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

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

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

Container, Bar and Spinner are custom components. NProgress is the only component exposed by this package. It doesn't render anything itself, it just calls the render function and renders that:

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

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