This wrapper around useFetch triggers navigation immediately.

useLazyFetch

useLazyFetch provides a wrapper around useFetch that triggers navigation before the handler is resolved by setting the lazy option to true.

Description

By default, useFetch blocks navigation until its async handler is resolved.

useLazyFetch has the same signature as useFetch.

Example

<template>
  <div v-if="pending">
    Loading ...
  </div>
  <div v-else>
    <div v-for="post in posts">
      <!-- do something -->
    </div>
  </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: posts } = useLazyFetch('/api/posts')
watch(posts, (newPosts) => {
  // Because posts starts out null, you won't have access
  // to its contents immediately, but you can watch it.
})
</script>
