react-animate-on-change

Animate your react components on props or state changes, in contrast to entries added/removed from arrays.

Install

npm install react-animate-on-change react

Usage

import AnimateOnChange from 'react-animate-on-change'
// CommonJS:
// const AnimateOnChange = require('react-animate-on-change').default
 
// functional component
const Score = (props) =>
  <AnimateOnChange
    baseClassName="Score"
    animationClassName="Score--bounce"
    animate={props.diff != 0}>
      Score: {props.score}
  </AnimateOnChange>

The example above will (roughly) render to:

On enter or changes in props.diff or props.score:

<span class="Score Score--bounce">
  <span>Score: 100</span>
</span>

On animation end:

<span class="Score">
  <span>Score: 100</span>
</span>

Also, see the example folder.
