computedWithControl
Explicitly define the dependencies of computed.
Usage
import { computedWithControl } from '@vueuse/core'
const source = ref('foo')
const counter = ref(0)
const computedRef = computedWithControl(
() => source.value, // watch source, same as `watch`
() => counter.value, // computed getter, same as `computed`
)
With this, the changes of counter won't trigger computedRef to update but the source ref does.
// @include: main
// ---cut---
console.log(computedRef.value) // 0
counter.value += 1
console.log(computedRef.value) // 0
source.value = 'bar'
console.log(computedRef.value) // 1
Manual Triggering
You can also manually trigger the update of the computed by:
// @include: main
// ---cut---
const computedRef = computedWithControl(
() => source.value,
() => counter.value,
)
computedRef.trigger()
Deep Watch
Unlike computed, computedWithControl is shallow by default.
You can specify the same options as watch to control the behavior:
const source = ref({ name: 'foo' })
const computedRef = computedWithControl(
source,
() => counter.value,
{ deep: true },
)
