Next.js App Router best practices involve understanding file-based routing conventions and correctly managing React Server Component boundaries to separate server-side data fetching from client-side interactivity, avoiding common architectural pitfalls.

Data fetching in Next.js is handled optimally by leveraging React Server Components for direct database queries, utilizing Server Actions for mutations, and implementing Route Handlers for external API endpoints to ensure secure and efficient data patterns.

Next.js optimization is achieved by leveraging the built-in next/image and next/font modules, which automatically handle resizing, lazy loading, and font hosting to significantly improve application performance and Core Web Vitals.

Robust error handling in Next.js utilizes Error Boundaries and specific Next.js APIs to catch route errors gracefully, while the metadata API manages SEO tags directly within Server Components to improve maintainability and search visibility.

Yes, the Next.js best practices guide covers runtime selection between Node.js and Edge runtimes, alongside deployment considerations, ensuring your application architecture aligns with modern hosting environments for optimal performance.
