Nuxt (>= 2.12) Fetch

June 12, 2020

vuejs
nuxtjs

The easiest way to fetch data using Nuxt is via asyncData, as a lot of things is handled for you (loading animation, data merging, state management, etc) and it just works.

If you need more control, you should use fetch.

Render UI based on $fetchState (loading, error and success)
Have access to this / page component.
Ability to disable fetchOnServer forcing fetch to be called on client side only
Ability to call this.$fetch()
Enable fetch cache

Code

<template>
  <div>
    <div v-if="$fetchState.pending">Loading ...</div>
    <div v-else-if="$fetchState.error">Error: {{ $fetchState.error.message }}</div>
    <div>
      {{ title }}
    </div>
  </div>
</template>

<script>
export default {
  async fetch() {
    // const HOST = 'http://localhost:8080' // required for server-side fetch
    // const url = new URL(`/data/test.json`, HOST)
    const url = 'https://jsonplaceholder.typicode.com/posts/1'
    // alternatvely, you could use $axios or $http
    const res = await fetch(url)
    const data = await res.json()

    this.title = data.title
  },
  data() {
    return {
      title: null
    }
  },
}
</script>
