Summary
TanStack Query (formerly React Query) is a powerful asynchronous state management library for React that handles server-state fetching, caching, synchronization, and updates. It eliminates the need for manual data fetching boilerplate and provides built-in features like background refetching, optimistic updates, pagination, and intelligent cache management.
When to Use
Use TanStack Query when:
- Fetching data from REST APIs, GraphQL, or tRPC endpoints
- Need automatic background refetching and cache invalidation
- Building real-time dashboards with polling or websocket data
- Implementing infinite scroll or pagination
- Require optimistic UI updates for mutations
- Managing complex server-state synchronization
- Need offline support with cache persistence
- Building applications with frequent data updates
