Mastering Redux Toolkit Query | Tutorial for Beginners

Syncing your UI with a backend is where most apps get messy. Fetching, caching, invalidating, refetching: doing all of that by hand is endless boilerplate. RTK Query handles it for you, and I show you exactly how in the video, using a real to-do app backed by an Express server.

The same setup works in React Native, Vite, and Next.js, so you learn it once and use it everywhere.

What's inside

• Queries for fetching and mutations for creating and updating to-dos
• Auto-generated hooks like useGetTodosQuery with loading and error states built in
• Keeping a list, details, and edit screen in sync without passing props
• A simple Express.js backend so you see the full server-to-client flow
• Caching that updates every component automatically after a mutation
• Integration with Expo Router's file-based routing
