Modern redux

Creating the Root Reducer​ A Redux app really only has one reducer function : the “root reducer” function that you will pass to createStore later on. That one root reducer function is responsible for handling all of the actions that are dispatched, and calculating what the entire new state result should be every time.

Redux Toolkit is our recommended toolset for using Redux. It has functions that build in our suggested best practices, including setting up the store to catch mutations and enable the Redux DevTools Extension, simplifying immutable update logic with Immer, and more.19 Şub 2022

Yes, Redux is still popular . There are many alternatives, though I won’t claim one is necessarily better. Redux is a way for an app to manage complex states. In React, components have their own state, but they don’t have an easy way to access another components’ state (by design).

Redux simply provides a subscription mechanism which can be used by any other code. That said, it is most useful when combined with a declarative view implementation that can infer the UI updates from the state changes , such as React or one of the similar libraries available.
