Remote data
Remote data is application data maintained outside a local client, typically by a server or external service, and accessed or synchronized over a network.
React in Depth
Remote data is application data retrieved from an external service or system rather than stored solely within the application.
- How it is used
- Supports shared, multi-user application experiences by moving data between a client and a remote server.
- How deep it goes
- Explains requests, responses, latency, security, and mocked-server behavior, but defers implementing production backend frameworks and databases.
- Examples
- Uses shared social posts, a local-versus-remote request flow, and an MSW intercept backend as concrete examples.
- What you can do after
- Apply it via MSW to build a React client against a realistic server boundary before implementing the production backend.
React Hooks in Action: With Suspense and Concurrent Mode
Server state is application data whose authoritative value is maintained by a remote server and synchronized to clients.
- How it is used
- Coordinates cached, deduplicated, and synchronized server data across React application views.
- How deep it goes
- Explains caching, background refetching, query status, mutations, and query-cache access without descending into networking internals.
- Examples
- Uses a bookings app, delayed json-server responses, Bookables navigation, loading indicators, and repeated users or bookables requests.
- What you can do after
- Operate/configure React Query to fetch, cache, refetch, and mutate server data while exposing request status.
