useLazyAsyncData

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.

useLazyAsyncData has the same signature as useAsyncData.

Example

<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>
