在"reducers"文件夹中,创建一个名为"index.js"的文件,用于将所有的reducer函数组合成一个根reducer。可以使用Redux提供的"combineReducers"函数来实现这一点。 在"actions"文件夹中,创建一个名为"index.js"的文件,用于将所有的action创建函数导出。可以使用Redux提供的"bindActionCreators"函数来简化这一过程。 ...
reducer使用switch case语句进行action类型判断,当action很多时候,reducer内容就不那么直观了。redux-actions简化了reducer和action的联系 三、基本使用 1、创建action/actionCreator.js import { createAction } from 'redux-actions'; export const addnum= createAction('ADDNUM') 2、组件中引入使用 import React,{Co...

This lesson demonstrates that you can get a small performance gain by removing AJAX calls that feed into redux from the react/hooks lifecycle. In this video we see a 100ms reduction in the time it takes to initiate our AJAX call to load AJAX rates when we move it outside ofuseEffectand ...

在React + Redux中,reducers是用于管理应用程序状态的纯函数。它们接收先前的状态和一个动作对象作为参数,并返回一个新的状态。为了实现良好的策略,我们可以考虑以下几点: 单一职责原则:每个reducer应该只负责管理一个特定的状态片段。这样可以使代码更加清晰和可维护。 拆分和组合:将大型的reducer函数拆分成多个小的reduc...
Alternatively, you can use theuseDispatchhook to dispatch actions directly in the component. // src/components/widget/widget.tsximport{useDispatch}from'react-redux';import{loadAndSelectChannel}from'src/actions/channels';typeProps={channelId:string;}exportdefaultfunctionWidget(props:Props) {constdispatch...
