redux 配置（谷歌tool）

redux 配置tool
index.js

import {createStore} from 'redux';
import reducer from './reducer';
const store = createStore(reducer,
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
    )
export default store;

安装 redux-thunk 后配置 tool

import {createStore,applyMiddleware,compose} from 'redux';
import reducer from './reducer';
import thunk from "redux-thunk";
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__?
window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({}):compose
const enhancer = composeEnhancers(applyMiddleware(thunk));
const store = createStore(reducer,enhancer)
export default store;
