To manage server-state in React, you can centralize fetching, caching, and synchronization to reduce boilerplate. Using a queryClient with configurable stale times and background refetching keeps your application data predictable and fresh with minimal manual work.

Server-state management works across Vue, Svelte, Solid, and Angular projects using a consistent API. You apply the same queryFn patterns, query keys, and caching logic to fetch and synchronize data regardless of the framework you choose.

The best way to implement optimistic updates and pagination is by using built-in features for infinite queries and fine-grained invalidation. This approach automatically updates the UI before the server response arrives and invalidates query keys to refetch modified data.

To set up data-fetching, install the library, create a QueryClient, and wrap your application with the QueryClientProvider. You then call useQuery by passing a queryKey to identify the data and a queryFn to fetch it.

Stale-while-revalidate caching improves user experience by immediately displaying cached data while fetching fresh data in the background. This mechanism keeps your server-state synchronized and up-to-date without forcing users to wait for network requests to complete.

You do not need to manually handle retries and stale times because the system provides configurable options for both. Setting these parameters allows you to control background refetching behavior and automatically retry failed requests for robust data flows.
