React 和 Redux 结合 1

React依赖：

"devDependencies": {

"babel-core": "^6.26.0",

"babel-loader": "^7.1.2",

"babel-plugin-transform-object-rest-spread": "^6.26.0",

"babel-preset-env": "^1.6.1",

"babel-preset-react": "^6.24.1"

},

"dependencies": {

"classnames": "^2.2.5",

"react": "^16.1.1",

"react-dom": "^16.1.1"

}

第一步，创建reducer文件下的index.js
第二步,在main.js中创建store--{createStore}
第三步，共享store--{Provider}
让所有下辖的组件都可以使用store
第四步，更改app组件
1）引入connect组件
2）export default connect() (app); 装饰者模式--将app装饰后暴露
