【心有猛虎】react-lesson
这个项目标识：构建一套适合 React、ES6 开发的脚手架
项目地址为：https://github.com/ZengTianShengZ/react-lesson
运行的是第一课，基本上可以当作是一个小型的项目，毕竟路由还有组件目录挺全的，不过，没有深入，记一下

项目中的第二个例子就是老生常谈了
太冗杂了，我都不愿意去看，一般都会抽分reducer,action，store
//lesson-2/src/App.jsx
import React,{Component,PropTypes} from 'react';
import ReactDOM, {render} from 'react-dom';
import {Provider,connect} from 'react-redux';
import {createStore, combineReducers, applyMiddleware} from 'redux';
import Index from './Component/Main.jsx';
import './Style/comm.scss'
// reducer
const reducer = (state = {count: 0}, action) => {
switch (action.type){
case 'INCREASE': return {count: state.count + 1};
case 'DECREASE': return {count: state.count - 1};
default: return state;
}
}
const store = createStore(reducer);
//监听state变化
store.subscribe(() => {
//console.log(store.getState())
});
render(
<Provider store={store}>
<Index></Index>
</Provider>,
document.body.appendChild(document.createElement('div'))
);
//lesson-2/src/Component/Main.jsx
import React, {Component, PropTypes} from 'react';

}
}
render(){
// 拿到 this.props 参数
const {count, increase, decrease} = this.props;
return(
<div>
<p className="lesson-2">React lesson-2</p>
<p>
---------------------------------
</p>
<div className="count">

)
}
}
/**

const mapStateToProps = (state) => {
return {

}
};
/**

*/
const mapDispatchToProps = (dispatch, ownProps) => {
return {

};

哎，第三节也是简单的项目
不过 服务是nodejs起的
