Understanding the concept of useSelector
useSelector is a hook provided by React Redux that allows functional components to extract and access data from the Redux store. It subscribes to the Redux store, and whenever the store is updated, the component re-renders to reflect the changes. Here’s a breakdown of how to use useSelector:
- Import the useSelector hook from the ‘react-redux’ library.
import {useSelector} from "react-redux";
- Call useSelector within your functional component, passing in a selector function.
const counter = useSelector(state => state.counter);
- The selector function defines which part of the Redux store state you want to extract and use within your component.
- useSelector returns the selected data from the Redux store, which you can then use within your component.
React Redux Hooks: useSelector and useDispatch.
State management is a major aspect of building React applications, allowing users to maintain and update application state predictably. With the introduction of React Hooks, managing state has become even more streamlined and efficient.
Among the most commonly used hooks for state management in React Redux are useSelector and useDispatch. In this article, we’ll explore how these hooks work and how they can simplify your React Redux development process.
