The main purpose of the [`utils/` directory](/docs/guide/directory-structure/utils) is to allow a semantic distinction between your Vue composables and other auto-imported utility functions.

## Usage

**Method 1:** Using named export

```ts twoslash [utils/index.ts]
export const { format: formatNumber } = Intl.NumberFormat('en-GB', {
  notation: 'compact',
  maximumFractionDigits: 1
})
```

**Method 2:** Using default export

```ts twoslash [utils/random-entry.ts or utils/randomEntry.ts]
// It will be available as randomEntry() (camelCase of file name without extension)
export default function (arr: Array<any>) {
  return arr[Math.floor(Math.random() * arr.length)]
}
```

You can now use auto imported utility functions in `.js`, `.ts` and `.vue` files

```vue [app.vue]
<template>
  <p>{{ formatNumber(1234) }}</p>
</template>
```

::tip
The way `utils/` auto-imports work and are scanned is identical to the [`composables/`](/docs/guide/directory-structure/composables) directory.
::

::important
These utils are only available within the Vue part of your app. :br
Only `server/utils` are auto-imported in the [`server/`](/docs/guide/directory-structure/server#server-utilities) directory.
