## Introduction
react-lite is an implementation of React that optimizes for small script size.
### Framework Size Comparison

| Ember                  | 2.2.0      | 446.0kb       |
| Polymer                | 1.0.6      | 183.0kb       |

React-lite supports the core APIs of React, such as Virtual DOM, intended as a drop-in
replacement for React, when you don't need server-side rendering in browser(no `ReactDOM.renderToString` & `ReactDOM.renderToStaticMarkup`).

If you are using webpack, it's so easy to use react-lite, just [config alias](http://webpack.github.io/docs/configuration.html#resolve-alias) in webpack.config.js:

```javascript
// webpack.config.js
{
    resolve: {
        alias: {
            'react': 'react-lite',
            'react-dom': 'react-lite'
        }
    }
}
```

Note: feel free to try react-lite, if something happen and we can't fix it in time, then use [regular react](https://github.com/facebook/react) instead.
## Installation

You can install react-lite from npm:

```shell
npm install react-lite --save
```

## Browser compatibility

supports IE9+ / ES5 enviroment

## Documentation

learn react-lite from [React official documentation](http://facebook.github.io/react/)

## What can react-lite do?

just the same as what react does, see some demos below(I just add the alias to webpack.config.js, no need to do anything else):

- works with react-bootstrap: [doc demo](http://react-lite-with-bootstrap.herokuapp.com/)
- works with ant-design: [demo](http://lucifier129.github.io/ant-design/)
- works with react-router: [examples](http://react-lite-with-react-router.coding.io/)
- works with redux:
	* [async](http://lucifier129.github.io/redux-with-react-lite/async/index.html)
	* [counter](http://lucifier129.github.io/redux-with-react-lite/counter/index.html)
	* [shopping-cart](http://lucifier129.github.io/redux-with-react-lite/shopping-cart/index.html)
	* [todomvc](http://lucifier129.github.io/redux-with-react-lite/todomvc/index.html)
	* [todos-with-undo](http://lucifier129.github.io/redux-with-react-lite/todos-with-undo/index.html)
- works with react-motion: [demos](http://lucifier129.github.io/react-motion-with-react-lite/index.html)

- react-lite [vdom-benchmark](http://vdom-benchmark.github.io/vdom-benchmark/)
- js-repaint-perf:
	* [react](http://lucifier129.github.io/react-lite-repaint-perf/react/index.html)
	* [react-lite](http://lucifier129.github.io/react-lite-repaint-perf/react/lite.html)

## React-lite vs React

via react-lite:
- all of React.PropTypes method is no-op(empty function)
- use React in server side rendering, and use React-lite in browser
	* react-lite will replace the dom tree with new dom tree
	* you had better avoid `script|head|link` tag in client side
- can not use react-dev-tool inspect react-lite, should switch to regular react for debugging
- react-lite only works with a JSX toolchain([issue](https://github.com/Lucifier129/react-lite/issues/51))
- unlike react, `event` object in react-lite is always persistent, and `event.persist` is set as no-op to avoid throwing error.
- react-lite can't work with `react-tap-event-plugin`, please use `fastclick` instead.

## Test
react-lite reuses react's unitest(170), you can see them in `__test__`, and run the tests with:

```shell
npm test
```
