One of the most common issues when using Redux with Next.js is . Because Next.js renders twice (first on the server, again on the client), if the Redux store initial state differs between the two renders, you get hydration errors.

Do you need across page reloads (Redux Persist)?

Now you can read data from the store and dispatch actions inside your interactive client-side views. Create a counter component at src/app/counter/page.tsx : typescript

return ( <div> <button onClick=() => dispatch(decrement())>-</button> <span>count</span> <button onClick=() => dispatch(increment())>+</button> </div> );

interface CounterState value: number;

Using these typed hooks ensures better IntelliSense and catches type errors early.
