react-css-transition-light

react-css-transition is an easy way to perform CSS transitions and animations when a React Componenet enters or leaves the DOM.

Demo & Examples

Live demo: BellaChoi.github.io/react-css-transition-light

To build the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.

Installation

The easiest way to use react-css-transition-light is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).

You can also use the standalone build by including dist/react-css-transition-light.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-css-transition-light --save

Usage

var ReactCssTransition = require('react-css-transition-light');

<ReactCssTransition className='example-box'
  visible={this.state.isShow}
  enterTimeout={1000}
  leaveTimeout={1000}
  onEnterTransitionStart={this.onEnterTransitionStart.bind(this)}
  onEnterTransitionEnd={this.onEnterTransitionEnd.bind(this)}
  onLeaveTransitionStart={this.onLeaveTransitionStart.bind(this)}
  onLeaveTransitionEnd={this.onLeaveTransitionEnd.bind(this)}
  options={{ onClick: this.togglePopup.bind(this) }} > Click! </ReactCssTransition>

Properties

Property	Type	Description	Default
visible	bool	Initialize state	True
className	string	custom class name
enterTimeout	number	the number of milliseconds	500
leaveTimeout	number	the number of milliseconds	500
options	object	other props
onEnterTransitionStart	function	called at the start of 'enter transition'
onEnterTransitionEnd	function	called at the end of 'enter transition'
onLeaveTransitionStart	function	called at the start of 'leave transition'
onLeaveTransitionEnd	function	called at the end of 'leave transition'

Notes

In css, className according to transition state is defined as follows. when className is 'example',

.example-box {
  ...
  -webkit-transition: opacity 1000ms ease;
  -moz-transition: opacity 1000ms ease;
  -ms-transition: opacity 1000ms ease;
  -o-transition: opacity 1000ms ease;
  transition: opacity 1000ms ease;
}

.example-box.enter {
  opacity: 1;
}
.example-box.leave {
  opacity: 0;
}

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).
