TanStack Query (formerly React Query) is a TypeScript library for asynchronous state management that handles fetching, caching, synchronizing, and updating server state in web applications. It provides declarative hooks and adapters for React, Vue, Solid, Svelte, Angular, Lit, and Preact, with built-in caching, retries, deduplication, and background refetching.

Use cases

• fetch and cache API data in React
• manage server state in a web app
• implement infinite scroll and pagination
• refetch data on window focus
• handle optimistic updates after mutations
• deduplicate duplicate API requests
• prefetch data for routes
• replace Redux for async data

When to choose

• your app relies heavily on remote/server data that needs caching and revalidation
• you want retries, deduplication, and background refetching out of the box
• you use React, Vue, Solid, Svelte, Angular, or Lit and want typed async state hooks
• you need pagination, infinite queries, or offline mutation queues

When to avoid

• you only manage local client-side UI state with no server data
• you need a full global state store for complex client state (combine with a state library)
• your project cannot adopt its opinionated defaults and cache lifecycle
• you work outside the supported JS frameworks
