description	Master Next.js 16+ App Router with Server Components, streaming, parallel routes, and advanced data fetching. Use when building Next.js applications, implementing SSR/SSG, or optimizing React Server Components.

Next.js App Router Patterns

Comprehensive patterns for Next.js 16+ App Router architecture, Server Components, and modern full-stack React development.

[!CAUTION] Project Europa 制約: このプロジェクトは output: 'export' (静的エクスポート) を使用しているため、以下の機能は使用不可です:

• Server Components (RSC)
• Server Actions ('use server')
• Streaming / Suspense boundaries
• Route Handlers (API Routes)
• ISR / Cache tags

代替: TanStack Query でクライアントサイドデータ取得、Hono バックエンド (/api/v2/) を使用してください。

Use this skill when

• Building new Next.js applications with App Router (v16+)
• Migrating from Pages Router to App Router
• Implementing Server Components and streaming
• Setting up parallel and intercepting routes
• Optimizing data fetching and caching
• Building full-stack features with Server Actions

Do not use this skill when

• The task is unrelated to next.js app router patterns
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.
