The “vanilla” store implementation you get by calling createStore only supports plain object actions and hands them immediately to the reducer.
However, if you wrap createStore with applyMiddleware, the middleware can interpret actions differently, and provide support for dispatching async actions. Async actions are usually asynchronous primitives like Promises, Observables, or thunks.
Redux-Observable is a middleware for Redux which handles cancellation and many other asynchronous side effects by using reactive programming. … RxJS and Most.js are two libraries for reactive programming with which you can handle streams of actions in different ways. … In the following examples, Most.js will be used.
Async generators are new in JavaScript, and I believe it is a very remarkable extension. It provides a simple, easy to use but very powerful tool for splitting programs into smaller parts, making…
I found middlewares both easy to understand and a useful addition to my Redux toolbox. And I think after reading the source code for the following 3 popular middlewares you'll feel that way too.
If you have built Node.js apps using frameworks like Express.js, you are probably aware of functions called “middlewares” and how they work. Redux brings that same concept to the front-end…
