Background

This is a React port of rstacruz's nprogress module. It exposes an API that encapsulates the logic of nprogress and renders nothing, giving you complete control over rendering.

Usage

In the following examples, Container, Bar and Spinner are custom components. NProgress doesn't render anything itself.

Hook

import { useNProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

const Progress = ({ isAnimating }) => {
  const { animationDuration, isFinished, progress } = useNProgress({
    isAnimating
  })

  return (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )
}

render(<Progress isAnimating />, document.getElementById('root'))

Render Props

import { NProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

render(
  <NProgress isAnimating>
    {({ animationDuration, isFinished, progress }) => (
      <Container animationDuration={animationDuration} isFinished={isFinished}>
        <Bar animationDuration={animationDuration} progress={progress} />
        <Spinner />
      </Container>
    )}
  </NProgress>,
  document.getElementById('root')
)

HOC

import { withNProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

const Inner = ({ animationDuration, isFinished, progress }) => (
  <Container animationDuration={animationDuration} isFinished={isFinished}>
    <Bar animationDuration={animationDuration} progress={progress} />
    <Spinner />
  </Container>
)

const Enhanced = withNProgress(Inner)

render(<Enhanced isAnimating />, document.getElementById('root'))

API

Props

• animationDuration - Optional Number indicating the animation duration in ms. Defaults to 200.
• incrementDuration - Optional Number indicating the length of time between progress bar increments in ms. Defaults to 800.
• isAnimating - Optional Boolean indicating if the progress bar is animating. Defaults to false.
• minimum - Optional Number between 0 and 1 indicating the minimum value of the progress bar. Defaults to 0.08.

Hook Example

const Progress = ({
  animationDuration,
  incrementDuration,
  isAnimating,
  minimum
}) => {
  const { isFinished, progress } = useNProgress({
    animationDuration,
    incrementDuration,
    isAnimating,
    minimum
  })

  return (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )
}

<Progress
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
/>

Render Props Example

<NProgress
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
>
  {({ animationDuration, isFinished, progress }) => (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )}
</NProgress>

HOC Example

const Inner = ({ animationDuration, isFinished, progress }) => (
  <Container animationDuration={animationDuration} isFinished={isFinished}>
    <Bar animationDuration={animationDuration} progress={progress} />
    <Spinner />
  </Container>
)

const Enhanced = withNProgress(Inner)

<Enhanced
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
/>
