const App = () => (

)

render(<App />, document.getElementById('root'))
    // src/index.less

    color: #008000;
}
    <!-- src/index.html -->
<!DOCTYPE html>

    <title>STAGE</title>
</head>

<body>
    <div id="root"></div>
</body>

</html>

    修改package.json，添加执行脚本

    "scripts": {
    "test": "echo "Error: no test specified" && exit 1",
    "start": "webpack-dev-server --config ./build/webpack.config.js --open",
    "build": "webpack --config ./build/webpack.config.js"
  },

    此时执行npm run build可以看到build目录下生成了dist文件夹 ，npm start可以启动3001端口访问到写的index.js中的内容（如果有报错请检查依赖是否安装成功）

    接入react-router

    npm install -D react-router-dom // 安装react-router-dom依赖

    修改src/index.js文件，此处使用的是HashRouter，如果使用BrowserRouter需要服务端做相应的响应，原理可以对比hash路由和history的区别（可以分别使用两种Router，切换路由时看具体网络请求就明白了）

    // src/index.js
import React from 'react'
import { render } from 'react-dom'
import {
    HashRouter,
    Route,
    Switch,
    Redirect,
} from 'react-router-dom'
import styles from './index.less'

const Home = () => (
    　　    <div>HOME HOHOHO</div>
    )
const Page1 = () => (
　　<div>PAGE1 HOHOHO</div>
    )
const Page2 = () => (　　
　　<div>PAGE2 HOHOHO</div>
    )

const App = () => (
    <>
        <div className={styles.hohoho}>STAGE HOHOHO</div>
        <li><a href='#/home'>去home</a></li>
        <li><a href='#/page1'>去page1</a></li>
        <li><a href='#/page2'>去page2</a></li>
        <hr />
        <HashRouter>
            <Switch>
                <Route exact path='/home' component={Home} />
                <Route exact path='/page1' component={Page1} />
                <Route exact path='/page2' component={Page2} />
    　　　　　　　　　 <Redirect from='/' to='/home' />
            </Switch>
        </HashRouter>
    </>
)

render(<App />, document.getElementById('root'))

    此时可以来回切换home、page1、page2三个页面

    接入redux 

    npm install -S redux react-redux // 安装redux相关依赖
mkdir models && cd models && mkdir stores actions reducers // 在src目录下创建redux相关的文件夹，并分别在目录下创建index.js
cd stores && touch index.js && cd ../actions && touch index.js && cd ../reducers && touch index.js // 分别创建index.js文件
    // src/models/actions/index.js
export const CREATE_TODO = 'CREATE'; // 增加一个todo
export const DELETE_TODO = 'DELETE'; // 删除一个todo
export const CREATE_TYPE = 'CREATE_TYPE'; // 添加操作
export const DELETE_TYPE = 'DELETE_TYPE'; // 删除操作
    // src/models/reducers/index.js
import {
    CREATE_TODO,
    DELETE_TODO,
    CREATE_TYPE,
    DELETE_TYPE,
} from '../actions'

export function todos(state = [], action) {
    switch (action.type) {
        case CREATE_TODO: {
            return [...state, { id: action.id, text: action.text, completed: false }]
        }
        case DELETE_TODO: {
            return [...state].filter(({ id }) => id !== action.id)
        }
        default: {
            return state;
        }
    }
}

export function operateCounter(state = { createCounter: 0, deleteCounter: 0 }, action) {
    const { createCounter, deleteCounter } = state;
    switch (action.type) {
        case CREATE_TYPE: {
            return { ...state, createCounter: createCounter + 1 }
        }
        case DELETE_TYPE: {
            return { ...state, deleteCounter: deleteCounter + 1 }
        }
        default: {
            return state;
        }
    }
}
    // src/models/stores/index.js
import { combineReducers, createStore } from 'redux'
import * as reducers from '../reducers'

const todoApp = combineReducers(reducers)
export default createStore(todoApp)

    修改src/index.js，里面的HOME，PAGE1，PAGE2组件应该分别抽离在不同的页面中

    // src/index.js
import React from 'react'

            <div className={styles.hohoho}>添加操作： {createCounter} 次，删除操作： {deleteCounter} 次</div>
            {todos.map(({ text, id }) => (<li key={id}>{`id:${id}-text:${text}`}</li>))}

    )
}
const mapStateToPropsHome = state => {

        dispatch({

    }
    return (

    )
}
const mapStateToPropsPage1 = state => {
    return {
        todos: state.todos,
    };
};
const Page1 = connect(mapStateToPropsPage1)(Page1Old);





const Page2Old = (props) => {
    const { todos = [], dispatch } = props;
    function onClick(id) {
        dispatch({
            type: DELETE_TODO,

                </li>
            ))}
        </>
    )
}
const mapStateToPropsPage2 = state => {
    return {
        todos: state.todos,
    };
};
const Page2 = connect(mapStateToPropsPage2)(Page2Old);






const App = () => (
    <Provider store={store}>
        <div className={styles.hohoho}>STAGE HOHOHO</div>
        <li><a href='#/home'>去home</a></li>

render(<App />, document.getElementById('root'))

    npm install -D @types/react @types/react-dom @types/react-router-dom @types/react-redux typescript ts-loader
    npm install -g typescript

    修改生成的tsconfig.json

    同时需要修改build/webpack.config.js，修改入口文件将原来的index.js改为index.tsx，添加resolve配置
