Use server components by default for data fetching and static content in Next.js App Router, and switch to client components only when user interactivity is required. This separation optimizes performance and user experience.

Organize routing and data fetching in Next.js 13+ by applying recommended patterns for layout and route organization. Structure your architecture around server-side data fetching, caching, and ISR to ensure scalable apps.

The best way to start refactoring with Next.js App Router is auditing your app for server versus client components. Apply the default server component rule, then document your routing structure and data-fetching patterns.

This guidance applies to projects using Next.js 13+ with App Router across routes, layouts, and data fetching scenarios. It suits both new projects and refactoring existing apps for consistent architecture.

Separating server and client concerns reduces ambiguity around data fetching strategies and routing patterns. It enforces clear component boundaries, resulting in more maintainable and scalable Next.js applications.
