combineReducers的使用

作用: 将各个小的reducer整合成一个大的reducer; 方法: combineReducers ( { header : headerReducer , body : bodyReducer } ) ; 注意点: 使用时, 普通对象从redux中引入combinReducers, immutable对象从redux-immutable中引入, 如下: 1, 普通对象: import { combinReducers } from 'redux'; 2, immutable对象: import { combinReducers } from 'redux-immutable'; 来源： CSDN 作者： jiuyehengxia 链接： https://blog.csdn.net/jiuyehengxia/article/details/104044272

Original Question asked on 28/11/2019 I am trying to learn Higher Order Components but struggling to get a Higher Order Component connected to the redux store and router. Hoping that someone can help with a Higher Order Component type compilation problem I am struggling with relating to mapStateToProps .

快速学习ReactJS-简介

2.2、ReactJS简介 官网： https://reactjs.org/ 官方一句很简单的话，道出了什么是ReactJS，就是，一个用于构建用户界面的JavaScript框架，是Facebook开发的一款的JS框架。 ReactJS把复杂的页面，拆分成一个个的组件，将这些组件一个个的拼装起来，就会呈现多样的页面。ReactJS可以用 于 MVC 架构，也可以用于 MVVM 架构，或者别的架构。 ReactJS圈内的一些框架简介： Flux Flux是Facebook用户建立客户端Web应用的前端架构， 它通过利用一个单向的数据流补充了React的组合视图组件，这更是一种模式而非框架。 Redux Redux 是 JavaScript 状态容器，提供可预测化的状态管理。Redux可以让React组件状态共享变得简单。 Ant Design of React 阿里开源的基于React的企业级后台产品，其中集成了多种框架，包含了上面提到的Flux、Redux。 Ant Design提供了丰富的组件，包括：按钮、表单、表格、布局、分页、树组件、日历等。 来源： CSDN 作者： cwl_java 链接： https://blog.csdn.net/weixin_42528266/article/details/104031056

实现mini版redux 1. 理解redux模块 1). redux模块整体是一个对象模块 2). 内部包含几个函数 createStore(reducers) // reducers: function(state, action){ return newState} combineReducers(reducers) // reducers: {reducer1, reducer2} 返回: function(state, action){ return newState} applyMiddleware() // 暂不实现 3). store对象的功能 getState() // 返回当前state dispatch(action) // 分发action: 调用reducers()得到新的总state, 执行所有已注册的监听函数 subscibe(listener) // 订阅监听: 将监听函数保存起来 2. 实现代码: src/libs/redux/index.js /* 创建store对象的函数 */ export function createStore(reducer) { // 内部管理的state let state // 用来缓存监听的数组容器 const listeners = [] // 初始调用reducer得到初始state值 state =
