Next.js 16 App Router audits verify that pages and layouts default to Server Components, pushing 'use client' to interactive leaves and separating data fetching from client code to prevent hydration and performance regressions.

Configuring cache components in Next.js 16 involves using the opt-in cache components API and applying explicit cache invalidation strategies. This ensures data fetching across server and client boundaries remains fresh without causing routing regressions.

Migrating from middleware to proxy.ts routing in Next.js requires moving request interception logic into the proxy.ts file. This standardizes routing configurations and aligns with Next.js 16 App Router best practices for request handling.

Next.js 16 works with React Compiler and Turbopack to optimize performance. Configuring these tools alongside Suspense streaming and query-layer separation ensures applications maintain fast load times and strict TypeScript typing for API handlers.

Using Server Components by default in Next.js reduces client-side JavaScript overhead and improves performance. Client Components should only be used at interactive leaves, keeping data fetching on the server to leverage streaming and caching standards.
