React Query Data

React Query is a data-fetching and caching library for React that eliminates the complexity of managing server state. Instead of manually writing fetch-dispatch-setLoading-setError code, you declare what data you need, and React Query handles fetching, caching, background revalidation, and synchronization. The library uses a simple key-value cache backed by query keys. When you fetch the same data twice, React Query returns cached results instantly and revalidates in the background. It's especially powerful for apps with lots of API calls and shifting data states.
