# create-react-app 搭建 有ReactRouterDom 和 Mobx 项目 #

1.  下载 create-react-app

npm i create-react-app -g

1.  创建react 项目

create-react-app qiphon-demo
    
    cd qiphon-demo

1.  自己修改webpack之类的配置需要执行npm run eject弹出配置文件

yarn eject

之后webpack配置项会暴露出来，可以在package.json 中进行配置

安装依赖，并配置Babel

"babel": {
        "presets": [
          "react-app"
        ],
        "plugins": [
          [
            "@babel/plugin-proposal-decorators",
            {
              "legacy": true
            }
          ]
        ]
      },
      "devDependencies": {
        "@babel/plugin-proposal-decorators": "^7.3.0",
        "@babel/plugin-transform-react-jsx": "^7.3.0",
        "@babel/plugin-transform-react-jsx-self": "^7.2.0",
        "@babel/plugin-transform-react-jsx-source": "^7.2.0"
      }

1.  安装 mobx / mobx-react

yarn add mobx mobx-react -S

src目录下面创建 store 文件

import { action, observable } from 'mobx'
    
    class Store {
        @observable name= "qiphon"
        @action doSomething(val){
            this.name = val
        }
    }
    
    // 一定要new 一下
    export default new Store()

入口文件引入Store

import React from 'react';
    import ReactDOM from 'react-dom';
    import App from './App';
    import * as serviceWorker from './serviceWorker';
    import { Provider } from 'mobx-react'
    import Store from './store/index'
    
    ReactDOM.render(   
        <Provider Store={ Store } ><App /></Provider>
        , document.getElementById('root'));
    
    // If you want your app to work offline and load faster, you can change
    // unregister() to register() below. Note this comes with some pitfalls.
    // Learn more about service workers: https://bit.ly/CRA-PWA
    serviceWorker.unregister();

1.  其他页面引入 或使用 Store

import React , { Component } from 'react'
    import { inject, observer } from 'mobx-react'
    
    import Foot from '../components/footer'
    
    @inject("Store") @observer
    class Index extends Component {
        componentDidMount(){
            console.dir(this.props.Store)
        }
        render(){
            return (
                <div className="home">
                    <div>store { this.props.Store.qiphon }</div>
                    <h1><a href="/news">i'm Home . touch me to news center</a></h1>
                    <Foot />
                </div>
            )
        }
    }
    
    export default Index

1.  配置路由

yarn add react-router-dom -S

路由文件配置

import React, { Component } from 'react';
    import { Switch, Route, BrowserRouter, Redirect } from 'react-router-dom'
    
    import Index from './routes/index'
    import News from './routes/news'
    class App extends Component {
      render() {
        return (
          <BrowserRouter>
            <Switch>
              <Route exact path="/" component={Index} />
              <Route exact path="/news" component={News} />
              <Redirect from="*" to="/" />
            </Switch>
          </BrowserRouter>
        );
      }
    }
    
    export default App;
