# useObjectUrl
|
|
|
|
Reactive URL representing an object.
|
|
|
|
Creates an URL for the provided `File`, `Blob`, or `MediaSource` via [URL.createObjectURL()](https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL) and automatically releases the URL via [URL.revokeObjectURL()](https://developer.mozilla.org/en-US/docs/Web/API/URL/revokeObjectURL) when the source changes or the component is unmounted.
|
|
|
|
## Usage
|
|
|
|
```vue
|
|
<script setup lang="ts">
|
|
import { useObjectUrl } from '@vueuse/core'
|
|
import { shallowRef } from 'vue'
|
|
|
|
const file = shallowRef()
|
|
const url = useObjectUrl(file)
|
|
|
|
function onFileChange(event) {
|
|
file.value = event.target.files[0]
|
|
}
|
|
</script>
|
|
|
|
<template>
|
|
<input type="file" @change="onFileChange">
|
|
|
|
<a :href="url">Open file</a>
|
|
</template>
|
|
```
|
|
|
|
## Component Usage
|
|
|
|
```vue
|
|
<template>
|
|
<UseObjectUrl v-slot="url" :object="file">
|
|
<a :href="url">Open file</a>
|
|
</UseObjectUrl>
|
|
</template>
|
|
```
|
|
|
|

|
|
|

|
|
/**
|
|
* Reactive URL representing an object.
