useLazyAsyncData	This wrapper around useAsyncData triggers navigation immediately.	label icon to size Source i-simple-icons-github https://github.com/nuxt/nuxt/blob/main/packages/nuxt/src/app/composables/asyncData.ts xs

Description

By default, useAsyncData blocks navigation until its async handler is resolved. useLazyAsyncData provides a wrapper around useAsyncData that triggers navigation before the handler is resolved by setting the lazy option to true.

::callout useLazyAsyncData has the same signature as useAsyncData. ::

Example

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

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

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

::callout{color="amber" icon="i-ph-warning-duotone"} useLazyAsyncData is a reserved function name transformed by the compiler, so you should not name your own function useLazyAsyncData. ::
