nextjs-best-practices

To choose between Server and Client Components in Next.js App Router, evaluate whether the component requires interactivity or direct browser APIs. Server Components fetch data securely on the server, while Client Components handle state and user events.

The best way to fetch data in Next.js is by utilizing Server Components to fetch directly on the server. This approach leverages built-in caching strategies and reduces client-side bundle sizes, improving overall application performance.

To optimize images and bundle sizes in Next.js, follow performance best practices specific to the App Router. This involves using built-in image optimization components and properly splitting code between Server and Client Components.

You should use Server Actions in Next.js when you need to handle form submissions or mutate data directly on the server without creating separate API routes. They streamline data mutations and maintain type safety across the stack.

Common Next.js App Router anti-patterns include unnecessary usage of Client Components, improper data fetching strategies, and ignoring caching principles. Avoiding these ensures your application remains efficient, scalable, and maintainable.
