react-nprogress

A React primitive for building slim progress bars.

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

Render Props

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

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

Container, Bar and Spinner are custom components. NProgress doesn't render anything itself, it just calls the render function and renders that:

<NProgress>
  {({/* parameters here */}) => (/* your render code here */)}
</NProgress>

HOC

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

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.

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}
/>
