## Description
|
|
|
|
By default, [`useFetch`](/docs/api/composables/use-fetch) blocks navigation until its async handler is resolved. `useLazyFetch` provides a wrapper around [`useFetch`](/docs/api/composables/use-fetch) that triggers navigation before the handler is resolved by setting the `lazy` option to `true`.
|
|
|
|
::note
|
|
`useLazyFetch` has the same signature as [`useFetch`](/docs/api/composables/use-fetch).

|
## Example
|
|
|
|
```vue [pages/index.vue]
|
|
<script setup lang="ts">
|
|
/* Navigation will occur before fetching is complete.
|
|
* Handle 'pending' and 'error' states directly within your component's template
|
|
*/
|
|
const { status, data: posts } = await useLazyFetch('/api/posts')
|
|
watch(posts, (newPosts) => {
|
|
// Because posts might start out null, you won't have access
|
|
// to its contents immediately, but you can watch it.
|
|
})
|
|
</script>
|
|
|
|
<template>
|
|
<div v-if="status === 'pending'">
|
|
Loading ...
|
|
</div>
|
|
<div v-else>
|
|
<div v-for="post in posts">
|
|
<!-- do something -->
|
|
</div>
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
::note
|
|
`useLazyFetch` is a reserved function name transformed by the compiler, so you should not name your own function `useLazyFetch`.
