How are react hooks used in react redux?


Asked by Adeline Cruz on Dec 10, 2021 React



With React Hooks' growing usage, the ability to handle a component's state and side effects is now a common pattern in a functional component. React Redux offers a set of Hook APIs as an alternative to the omnipresent connect () Higher-Order Component.
Moreover,
React Redux recently released version 7.1, which includes long awaited support for React Hooks. This means that you can now ditch the connect higher-order component and use Redux with Hooks in your function components. This post will take a look at how to get started using Redux with Hooks and then explore some gotchas of this approach.
In respect to this, React Hooks provide an alternative to writing class-based components by allowing us to easily handle state management from functional components. If you noticed, when explaining the React Context API, we needed to wrap our content in a Consumer component and then pass a function as a child just so we could access (or consume) our state.
Likewise,
Well, useMemo is a React Hook, which can only be called inside components, meaning that our Redux store cannot access it. We can solve this by using Reselect.
Subsequently,
With this our redux setup is complete, we can now access the redux store from the functional components using react hooks. The useSelector hook is similar to mapStatetoprops by using this hook we can access the entire redux store state. The useSelector hook will also subscribe to the redux store.
