This article mainly explains "there is no middleware in redux in react". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "there is no middleware in redux in react".

Redux in react has middleware, because the data in redux requires asynchronous requests, so middleware is needed to complete asynchronous requests in redux; middleware can expand redux applications, when the component triggers an action, action will be processed by the middleware first, and then transferred to reducer after middleware processing.

The operating environment of this tutorial: Windows10 system, react17.0.1 version, Dell G3 computer.

Does redux have middleware in react?

Redux has middleware in react

Because we have a lot of data in redux that require asynchronous requests, we need middleware to help us complete asynchronous requests in redux.

Middleware is actually a function, and middleware allows us to extend redux applications. Specifically, it is reflected in the processing ability of action. When a component triggers an action, the action will be preferentially processed by the middleware. When the middleware has finished processing, the middleware will pass the action to the reducer and let reducer continue to process the action.

Join the redux workflow of middleware

Redux common middleware (redux-saga)

Redux-saga is more powerful than redux-thunk because redux-saga can extract asynchronous operations from the Action Creator file and put them in a separate file

How to use redux-saga?

Download:

Npm install redux-saga

Create redux-saga middleware

Import createSagaMiddleware from 'redux-saga' const sagaMiddleware = createSagaMiddleware ()

Register for sagaMiddleware

CreateStore (reducer, applyMiddleware (sagaMiddleware)) Thank you for your reading, the above is the content of "there is no middleware in redux in react". After the study of this article, I believe you have a deeper understanding of whether there is middleware in redux in react, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
