The loading property

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

  • Type: Boolean or Object or String 
export default {
  mounted() {
    this.$nextTick(() => {
      this.$nuxt.$loading.start()

      setTimeout(() => this.$nuxt.$loading.finish(), 500)
    })
  }
}

Disable the Progress Bar

  • Type: Boolean
nuxt.config.js
export default {
  loading: false
}

Customizing the Progress Bar

  • Type: Object 
export default {
  loading: {
    color: 'blue',
    height: '5px'
  }
}

List of properties to customize the 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 while 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)
throttle Number 200 In ms, wait for the specified time before displaying the progress bar. Useful for preventing the bar from flashing.
duration Number 5000 In ms, the maximum duration of the progress bar, Nuxt assumes that the route will be rendered before 5 seconds.
continuous Boolean false Keep animating progress bar when loading takes longer than duration.
css Boolean true Set to false to remove default progress bar styles (and add your own).
rtl Boolean false Set the direction of the progress bar from right to left.

Using a Custom Loading Component

  • Type: String

Your component has to expose some of these methods:

Method Required Description
start() Required Called when a route changes, this is where you display your component.
finish() Required Called when a route is loaded (and data fetched), this is where you hide your component.
fail(error) Optional Called when a route couldn't be loaded (failed to fetch data for example).
increase(num) Optional Called during loading the route component, num is an Integer < 100.
