React Redux Hooks: useSelector and useDispatch
October 18, 2023 - In this example, the useSelector hook is used to access the value of the **counter** property in the Redux store. Examples of using useSelector hook in React components: Here are a few examples of how the useSelector hook can be used in React components:

January 22, 2026 - A selector function can be used anywhere you have access to the entire Redux root state value. This includes the useSelector hook, the mapState function for connect, middleware, thunks, and sagas.

Introduction on React-Redux using Hooks ( useSelector & useDispatch ) | by Alex Mendes | Medium
November 25, 2019 - Until now, all of our code was very similar to using React and Redux with no hooks, but now things are going to start changing a little bit and we are going to take away some of the code abstraction of writing Redux code and make possible to read and dispatch (send) data from the store a lot easier from any functional component. Letโs start by importing useSelector from the react-redux library.

useSelector vs connect (react-redux)
February 1, 2021 - React-redux hooks like useSelector() and the connect() can have the same outcomes. The main difference between them is their ability to nudge (guide) the way you write your components.

Hooks in Redux useSelector and useDispatch - React
June 22, 2024 - The useSelector hooks allow you to extract data or the state from the Redux store using a selector function. It is equivalent to the mapStateToProps argument used in the connect() function conceptually.

August 1, 2024 - So, selectors can return values from the Redux store state, and also return derived values based on that state as well. Let's read the array of todos into our <TodoList> component. First, we'll import the useSelector hook from the react-redux library, then call it with a selector function as ...

May 24, 2021 - Only the data that is needed to be long-lived and globally available should make into Redux state. From this perspective, ease of use becomes our enemy. As React's useState hook and Redux's useSelector hook offer similar API surfaces, developers tend to put most of the state to their Redux state instead of picking only necessary ones.

useSelector and useDispatch: Redux | by Dhrubo Dh | Medium
May 25, 2021 - Now in the app components, instead of using the tradition connects, mapStateToProps, and mapDispatchToProps, I imported to hooks that were provided by redux: useSelector and useDispatch . The names are pretty self-explanatory, useDispatch give us a dispatch, which I can use to dispatch actions.

April 22, 2022 -
we are creating a new object every time from useSelector hook when getting the state in the component
```
const {
isEmbed,
isMobileView,
isUserLoggedIn,
boardDetails: {
membershipType,
boardThemeCustomColors,
boardId,
boardName,
},
} = useSelector(
({
auth: { isUserLoggedIn },
activeBoard: { boardDetails },
visibility: { isMobileView },
embed: { isEmbed },
}) => {
const board = boardDetails || {};
const location = (board.locations || [{}])[0].searchedLoc;
return {
isEmbed,
isMobileView,
boardDetails: { ...board, location },
isUserLoggedIn,
};
}
); Top answer 1 of 4

see Deriving Data With Selectors - you should use a memoised selector, otherwise your component will rerender after every action dispatched.

As the other comments have pointed out, this is buggy. useSelector relies on strict === equality checks by default to determine when to re-render the component . You're returning a new object reference every time. That means this component will re-render after every dispatched action, regardless of whether the relevant data actually changed or not! Your options are: Use a memoized selector ( https://redux.js.org/usage/deriving-data-selectors ) Use the shallowEqual comparison function as the second arg. However, since you're returning a new reference for boardDetails every time, this probably won't work in your situation. So, a memoized selector seems like the best choice here.
