TanStack Query (React Query) Skill

You can manage server state in React by using declarative hooks for data fetching, caching, and synchronization. This approach eliminates complex boilerplate by automatically handling background refetching and keeping the UI in sync with the server.

TanStack Query works with REST APIs, GraphQL, and tRPC for data fetching. It manages asynchronous server state across these protocols by standardizing caching, updates, and background synchronization within your React application.

The best way to implement pagination and infinite loading is through a dedicated server state management library. This approach handles complex data fetching patterns natively, ensuring your React dashboard loads data efficiently without manual cache tracking.

You can perform optimistic updates by configuring your mutation logic to instantly update the UI before the server responds. This technique provides a seamless user experience by immediately reflecting anticipated changes while managing background synchronization.

You should use a dedicated caching library when your application requires automatic background refetching, cache invalidation, and complex synchronization. It becomes necessary when standard React state fails to efficiently manage asynchronous server data updates.

To fetch user data from an API endpoint like '/api/users/1', you set up a basic query using a declarative hook. This defines your data needs simply while the library automatically handles the caching and fetching logic.
