Next.js data fetching in Server Components should leverage async/await directly within the component to retrieve data before rendering, ensuring optimal performance by executing requests on the server and reducing client-side JavaScript bundles.

Choose Next.js Server Components for direct data fetching and rendering, Server Actions for form mutations and data modifications, and Route Handlers for standalone API endpoints processing HTTP requests like webhooks.

Next.js error management utilizes dedicated error.tsx boundaries to gracefully catch runtime exceptions, while metadata handling uses the exported Metadata API to dynamically generate SEO tags and HTML head elements per route.

Next.js automatically optimizes images and fonts through its built-in components, serving responsive formats like WebP and self-hosting fonts to prevent layout shifts and eliminate external network requests.

Common Next.js RSC boundary pitfalls include passing non-serializable data across boundaries and misusing client hooks in server components, which disrupts bundling strategies and breaks the intended server-side execution model.

Next.js requires strict file conventions like page.tsx for routing UI, layout.tsx for shared structure, and error.tsx for error handling, establishing maintainable application architecture and predictable rendering boundaries.
