@tanstack/vue-query is a powerful data-fetching and caching library for Vue applications built on top of TanStack Query. It simplifies asynchronous data management by providing hooks and utilities for fetching, caching, synchronizing, and updating server state. Using Vue Query eliminates boilerplate code and ensures your application stays responsive with features like background updates, optimistic updates, and automatic retries. It's essentially a state manager specifically tailored for server-side data, deeply integrated with the Vue reactivity system.
