyWorker from './worker?worker'
const worker = new MyWorker()
```
Shared worker:
```ts
import MySharedWorker from './worker?sharedworker'
const worker = new MySharedWorker()
```
### Inline Worker
Inline as base64 string (no separate chunk):
```ts
import MyWorker from './worker?worker&inline'
const worker = new MyWorker()
```
### Worker URL Only
Get URL instead of constructor:
```ts
import workerUrl from './worker?worker&url'
```
## Worker Script
Workers can use ESM `import` statements:
```ts
// worker.js
import { heavyComputation } from './utils'
self.onmessage = (e) => {
const result = heavyComputation(e.data)
self.postMessage(result)
}
```
## Worker Options
Configure worker bundling:
```ts
// vite.config.ts
export default defineConfig({
worker: {
format: 'es', // or 'iife'
plugins: () => [/* worker-specific plugins */],
rollupOptions: {
// Rollup options for worker bundle
}
}
})
```
## WebAssembly in Workers
```ts
// worker.js
import init from './module.wasm?init'
init().then((instance) => {
instance.exports.compute()
})
```

title: Use Class-based Animations for Non-Enter/Leave Effects
impact: LOW
impactDescription: Class-based animations are simpler and more performant for elements that remain in the DOM
type: best-practice
tags: [vue3, animation, css, class-binding, state]
---
# Use Class-based Animations for Non-Enter/Leave Effects
**Impact: LOW** - For animations on elements that are not entering or leaving the DOM, use CSS class-based animations triggered by Vue's reactive state. This is simpler than `<Transition>` and more appropriate for feedback animations like shake, pulse, or highlight effects.
## Task Checklist
- [ ] Use class-based animations for elements staying in the DOM
- [ ] Use `<Transition>` only for enter/leave animations
- [ ] Combine CSS animations with Vue's class bindings (`:class`)
- [ ] Consider using `setTimeout` to auto-remove animation classes
**When to Use Class-based Animations:**
- User feedback (shake on error, pulse on success)
- Attention-grabbing effects (highlight changes)
- Hover/focus states that need more than CSS transitions
- Any animation where the element stays mounted
**When to Use Transition Component:**
- Elements entering/leaving the DOM (v-if/v-show)
- Route transitions
- List item additions/removals
## Basic Pattern
```vue
<template>
<div :class="{ shake: showError }">
<button @click="submitForm">Submit</button>
<span v-if="showError">This feature is disabled!</span>
</div>
</template>
<script setup>
import { ref } from 'vue'
const showError = ref(false)
function submitForm() {
if (!isValid()) {
// Trigger shake animation
showError.value = true
// Auto-remove class after animation completes
setTimeout(() => {
showError.value = false
}, 820) // Match animation duration
}
}
</script>
<style>
.shake {
animation: shake 0.82s cubic-bezier(0.36, 0.07, 0.19, 0.97) both;
transform: translate3d(0, 0, 0); /* Enable GPU acceleration */
}
@keyframes shake {
10%, 90% { transform: translate3d(-1px, 0, 0); }
20%, 80% { transform: translate3d(2px, 0, 0); }
30%, 50%, 70% { transform: translate3d(-4px, 0, 0); }
40%, 60% { transform: translate3d(4px, 0, 0); }
}
</style>
```
## Common Animation Patterns
### Pulse on Success
```vue
<template>
<button
@click="save"
:class="{ pulse: saved }"
>
{{ saved ? 'Saved!' : 'Save' }}
</button>
</template>
<script setup>
import { ref } from 'vue'
const saved = ref(false)
async function save() {
await saveData()
saved.value = true
setTimeout(() => saved.value = false, 1000)
}
</script>
<style>
.pulse {
animation: pulse 0.5s ease-in-out;
}
@keyframes pulse {
0%, 100% { transform: scale(1); }
50% { transform: scale(1.05); }
}
</style>
```
### Highlight on Change
```vue
<template>
<div
:class="{ highlight: justUpdated }"
>
Value: {{ value }}
</div>
</template>
<script setup>
import { ref, watch } from 'vue'
const value = ref(0)
const justUpdated = ref(false)
watch(value, () => {
justUpdated.value = true
setTimeout(() => justUpdated.value = false, 1000)
})
</script>
<style>
.highlight {
animation: highlight 1s ease-out;
}
@keyframes highlight {
0% { background-color: yellow; }
100% { background-color: transparent; }
}
</style>
```
### Bounce Attention
```vue
<template>
<div
:class="{ bounce: needsAttention }"
@animationend="needsAttention = false"
>
<BellIcon />
</div>
</template>
<script setup>
import { ref } from 'vue'
const needsAttention = ref(false)
function notifyUser() {
needsAttention.value = true
// No setTimeout needed - using animationend event
}
</script>
<style>
.bounce {
animation: bounce 0.5s ease;
}
@keyframes bounce {
0%, 100% { transform: translateY(0); }
50% { transform: translateY(-10px); }
}
</style>
```
## Using animationend Event
Instead of `setTimeout`, use the `animationend` event for cleaner code:
```vue
<template>
<div
:class="{ animate: isAnimating }"
@animationend="isAnimating = false"
>
Content
</div>
</template>
<script setup>
import { ref } from 'vue'
const isAnimating = ref(false)
function triggerAnimation() {
isAnimating.value = true
// Class is automatically removed when animation ends
}
</script>
```
## Composable for Reusable Animations
```javascript
// composables/useAnimation.js
import { ref } from 'vue'
export function useAnimation(duration = 500) {
const isAnimating = ref(false)
function trigger() {
isAnimating.value = true
setTimeout(() => {
isAnimating.value = false
}, duration)
}
return {
isAnimating,
trigger
}
}
```
```vue
<script setup>
import { useAnimation } from '@/composables/useAnimation'
const shake = useAnimation(820)
const pulse = useAnimation(500)
</script>
<template>
<button
:class="{ shake: shake.isAnimating.value }"
@click="shake.trigger()"
>
Shake me
</button>
<button
:class="{ pulse: pulse.isAnimating.value }"
@click="pulse.trigger()"
>
Pulse me
</button>
</template>
```

title: Use Key Attribute to Force Re-render Animations

# Use Key Attribute to Force Re-render Animations
**Impact: MEDIUM** - Vue optimizes performance by reusing DOM elements when possible. However, this optimization can prevent animation libraries (like AutoAnimate) from detecting changes, because the element is updated in place rather than re-created. Adding a `:key` attribute forces Vue to treat changed elements as new, triggering proper animations.
## Task Checklist
- [ ] Add `:key` to elements that should animate when their content changes
- [ ] Use unique, changing values for keys (not indices)
- [ ] For route transitions, add `:key="$route.fullPath"` to `<router-view>`
- [ ] Apply `v-auto-animate` to the parent element of keyed children
**Problematic Code:**
```vue
<template>
<!-- BAD: Text changes but no animation occurs -->
<div v-auto-animate>
<p>{{ message }}</p> <!-- No key - element is reused -->
</div>
<!-- BAD: Image source changes but no animation -->
<div v-auto-animate>
<img :src="imageUrl" /> <!-- No key - element is reused -->
</div>
<!-- BAD: Route changes don't animate -->
<router-view v-auto-animate /> <!-- No key -->
</template>
<script setup>
import { ref } from 'vue'
const message = ref('Hello')
const imageUrl = ref('/images/photo1.jpg')
// Changing these won't trigger animations because
// Vue updates the existing elements rather than replacing them
</script>
```
**Correct Code:**
```vue
<template>
<!-- GOOD: Key forces re-render, triggering animation -->
<div v-auto-animate>
<p :key="message">{{ message }}</p>
</div>
<!-- GOOD: Image animates when source changes -->
<div v-auto-animate>
<img :key="imageUrl" :src="imageUrl" />
</div>
<!-- GOOD: Route changes animate properly -->
<router-view :key="$route.fullPath" v-auto-animate />
</template>
<script setup>
import { ref } from 'vue'
const message = ref('Hello')
const imageUrl = ref('/images/photo1.jpg')
// Now changing these will trigger animations
function updateMessage() {
message.value = 'World' // Triggers enter animation for new <p>
}
</script>
```
## Why This Works
When Vue sees a `:key` change:
1. It considers the old element and new element as different
2. The old element is removed (triggering leave animation)
3. A new element is created (triggering enter animation)
Without `:key`:
1. Vue sees the same element type in the same position
2. It updates the element's properties in place
3. No DOM addition/removal occurs, so no animation triggers
## Common Use Cases
### Animating Text Content Changes
```vue
<template>
<div v-auto-animate>
<h1 :key="title">{{ title }}</h1>
<p :key="description">{{ description }}</p>
</div>
</template>
```
### Animating Dynamic Components
```vue
<template>
<div v-auto-animate>
<component :is="currentComponent" :key="currentComponent" />
</div>
</template>
```
### Animating Route Transitions
```vue
<template>
<router-view v-slot="{ Component, route }">
<div v-auto-animate>
<component :is="Component" :key="route.fullPath" />
</div>
</router-view>
</template>
```
## With Vue's Built-in Transition
The same principle applies to Vue's `<Transition>` component:
```vue
<template>
<!-- GOOD: Key triggers transition on content change -->
<Transition name="fade" mode="out-in">
<p :key="message">{{ message }}</p>
</Transition>
<!-- GOOD: Different keys for conditional content -->
<Transition name="fade" mode="out-in">
<div v-if="isLoading" key="loading">Loading...</div>
<div v-else key="content">{{ content }}</div>
</Transition>
</template>
```
## Caution: Performance Implications
Using `:key` forces full component re-creation. For frequently changing data:
- The entire component tree under the keyed element is destroyed and recreated
- Any component state is lost
- Consider whether the animation is worth the performance cost
```vue
<!-- Be cautious with complex components -->
<ComplexDashboard :key="refreshTrigger" />
<!-- This destroys and recreates the entire dashboard! -->
```
