sequential fade-out, fade-in component, with optional height/width animation. Works with react-router

react-fader

A React Component that fades out its old child, then fades in its new child when its children change. It can also optionally animate its height and/or width from one child's size to the other. Works well with react-router!

Usage

npm install --save react-fader

import React from 'react'
import ReactDOM from 'react-dom'
import Fader from 'react-fader'

ReactDOM.render(
  <Fader>
    <h3>Foo</h3>
  </Fader>,
  document.getElementById('root')
)

// Just change its children to something !==, and it will perform a fade transition.

ReactDOM.render(
  <Fader>
    <h3>Bar</h3>
  </Fader>,
  document.getElementById('root')
)

Transitioning between child routes with react-router version 4

While it can be done with <Switch>, I recommend using react-router-transition-switch instead:

import {Route, BrowserRouter as Router} from 'react-router-dom'
import TransitionSwitch from 'react-router-transition-switch'
import Fader from 'react-fader'

<Router>
  <TransitionSwitch component={Fader}>
    <Route path="/red" component={Red}/>
    <Route path="/green" component={Green} />
    <Route path="/blue" component={Blue} />
  </TransitionSwitch>
<Router>

Props

If truthy, Fader will animate its height to match the height of its children.

animateWidth: boolean (default: true)

If truthy, Fader will animate its width to match the height of its children.

shouldTransition: (oldChildren: any, newChildren: any) => boolean (default: compares keys)
