The original address: https://medium.com/@dan_abramov/you-might-not-need-redux-be46360cf367 People always choose redux before they really need redux. The starting point may be, "even if I don't need it now, I'm going to use it for the future scalability of the project." However, after developing the handwriting code, I found the inconvenience: "Why do I need to a

What's the problem redux to solve?As JavaScript single-page application development becomes more complex,JavaScript needs to manage more state thanever. These states may include server responses, cached data, local build data that has not been persisted to the server, and UI state, such as the active route, the selected label, whether the load dynamic or pager is displayed, and so on.Managing the changing state is very difficult. If the change of one

As we all know, one of react's pain points is communication between components that are non-parent-child, and its official documentation is not taboo: For communication between, there is a parent-child relationship, you can set up your own global event System. Subscribe to events in Componentdidmount (), unsubscribe in Componentwillunmount (), and call SetState () when you receive an Event. Redux can be seen as the "global Event System",

With the fire of react, the flux architecture followed fire, Redux was the leader in the library of flux architecture, and more and more developers used React+redux to develop applications. Indeed, REACT+REDUX+WEBPACK+BABEL+ES6, this is a highly productive combination. The one-way flow from the flux architecture makes the logic and data flow of applications cont

---restore content starts---1. Function structure:CDN Technology since its inception in 1998, with the rapid development of the Internet, its technology has been continuously evolving and improving, but the basic CDN function architecture in about 2003 years has basically formed and stabilized. Functionally, a typical CDN system architecture consists of a distribution service system, a load balancing system

readme.md Preface began to learn react, on the Internet to find some articles, read the official website of some documents, then feel react started or quite simple, and then on the Internet to find a react actual combat practicing project, personally learned that this project is suitable for beginners or advanced friends Practice, here to share with you Project Introduction The project similar to the public comments, the United States and other O2O software, similar functions, but becau

Welcome to the Guide and discussion:)　　Objective　　　This article does not involve in-depth knowledge, just on the conceptual level and a simple example explaining how redux-observable works.Redux-observable, is a middleware library for redux. It automatically responds to the actions we dispatch and executes the corresponding functions, allowing us to separate complex asynchronous functions into some epic fun

Simple descriptionThis article is my study react one months of summary, starting from the basics (including editor settings, build tools), step by step toward react development. Believe me, after reading this article, follow the steps of the article go, to ensure that you get started react and love react, Master React-router,redux. This article follows the principle of being more basic.First, the editor startsDescribed here is the sublime TEXT3 config

In the previous lesson we created a reducer so can handle the actions, adding a new to-do, and toggling an existing to-d O. Right now, the code to update the to-do item or to create a new one are placed right inside of the to-dos reducer.This function was hard to understand because it makes us-different concerns, how the to-do's array is updated, and how Individual to-dos is updated. A problem unique to Redux. Any time a function does too many things,

Using Redux in React applicationsLike Flux, Redux also needs to register a callback function store.subscribe(listener) to get the update of state, and then we'll listener call it inside setState() to update the React component.Redux officially provides react-redux to simplify the binding between react and Redux, elimin

The previous article shows the basic use of redux, you can see Redux is very easy to use, not limited to react, can also be used in angular, Vue and other frameworks, as long as the need to redux the design of the idea of the place, you can use it.This article mainly explains the use of redux in react, the first is the

because it's not necessary.Three main reasons for this view Most of our state management code is concerned with merging and transforming the REST resources from the scattered to the data that apply to our UI. Many complex state management is the orderly acquisition of all asynchronous data (sagas, middleware, thunks, and so on.) Actually, in addition to this part of the above, we use our own React state can be a good fit for our daily business. About GRAPHQL and

Recently in the study of the front-end of the major popular framework, the main study of Vue.js and react.js, the previous time with Vue.js + Uikit to achieve the clone version of v2ex, and recently with React.js + redux + bootstrap to achieve Rubych The clone version of ina, two projects all support responsive layouts. I have to say that this is an effective way to learn new Knowledge. These two projects are more appropriate to learn vue.js and react

First, in Reducer, the returned state must be a completely new object , otherwise redux will not execute the listening method, because Redux will assume that state has not been updated and there is no need to re-render the view.Examples of problems that occur:Const user= (state={name= ", age=0},action) = {switch( action.type) { case ' Change_name ': state.name= ' Zhangsan ';
