1.弹出项目配置

npm run eject
此处注意,若弹出项目配置失败,请先执行以下两行代码(我的项目执行上一句都会报错,所以都会执行)

1.git add .
2.git commit -m "init"
  

2.安装装饰器所需依赖

npm install --save-dev babel-plugin-transform-decorators-legacy
  

3.安装应用配置

npm install @babel/plugin-proposal-decorators


4.安装mobx和mobx-react


1.npm install mobx --save
2.npm install mobx-react
 

5.配置package.json(直接在最下方加上就行)

"babel"{
    "plugins":[
    [
      "@babel/plugin-proposal-decorators",
      {
          "legacy":true
      }
    ],
    [
      "@babel/plugin-proposal-class-properties",
      {
          "loose":true
      }
      ]
      ],
     "presets":[
     "react-app"
     ]
},
  

6.环境测试

  1.新建store.js模拟本地数据库
import {observable,action} from "mobx";
class Store {
    id = Math.random();
    @observable title="飞飞";
    @observable finished = false;
    @action cTitle =()=>{
        this.title="麦扣扣"
    }
}
export  default  new Store()
 

  2.新建App.js进行调用

import React, { Component } from 'react';
import Store from "./store";
import {observer} from "mobx-react"
 
@observer
class App extends Component {
  render() {
    return (
      <div>
        this is Index
        <p>{Store.id}</p>
        <p>{Store.title}</p>
        <button onClick={Store.cTitle}>测试</button>
      </div>
    );
  }
}
export default App;
