React Query

Data-fetching and state management library designed to handle server state in web applications.

Overview

TanStack Query (formerly React Query) is a data-fetching and state management library designed to handle server state in web applications. It provides powerful tools for fetching, caching, synchronizing, and updating asynchronous data across multiple frontend frameworks including React, Vue, Solid, Svelte, Angular, and Lit.

The library solves common challenges developers face with server state: caching, request deduplication, background refetching, garbage collection, and keeping data fresh. It comes with sensible defaults out of the box—including automatic retries, stale-while-revalidate patterns, and window-focus refetching—while remaining highly customizable as applications grow.

TanStack Query eliminates the need for complex state management boilerplate by providing declarative APIs for queries and mutations, making applications feel faster and more responsive while reducing bandwidth usage.
