Docs Guide Directory Structure
composables
Use the composables/ directory to auto-import your Vue composables into your application.
Usage
Method 1: Using named export
export const useFoo = () => { return useState('foo', () => 'bar')}
Method 2: Using default export
// It will be available as useFoo() (camelCase of file name without extension)export default function () { return useState('foo', () => 'bar')}
Usage: You can now use auto imported composable in .js
, .ts
and .vue
files
<script setup lang="ts">const foo = useFoo()</script><template> <div> {{ foo }} </div></template>
Types
Under the hood, Nuxt auto generates the file .nuxt/imports.d.ts
to declare the types.
Be aware that you have to run nuxi prepare
, nuxi dev
or nuxi build
in order to let Nuxt generate the types.
Cannot find name 'useBar'.
Examples
Nested Composables
You can use a composable within another composable using auto imports:
export const useFoo = () => { const nuxtApp = useNuxtApp() const bar = useBar()}
Access plugin injections
You can access plugin injections from composables:
export const useHello = () => { const nuxtApp = useNuxtApp() return nuxtApp.$hello}
How Files Are Scanned
Nuxt only scans files at the top level of the composables/
directory, e.g.:
| composables/---| index.ts // scanned---| useFoo.ts // scanned-----| nested/-------| utils.ts // not scanned
Only composables/index.ts
and composables/useFoo.ts
would be searched for imports.
To get auto imports working for nested modules, you could either re-export them (recommended) or configure the scanner to include nested directories:
Example: Re-export the composables you need from the composables/index.ts
file:
// Enables auto import for this exportexport { utils } from './nested/utils.ts'
Example: Scan nested directories inside the composables/
folder:
export default defineNuxtConfig({ imports: { dirs: [ // Scan top-level modules 'composables', // ... or scan modules nested one level deep with a specific name and file extension 'composables/*/index.{ts,js,mjs,mts}', // ... or scan all modules within given directory 'composables/**' ] }})
