useNProgress

Reactive wrapper for nprogress.

Demo

Usage

import { useNProgress } from '@vueuse/integrations/useNProgress'

const { isLoading } = useNProgress()

function toggle() {
  isLoading.value = !isLoading.value
}

import { useNProgress } from '@vueuse/integrations/useNProgress'

const { isLoading } = useNProgress()

function toggle() {
  isLoading.value = !isLoading.value
}

Passing a progress percentage

You can pass a percentage to indicate where the bar should start from.

import { useNProgress } from '@vueuse/integrations/useNProgress'

const { progress } = useNProgress(0.5)

function done() {
  progress.value = 1.0
}

import { useNProgress } from '@vueuse/integrations/useNProgress'

const { progress } = useNProgress(0.5)

function done() {
  progress.value = 1.0
}

To change the progress percentage, set progress.value = n, where n is a number between 0..1.

Customization

Just edit nprogress.css to your liking. Tip: you probably only want to find and replace occurrences of #29d.

You can configure it by passing an object as a second parameter.

import { useNProgress } from '@vueuse/integrations/useNProgress'

useNProgress(null, {
  minimum: 0.1,
  // ...
})

import { useNProgress } from '@vueuse/integrations/useNProgress'

useNProgress(null, {
  minimum: 0.1,
  // ...
})
