tanstack-query

You can cache fetched data and manage server-state in React using useQuery hooks. TanStack Query handles background refetching and intelligent invalidation to reduce boilerplate and prevent stale data across UI components.

Server-state is data fetched from a remote server that requires active synchronization to avoid becoming stale. TanStack Query manages server-state by handling caching, background refetching, and invalidation, reducing the boilerplate needed compared to storing remote data in standard client state.

Yes, TanStack Query supports SSR hydration and spans React, Vue, Solid, Svelte, and Angular. It provides declarative data fetching and mutation APIs to seamlessly handle server-state across these various frameworks.

To handle mutations in TypeScript applications, use the useMutation API. TanStack Query enforces typed hooks for robust data flows and supports optimistic updates to immediately reflect changes in complex UIs before server confirmation.

The best way to keep paginated data fresh is through intelligent query invalidation. TanStack Query coordinates server-state by enforcing stable query keys, allowing you to precisely invalidate cached queries and trigger background refetching for updated data.
