React Query (TanStack Query) is a library that manages server state, caching, and synchronization in React apps. Frontend engineers use it to eliminate boilerplate for data fetching, reduce loading states, and keep UI in sync with server. Learning time: 2–3 months. Salary impact: High; RQ is industry standard. Adjacent: React Advanced, REST APIs, State Management, Next.js.

什麼是 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.

❓ 常見問題

Do I still need Redux if I use React Query?
No, not for server state. RQ handles fetching, caching, and sync. Use local state (useState) or lightweight tools like Zustand for UI state. Redux is overkill.
What's the difference between React Query and SWR?
Both are great. RQ has more features (mutations, infinite queries, optimistic updates). SWR is simpler and lighter. Pick based on needs.
How does React Query handle caching?
RQ caches by query key. Default: data is fresh for 5 min, then stale. Fetching in background when stale. You tune staleTimes and revalidation policies.
Can I use React Query with GraphQL?
Yes, though Apollo Client is better optimized for GraphQL. RQ works with any fetch function (GraphQL, REST, gRPC).
How do I handle optimistic updates?
Use the onMutate hook to update the cache before the server responds. If the mutation fails, rollback the cache automatically.
