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

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

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;

Why use react also need to use other framework to match?The core of react is the performance of the component-defined interface, which is a front-end library of the view layer, and we usually ne
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
State management is an integral part of building a single page application, and it is also a point of knowledge that is worth taking time to learn. React officially recommends that we use Redux to manage our react applications, as well as provide redux documentation for us to learn, with the Chinese address http://cn.redux.js.org/index.htmlObjectiveAlthough the official documentation says it takes only a fe

If you pretend to be forced, please take me to fly!Once upon a time, I heard that react only responsible for the UI, saying that angular code is like writing back end, now it seems, react win in the feelings;I think there is no need to always compare react and angular, angular is a relatively complete set of chatty framework, and react is really only responsible for the UI, just a lot of the concept of things, you need to construct React more like to build a react as the main line of the ecology
