useQuery
useQuery is a TanStack Query hook for asynchronously fetching and caching data while exposing its data, status, and error state.
React Hooks in Action: With Suspense and Concurrent Mode
useQuery is a React Query hook that fetches asynchronous data and returns its data, status, and error state while managing cached results.
- How it is used
- Fetches and caches server state so shared views remain responsive during navigation and avoid repeated loading indicators.
- How deep it goes
- Explains provider setup, query keys, returned state, cache reuse, background fetching, and an experimental Suspense option, without implementation internals.
- Examples
- Demonstrates bookables, bookings keyed by identifiers and dates, cached edit-form data, loading states, errors, and Suspense.
- What you can do after
- Build responsive data-driven components with React Query, shared caching, query-specific keys, status handling, and cached initial data.

React in Depth
useQuery is a TanStack Query hook that declares and retrieves asynchronously fetched data for a component.
- How it is used
- Declares component-level server-data queries and exposes results for rendering.
- How deep it goes
- Explains query functions, cache-oriented keys, loading state, and asynchronous data without covering hook internals.
- Examples
- Uses customer lists, individual customers, paginated results, name searches, and a loading branch.
- What you can do after
- Apply it via TanStack Query to fetch, identify, and render asynchronous data in a component.
