React Query (TanStack Query)
Part of the Frontend Developer Roadmap
In short
A library specifically for server-state — fetching, caching, background-refetching and syncing API data — that eliminates most manual loading/error/cache logic.
How to learn this
- 1Replace a manual `useEffect` + `fetch` pattern with `useQuery`.
- 2Learn how automatic caching and refetch-on-focus change your app's behavior.
- 3Use `useMutation` for POST/PUT/DELETE requests with cache invalidation.
