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 } = 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>
useLazyAsyncData
is a reserved function name transformed by the compiler, so you should not name your own function useLazyAsyncData
.
