To manage state in Next.js 15 client components, use the Context API with strategically nested providers to ensure efficient state sharing. This approach maintains a maintainable component architecture while preventing unnecessary re-renders.

The best way to fetch data client-side using TanStack Query is to implement data fetching and mutations within your components, then wrap the asynchronous logic in Suspense boundaries to smoothly handle loading states.

Use Server Components versus Client Components based on interactivity needs. Server Components handle static rendering and initial data fetching efficiently, whereas Client Components are required for state management and user interactivity.

To prevent unnecessary re-renders in React components, apply performance optimization techniques like useCallback and component memoization. These methods ensure your application maintains optimal rendering efficiency during state updates.

Handle loading and error states by wrapping asynchronous components in Suspense boundaries to display fallback UI during data fetching, and use Error Boundaries for robust error management to catch unexpected runtime exceptions gracefully.
