01. Typed Hooks

Section 1 of 2

Create typed versions of useSelector and useDispatch for better type inference.

typescript

import { useDispatch, useSelector } from 'react-redux';
import type { RootState, AppDispatch } from './store';

// Use throughout app instead of plain hooks
export const useAppDispatch = useDispatch.withTypes<AppDispatch>();
export const useAppSelector = useSelector.withTypes<RootState>();

// Usage with full type safety
const dispatch = useAppDispatch();
const user = useAppSelector((state) => state.user);
