To structure scalable Next.js App Router applications, adopt file-based routing conventions like layout.tsx and page.tsx, incrementally replacing ad-hoc routing with server components, server actions, and route handlers to enforce guardrails against anti-patterns.

Use server components versus client components in Next.js based on concrete guidelines: default to server components for data fetching and backends, using client components only when necessary, avoiding common anti-patterns for robust application architecture.

Configure SEO metadata and Open Graph in Next.js by using the Metadata API, which supports dynamic metadata generation across your project to ensure proper search engine optimization and social sharing configuration.

The best way to handle data fetching in Next.js is by leveraging server components, server actions, and route handlers, which provide robust backend patterns and performance considerations like suspense and lazy loading for scalable applications.

The Next.js App Router approach supports dynamic routes, loading, error, and not-found file conventions natively, allowing you to build robust applications with built-in guardrails against common anti-patterns.
