(Module exposed as `ReactMotionLoop`)

Usage

import React from 'react';
import ReactDOM from 'react-dom';
import {spring} from 'react-motion';
import {ReactMotionLoop} from 'react-motion-loop';


const App = () => (
  <div>
    <h1>Looping animation</h1>
    <ReactMotionLoop
      styleFrom={{width: spring(0), height: spring(0)}}
      styleTo={{width: spring(100), height: spring(100)}}>
      {style => <div style={style} />}
    </ReactMotionLoop>

    <h1>Pulsing animation</h1>
    <ReactMotionLoop
      styleFrom={{width: 0, height: 0}} // Instantly jump to the initial style
      styleTo={{width: spring(100), height: spring(100)}}>
      {style => <div style={style} />}
    </ReactMotionLoop>
  </div>
);

const appRoot = document.createElement('div');
document.body.appendChild(appRoot);
ReactDOM.render(<App />, appRoot);

Options

styleFrom: PropTypes.object.isRequired

Initial style for animated element, used for ReactMotion's defaultStyle and as returning animation

styleTo: PropTypes.object.isRequired

Element is animated to this style, used for ReactMotion's style

All arbitrary props will be transferred to <Motion> as is

WARN: passing onRest, style or defaultStyle will override looping behavior, since internally Motion is used like:

<Motion
  defaultStyle={defaultStyle}
  onRest={this.onRest}
  style={style}
  {...props} />

Development and testing

Currently is being developed and tested with the latest stable Node on OSX.

git clone [email protected]:nkbt/react-motion-loop.git
cd react-motion-loop
yarn install
yarn start

# then
open http://localhost:8080

Tests
