What is to be said here is a redux in the react of the application of the problem, talk about Redux,react-redux,redux-thunk,redux-actions,redux-promise, Redux-sage the effects o
My own understanding redux is similar to the Vuex in Vue, is a data manager, say, we start from the classic counter case to explain
Implementing counters using Redux
Create the following react project, I used to put each module block, only so many files, of course you can also write in a JS file, this is not the focus
First, let's look at the entry file for the project Index.js

Redux-saga is a middleware that manages asynchronous operations of Redux applications. Its functions are similar to redux-thunk + async/await, it stores all asynchronous operation logic in one place for centra
React-Redux and parse xreact-redux
I have been exploring React-related things before. I have a SPA project on hand, so I am going to try the water on Redux. Redux is not associated with React itself. It is a common Javscript App module used for App State management. To use Redux
With the development of the Internet, users pay more attention to the browsing speed and effect of the Web site, but because of the proliferation of netizens, the network access path is too long, so that the quality of access of users is seriously affected. Especially when the link between the user and the website is congested with large traffic data, the poor quality of access is an urgent problem for the region with rapid increase of internet users. How to enable users everywhere to make high-

Today, we are going to talk about the knowledge point of customizing the Redux middleware. This section is very abstract, especially the definition principle of middleware, the multi-layered function nesting and concatenation, need very strong logical thinking ability to completely digest absorption. But I'll say a few more words, so don't worry.ExampleAn example is the offici
Eco-SystemRedux is an individual small-scale library, but its related content and APIs are carefully selected, enough to derive a rich toolset and a scalable ecosystem.If you need a list of all the contents of Redux, we recommend that you move to Awesome Redux. It contains examples, boilerplate code, middleware, tool libraries, and many other related content. To learn React and

It tells us what we can do. The returned result is a simple function, which requires two parameters: state and action. state is a public variable value, and action is used to determine what operations the type condition performs;

Last week took an amateur time to see the redux, just beginning a little uncomfortable, a bit in the action, Reducer, store and middleware so many new concepts.After some understanding, found that Redux's one-way data in the pattern is relatively easy to understand, combined with the redux one-way data flow model, many concepts are relatively clear.The following redux
