# Auto imports
|
|
|
|
Nuxt auto-imports helper functions, composables and Vue APIs to use across your application without explicitly importing them. Based on the directory structure, every Nuxt application can also use auto-imports for its own components, composables and plugins. Components, composables or plugins can use these functions.
|
|
|
|
Contrary to a classic global declaration, Nuxt preserves typings and IDEs completions and hints, and only includes what is actually used in your production code.

|
|
In the documentation, every function that is not explicitly imported is auto-imported by Nuxt and can be used as-is in your code.
|
|
You can find a reference for auto-imported [composables](/api/composables/use-async-data) and [utilities](/api/utils/dollarfetch) in the API section.

Auto imports don't currently work within the [server directory](/guide/directory-structure/server).

## Nuxt Auto-imports
|
|
|
|
Nuxt auto-imports functions and composables to perform [data fetching](/getting-started/data-fetching), get access to the [app context](/api/composables/use-nuxt-app) and [runtime config](/guide/going-further/runtime-config), manage [state](/getting-started/state-management) or define components and plugins.
|
|
|
|
```vue
|
|
<script setup>
|
|
/* useAsyncData() and $fetch() are auto-imported */
|
|
const { data, refresh, pending } = await useAsyncData('/api/hello', () => $fetch('/api/hello'))
|
|
</script>
|
|
```
|
|
|
|
## Vue Auto-imports
|
|
|
|
Vue 3 exposes Reactivity APIs like `ref` or `computed`, as well as lifecycle hooks and helpers that are auto-imported by Nuxt.
|
|
|
|
```vue
|
|
<script setup>
|
|
/* ref() and computed() are auto-imported */
|
|
const count = ref(1)
|
|
const double = computed(() => count.value * 2)
|
|
</script>
|
|
```
|
|
|
|
## Directory-based Auto-imports
|
|
|
|
Nuxt directly auto-imports files created in defined directories:
|
|
|
|
- `components/` for [Vue components](/guide/directory-structure/components).
|
|
- `composables/` for [Vue composables](/guide/directory-structure/composables).
|
|
|
|
## Explicit Imports
|
|
|
|
Nuxt exposes every auto-import with the `#imports` alias that can be used to make the import explicit if needed:
|
|
|
|
```vue
|
|
<script setup>
|
|
import { ref, computed } from '#imports'
|
|
|
|
const count = ref(1)
|
|
const double = computed(() => count.value * 2)
|
|
</script>
|
|
```
|
|
|
|
## Disable Auto-imports
|
|
|
|
In case you want to disable auto-imports, you can set `imports.autoImport` to `false`.
|
|
|
|
```ts [nuxt.config.ts]
|
|
export default defineNuxtConfig({
|
|
imports: {
|
|
autoImport: false
|
|
}
|
|
})
|
|
```
|
|
|
|
This will disable implicit auto imports completely but it's still possible to use [Explicit Imports](#explicit-imports).
