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.
