# `useLazyAsyncData`

`useLazyAsyncData` provides a wrapper around `useAsyncData` that triggers navigation before the handler is resolved by setting the `lazy` option to `true`.

## Description

By default, [useAsyncData](/docs/api/composables/use-async-data) blocks navigation until its async handler is resolved.

> `useLazyAsyncData` has the same signature as `useAsyncData`.

## Example

```vue
<template>
  <div>
    {{ pending ? 'Loading' : count }}
  </div>
</template>

<script setup>
/* Navigation will occur before fetching is complete.
  Handle pending and error states directly within your component's template
*/
const { pending, data: count } = useLazyAsyncData('count', () => $fetch('/api/count'))

watch(count, (newCount) => {
  // Because count starts out null, you won't have access
  // to its contents immediately, but you can watch it.
})
</script>
```

::alert{type=warning}
`useLazyAsyncData` is a reserved function name transformed by the compiler, so you should not name your own function `useLazyAsyncData`.
