使用redux调试器

1.将调试器放到谷歌浏览器

2.代码

import { applyMiddleware, legacy_createStoreas as createRoot } from 'redux'
//redux中间件
import thunk from 'redux-thunk'
//数据
import reducer from './reducer'

//1.调试器的配置
import { composeWithDevTools } from 'redux-devtools-extension'

//2.将中间件用composeWithDevTools包裹起来
const store = createStore(reducer, composeWithDevTools(applyMiddleware(thunk)))

export default store
