React Hooks are a useful new feature, and React Redux’s addition of It’s just easier since my component might have aĭescendent that is connected to Redux and therefore still need to be connected. Wrap my components in a Redux Provider and test them in the context of beingĬonnected to Redux anyway. While this reasoning is still valid to anĮxtent, I’ve since found that in tests and prototyping tools, I almost always This article recommended continuing to use the connect middleware instead of Like Storybook without having to connect the component. You can then test the component or prototype it in tools While the Redux Hooks have many benefits, there is one benefit of usingĬonnect instead of the Redux Hooks, and that is that it keeps your componentĭecoupled from Redux. In TypeScript projects, IĬreate my own useSelector that is typed to my store, and then I get The Redux Hooks, on the other hand, are just regular hooks thatĭon’t modify the public interface of your component. The selector functions that you write will be.
Create a src/features/counter/Counter.js file with aWe can read data from the store with useSelector, and dispatch actions using useDispatch. If you are using TypeScript,Ĭorrectly defining the types of connected components can be quite a chore for React components can read data from the Redux store using the useSelector hook from the React-Redux library. Now we can use the React Redux hooks to let React components interact with the Redux store. Props come from Redux and which are passed in. This can make it difficult to determine in the component which With connect, you are wrapping your component and injecting The main benefit of using the Redux Hooks is that they are conceptually simpler Hooks aligns with this recommendation and provides other key benefits Over using class-based components and higher-order components.

Recommendation for new code is to generally prefer function components and Hooks While there is no need to race off and convert all your existing code, our Keep supporting class components for the foreseeable future. We intend for Hooks to cover all existing use cases for classes, but we will Using function components and hooks when possible. Previously possible, and the community is clearly moving in the direction of They allow for using function components in ways that weren’t Since come to prefer using the Redux Hooks. Using selectors in useSelector to pull data from. Originally recommended sticking with connect over the Redux Hooks but have Enforces that all useSelector hooks use named selector functions.
