Redux常用方法

action创建函数

const addTask = (text)=> {
  return {
    type: ADD_TODO,
    text
  }
}
module.exports={addTask};

combineReducers

• 合并多个reducer，返回一个对象

import {combineReducers} from 'redux';
function todos(state = [], action) {
     ...
     return state;
}
export default combineReducers({
    todos
});

createStore / applyMiddleware

• createStore()创建的redux store 只支持同步数据流
• 引入applyMiddleware()可以处理异步请求

import {createStore,applyMiddleware} from 'redux';
import reducer from './reducers';
import middle from './middleware';
const Middleware = applyMiddleware(middle);
let store = createStore(reducer, Middleware);
