Next.js App Router best practices for server and client boundaries involve standardizing file conventions, detecting serializable props, and structuring efficient data fetching to avoid waterfalls, ensuring scalable and reliable app architecture across projects.

To optimize Next.js images and fonts, apply performance optimization strategies covering image/font handling, bundling considerations, and self-hosting techniques to achieve production readiness and robust user experience.

Handling dynamic metadata and errors in Next.js route handlers requires applying specific data patterns for dynamic/static metadata, structuring error pages, and using API patterns to maintain robust UX during route execution.

This Next.js best practices guidance specifically applies to apps using the App Router, covering file conventions, middleware directives, and server/client boundaries, and does not target the older pages router architecture.

Standardizing Next.js routing patterns and middleware directives reduces ambiguity in app structure and route segments, guiding consistent and reliable development across teams while preventing common architectural pitfalls.
