SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enforces correct, modern Next.js 16 App Router usage across projects, preventing common pitfalls when building pages, layouts, routing, and data fetching.

FAQPage Schema
How do I enforce Server Components as the default in Next.js 16 App Router?▼

To decide between Server and Client Components in Next.js 16, use Server Components for data fetching and static rendering. Add the "use client" directive only for UI interactivity, state, or browser API access.

How do I manage authentication boundaries and tokens in Next.js 16?▼

Manage authentication boundaries in Next.js 16 by confining token handling strictly to server context. Use Server Components, Route Handlers, or Server Actions to prevent sensitive tokens from leaking into Client Components.

Does Next.js 16 App Router support file-system routing for layouts and pages?▼

Next.js 16 App Router supports file-system routing to define pages and layouts. This mechanism enforces strict routing rules and hierarchical UI structures based on the file organization within the app/ directory.
