Có cách nào quản lý state hiệu quả trong Next.js?

It depends on the type of state you're managing.

• Local component state:** Use useState or useReducer.
• Shared client state:** For small applications, the Context API is usually enough. For larger applications, libraries like Zustand or Redux Toolkit provide better scalability and performance.
• Server state (API data):** Use TanStack Query or SWR for caching, synchronization, and background updates.
• URL state:** In the App Router, use searchParams on the server or useSearchParams on the client.

For most Next.js applications, a combination of Server Components for data fetching and a lightweight client-state library like Zustand works well. I also recommend keeping state as local as possible and introducing global state only when it's truly shared across multiple parts of the application.
