Next.js App Router projects should use server components by default to render data-heavy or SEO-critical UI without extra client-side JavaScript, isolating interactive widgets as client islands using minimal boundaries.

You should add 'use client' only to leaf components that require interactivity, establishing minimal client boundaries. This prevents unnecessary JavaScript on data-heavy pages while preserving server-side rendering performance.

The best way to isolate interactive widgets is applying server-first patterns across pages and routing, adding 'use client' strictly to interactive leaf components to maintain performance and maintainability.

Yes, this approach applies server-first patterns to dashboards, lists, and content pages. It enforces structured design system conventions and documented guidelines to ensure performance across all typical page types.

Data fetching and routing conventions are managed through App Router patterns across components, hooks, and pages, emphasizing server components by default to improve performance and maintainability.

Using server components by default improves performance by rendering data-heavy or SEO-critical UI without extra client-side JavaScript, reducing bundle size while enforcing structured design conventions for maintainability.
