读作 安努 ,苏美尔的主神,开天辟地。一个无痛替换线上React的迷你React框架 QQ交流学习群: 370262116

特点:

  1. 支持React的无狀态组件,纯组件,高阶组件,受控组件与非受控组件
  2. 命名空间就是React,此外还暴露了另一个别名ReactDOM在window上
  3. 体积足够少(1700行相对于react+react-dom的3万行)
  4. 性能是官方React的两倍以上 测试页面结果统计
  5. 生命周期函数的参数与官方保持一致
  6. 直接与react-redux, react-router-dom, react-router-redux混用
  7. 支持后端渲染
  8. 支持官方的chrome DevTools

dist目录下的变种说明

  1. React 支持IE9+, 拥有PropTypes, createClass, createFactory
  2. ReactIE 支持IE6+, 拥有PropTypes, createClass, createFactory (需要与lib目录下的polyfill配套使用)
  3. ReactShim 要求浏览器支持es6 Map对象,并且与react1.6靠近,删除了PropTypes, createClass, createFactory

开源协议

Apache Licene 2.0

低版本浏览器可能需要以下 语言补丁

  1. Array.isArray
  2. Object.assign
  3. JSON.stringify
  4. console-polyfill
  5. Object.is
  6. Object.keys
  7. Array.prototype.forEach
  8. Function.prototype.bind

或者直接使用polyfill.js https://github.com/RubyLouvre/anu/blob/master/lib/polyfill.js

如果想用anujs代替已经用React.js写好或正在进行的的项目,可以这样配置webpack

// webpack.config.js
    resolve: {
        alias: {
            'react': 'anujs',
            'react-dom': 'anujs',
            'prop-types': 'anujs/lib/ReactPropTypes',
            'create-react-class': 'anujs/lib/createClass'
 
        }
    }
