| Provide / Inject | Pass data through component tree without prop drilling |
Provide / Inject
Provide data from ancestor components to any descendant, avoiding prop drilling.
Basic Usage
<!-- Provider.vue -->
<script setup lang="ts">
import { provide, ref } from 'vue'
const message = ref('hello')
provide('message', message)
</script>
<!-- DeepChild.vue (any level deep) -->
<script setup lang="ts">
import { inject } from 'vue'
const message = inject('message')
</script>
Typing with InjectionKey
Use InjectionKey for type safety between provider and injector:
// keys.ts
import type { InjectionKey, Ref } from 'vue'
export const messageKey = Symbol() as InjectionKey<Ref<string>>
export const countKey = Symbol() as InjectionKey<number>
<!-- Provider.vue -->
<script setup lang="ts">
import { provide, ref } from 'vue'
import { messageKey } from './keys'
const message = ref('hello')
provide(messageKey, message)
</script>
<!-- Injector.vue -->
<script setup lang="ts">
import { inject } from 'vue'
import { messageKey } from './keys'
const message = inject(messageKey) // Ref<string> | undefined
</script>
Default Values
// Simple default
const value = inject('message', 'default value')
// Factory function (for expensive defaults)
const value = inject('key', () => new ExpensiveClass(), true)
// ^ treat as factory
App-Level Provide
Available to all components:
// main.ts
import { createApp } from 'vue'
const app = createApp(App)
app.provide('globalConfig', { theme: 'dark' })
Reactive Provide/Inject
Provide reactive values for automatic updates:
<!-- Provider.vue -->
<script setup lang="ts">
import { provide, ref } from 'vue'
const count = ref(0)
provide('count', count)
</script>
The injected value maintains reactivity connection.
Mutations Best Practice
Keep mutations in the provider, expose update functions:
<!-- Provider.vue -->
<script setup lang="ts">
import { provide, ref, readonly } from 'vue'
const location = ref('North Pole')
function updateLocation(newLocation: string) {
location.value = newLocation
}
provide('location', {
location: readonly(location), // Prevent direct mutation
updateLocation
})
</script>
<!-- Injector.vue -->
<script setup lang="ts">
import { inject } from 'vue'
const { location, updateLocation } = inject('location')!
</script>
<template>
<button @click="updateLocation('South Pole')">
{{ location }}
</button>
</template>
Using Symbol Keys
Recommended for libraries and large apps to avoid collisions:
// keys.ts
export const myKey = Symbol('myKey')
// provider
provide(myKey, value)
// injector
inject(myKey)
Type Helpers
// String key with explicit type
const foo = inject<string>('foo')
// ^? string | undefined
// With default (removes undefined)
const foo = inject<string>('foo', 'default')
// ^? string
// Force non-undefined (use when certain it's provided)
const foo = inject('foo') as string
