Documentation

Nuxt.js uses it's own component to show a progress bar between the routes. You can customize it, disable it or create your own component.

Disable Nuxt.js progress bar

If you don't want to display the progress bar between the routes, just add loading: false in your nuxt.config.js file:

// nuxt.config.js
module.exports = {
  loading: false
}

Customize Nuxt.js progress bar

Here are the properties you can customize for Nuxt.js progress bar.

Key Type Default Description
color String 'black' CSS color of the progress bar
failedColor String 'red' CSS color of the progress bar when an error appended during rendering the route (if data or fetch sent back an error for example).
height String '2px' Height of the progress bar (used in the style property of the progress bar)
duration Number 5000 In ms, the maximum duration of the progress bar, Nuxt.js assumes that the route will be rendered before 5 seconds.

Example:

// nuxt.config.js
module.exports = {
  loading: {
    color: 'blue',
    height: '5px'
  }
}

Create a custom loading component

You can create your own component that Nuxt.js will call instead of its default component. To do so, you need to give a path to your component in the loading option.

Your custom component will be called by Nuxt.js, so make sure your component exposes some of theses methods:

| Method | Required | Description | |--------|-------------| | start() | Required | Called when a route changes, this is here where you should show your component. | | finish() | Required | Called when a route is loaded (and data fetched), this is here where you should hide your component. | | fail() | Optional | Called when a route could not be loaded (failed to fetch data for example). | | increase(num) | Optional | Called during loading the route component, num is an Integer < 100. |

Example:

// nuxt.config.js
module.exports = {
  loading: 'components/loading.vue'
}

And then, in components/loading.vue:

<template lang="html">
  <div class="loading-page" v-if="loading">
    <p>Loading...</p>
  </div>
</template>

<script>
export default {
  data: () => ({
    loading: false
  }),
  methods: {
    start () {
      this.loading = true
    },
    finish () {
      this.loading = false
    }
  }
}
</script>

<style scoped>
.loading-page {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(255, 255, 255, 0.8);
  text-align: center;
  padding-top: 200px;
  font-size: 30px;
  font-family: sans-serif;
}
</style>
