Server Components fetch data and render on the server, while Client Components handle interactivity. Use Server Components by default to optimize performance, only adding the client directive when you need state or browser APIs.

Next.js data fetching supports default caching, revalidation, and no-store patterns. Choose default for static content, revalidate for periodic updates, and no-store for dynamic data to control caching behavior.

Common Next.js anti-patterns include overusing Client Components, improper data fetching placement, and ignoring route-level caching. Avoid these pitfalls to ensure your web application maintains optimal performance and scalability.

Yes, Next.js Server Actions handle secure data mutations and form processing directly. They allow you to mutate data and revalidate the cache without creating separate API route handlers.

Next.js allows configuring both static and dynamic metadata for SEO. Generate dynamic metadata functions based on route parameters to automatically inject title and meta tags into your web application.

Optimize Next.js performance by using the built-in image component for lazy loading and responsive sizing. Bundle optimization relies on proper component splitting and managing server versus client boundaries.
