In traditional Redux, fetching data required writing 4–7 different pieces of code for a single API call, including action creators, thunks, and loading/error reducers. RTK Query collapses this into a single centralized API slice that handles the heavy lifting out of the box.
Manual creation of async thunks, actions, and reducers for every API call.
No built-in caching, causing redundant network requests.
Tedious management of loading and error states.
Difficult data synchronization when multiple components depend on the same API data.
Provides built-in caching, invalidation, and automatic background refetching.
Generates React hooks (useQuery, useMutation) automatically for API endpoints.
Simplifies loading, success, and error state management with zero boilerplate.
Keeps data consistent across components without manual synchronization.
By handling caching, refetching, and state updates automatically, RTK Query dramatically reduces boilerplate and improves performance in Redux-based applications.
