react-web-animation

react-web-animation is a set of React components that expose the Web Animations API in a declarative way.

Demos

Why?

Why use this over other animation libraries for React? react-web-animation uses the Web Animations API polyfill so eventually it will use the native browser implementation and not depend on any third-party animation frameworks or CSS. Chrome has the greatest support for these today and if you view the source on the demos, you can see it isn't using CSS at all!

Features

• Animate Single Elements with a <Animated.[componentName]> e.g. <Animated.div> and control play state (play, pause, stop, reverse)
• Animate Single Elements with a <Animation> and control play state (play, pause, stop, reverse)
• Animate Multiple animations in parallel with a <AnimationGroup>, controlling them with one timeline
• Animate Multiple animations serially with a <AnimationSequence>, controlling them with one timeline

Usage

Creating an animated element is as simple using an <Animated.[elementName]> component and supplying keyframes and a timing config.

import React, { Component } from 'react';
import { Animated } from 'react-web-animation';


export default class Basic extends Component {

    getKeyFrames() {
        return [
            { transform: 'scale(1)',    opacity: 1,     offset: 0 },
            { transform: 'scale(.5)',   opacity: 0.5,   offset: 0.3 },
            { transform: 'scale(.667)', opacity: 0.667, offset: 0.7875 },
            { transform: 'scale(.6)',   opacity: 0.6,   offset: 1 }
        ];
    }

    getTiming( duration ) {
        return {
            duration,
            easing: 'ease-in-out',
            delay: 0,
            iterations: 2,
            direction: 'alternate',
            fill: 'forwards'
        };
    }

    render() {
        return
            <Animated.div keyframes={this.getKeyFrames()}
                       timing={this.getTiming(2500)}>
                    Web Animations API Rocks
            </Animated.div>;
    }
}
