# Composables directory

Nuxt 3 supports `composables/` directory to auto import your Vue composables into your application and use using auto imports!


Example: (using named exports)

```js [composables/useFoo.ts]
import { useState } from '#app'

export const useFoo = () => {
  return useState('foo', () => 'bar')
}
```

Example: (using default export)

```js [composables/use-foo.ts or composables/useFoo.ts]
import { useState } from '#app'

// It will be available as useFoo() (pascalCase of file name without extension)
export default function () {
  return 'bar'
}
```

You can now auto import it:

```vue [app.vue]
<template>
  <div>
    {{ foo }}
  </div>
</template>

<script setup>
const foo = useFoo()
</script>
```
