Fix Next.js App Router server-client component boundaries by validating serializable props, correctly using server actions, and ensuring client components isolate interactive logic to prevent hydration bugs.

Async request APIs in Next.js server components require proper serialization rules and runtime selection to fetch data reliably without blocking the render cycle or causing deployment failures.

Validate Next.js file conventions by checking route segments, parallel routes, and intercepting routes against special files like layout, loading, error, and not-found to ensure correct architectural structure.

Optimize Next.js images, fonts, and scripts by applying production-safe patterns for bundling, Suspense boundaries, and metadata handling to improve performance and SEO reliably before deployment.

Next.js best practices guidance applies to self-hosting workflows by validating route handlers, error handling, and runtime selection to ensure robust production deployments without relying on managed platforms.

Broken routing and poor performance in Next.js 16 applications stem from incorrect architecture, invalid async API usage, and missing Suspense boundaries, requiring validation of file conventions to resolve.
