What is it?

TanStack Query is an async state management library that handles fetching, caching, synchronizing and updating server state in web applications. It is protocol-agnostic, so it works with REST, GraphQL, or any promise-based data source.

The library covers common data-fetching needs such as caching, background refetching, pagination and infinite scroll, mutations, dependent queries, prefetching and request cancellation. It also supports React Suspense. The core logic lives in a framework-agnostic package, with official adapters for React Query, Vue Query, Svelte Query and Solid Query.

The project is written in TypeScript and is part of the wider TanStack ecosystem, which includes Router, Table, Form and Virtual.
