Use suspensible Prop for Nested Suspense (Vue 3.3+)

Rule

When nesting <Suspense> components, use the suspensible prop on the inner Suspense to properly coordinate with the parent Suspense. Without this prop, nested async components may render empty nodes until resolved instead of showing fallback content.

Why This Matters

Without the suspensible prop, the inner <Suspense> is treated as a synchronous component by the parent. This causes:

Empty nodes appearing briefly during async resolution
Multiple patching cycles as the component tree updates
Inconsistent loading states that confuse users

Bad Code

<template>
  <Suspense>
    <component :is="DynamicAsyncOuter">
      <!-- DynamicAsyncInner renders EMPTY until resolved! -->
      <component :is="DynamicAsyncInner" />
    </component>

    <template #fallback>
      Loading...
    </template>
  </Suspense>
</template>

<template>
  <Suspense>
    <OuterLayout>
      <!-- Inner Suspense not coordinated with parent -->
      <Suspense>
        <AsyncWidget />
        <template #fallback>Loading widget...</template>
      </Suspense>
    </OuterLayout>

    <template #fallback>
      Loading layout...
    </template>
  </Suspense>
</template>

Good Code

<template>
  <Suspense>
    <component :is="DynamicAsyncOuter">
      <!-- Inner Suspense with suspensible prop -->
      <Suspense suspensible>
        <component :is="DynamicAsyncInner" />
        <template #fallback>
          <InnerLoadingState />
        </template>
      </Suspense>
    </component>

    <template #fallback>
      <OuterLoadingState />
    </template>
  </Suspense>
</template>

Complex Layout Example

<template>
  <Suspense>
    <DashboardLayout>
      <template #sidebar>
        <!-- Sidebar has its own Suspense boundary -->
        <Suspense suspensible>
          <AsyncSidebar />
          <template #fallback>
            <SidebarSkeleton />
          </template>
        </Suspense>
      </template>

      <template #main>
        <!-- Main content has its own Suspense boundary -->
        <Suspense suspensible>
          <AsyncMainContent :key="contentKey" />
          <template #fallback>
            <ContentSkeleton />
          </template>
        </Suspense>
      </template>

      <template #widgets>
        <!-- Each widget can load independently -->
        <Suspense suspensible>
          <AsyncWidgets />
          <template #fallback>
            <WidgetsSkeleton />
          </template>
        </Suspense>
      </template>
    </DashboardLayout>

    <template #fallback>
      <FullPageLoader />
    </template>
  </Suspense>
</template>

How suspensible Works

Configuration	Behavior
No `suspensible` prop	Inner Suspense treated as sync; parent doesn't wait for inner async deps
`suspensible` on inner	Inner async deps bubble up to parent Suspense for coordinated loading

When to Use Nested Suspense

Use nested Suspense with suspensible when:

Different page sections should show their own loading states
You want granular control over which parts show loading indicators
Sections can load at different speeds and should update independently

Avoid nested Suspense when:

A single loading state for the whole component is sufficient
The complexity isn't worth the UX benefit
You're targeting Vue versions before 3.3

Key Points

Always add suspensible prop when nesting Suspense components
Without suspensible, expect empty nodes and multiple patching cycles
This feature requires Vue 3.3 or later
Use nested Suspense boundaries strategically for better UX, not everywhere
Each Suspense can have its own fallback for section-specific loading states
