Use when building Next.js applications, implementing SSR/SSG, or optimizing React Server Components.</h2>\n<h1>Next.js App Router Patterns</h1>\n<p>Comprehensive patterns for Next.js 14+ App Router architecture, Server Components, and modern full-stack React development.</p>\n<h2>When to Use This Skill</h2>\n<ul>\n<li>Building new Next.js applications with App Router</li>\n<li>Migrating from Pages Router to App Router</li>\n<li>Implementing Server Components and streaming</li>\n<li>Setting up parallel and intercepting routes</li>\n<li>Optimizing data fetching and caching</li>\n<li>Building full-stack features with Server Actions</li>\n</ul>\n<h2>Core Concepts</h2>\n<h3>1. Rendering Modes</h3>\n<table>\n<thead>\n<tr>\n<th>Mode</th>\n<th>Where</th>\n<th>When to Use</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><strong>Server Components</strong></td>\n<td>Server only</td>\n<td>Data fetching, heavy computation, secrets</td>\n</tr>\n<tr>\n<td><strong>Client Components</strong></td>\n<td>Browser</td>\n<td>Interactivity, hooks, browser APIs</td>\n</tr>\n<tr>\n<td><strong>Static</strong></td>\n<td>Build time</td>\n<td>Content that rarely changes</td>\n</tr>\n<tr>\n<td><strong>Dynamic</strong></td>\n<td>Request time</td>\n<td>Personalized or real-time data</td>\n</tr>\n<tr>\n<td><strong>Streaming</strong></td>\n<td>Progressive</td>\n<td>Large pages, slow data sources</td>\n</tr>\n</tbody>\n</table>\n<h3>2. File Conventions</h3>\n<pre><code>app/\n├── layout.tsx       # Shared UI wrapper\n├── page.tsx         # Route UI\n├── loading.tsx      # Loading UI (Suspense)\n├── error.tsx        # Error boundary\n├── not-found.tsx    # 404 UI\n├── route.ts         # API endpoint\n├── template.tsx     # Re-mounted layout\n├── default.tsx      # Parallel route fallback\n└── opengraph-image.tsx  # OG image generation\n</code></pre>\n<h2>Quick Start</h2>\n<pre><code>// app/layout.tsx\nimport { Inter } from 'next/font/google'\nimport { Providers } from './providers'\n\nconst inter = Inter({ subsets: ['latin'] })\n\nexport const metadata = {\n  title: { default: 'My App', template: '%s | My App' },\n  description: 'Built with Next.js App Router',\n}\n\nexport default function RootLayout({\n  children,\n}: {\n  children: React.ReactNode\n}) {\n  return (\n    &lt;html lang=\"en\" suppressHydrationWarning&gt;\n      &lt;body className={inter.className}&gt;\n        &lt;Providers&gt;{children}&lt;/Providers&gt;\n      &lt;/body&gt;\n    &lt;/html&gt;\n  )\n}\n\n// app/page.tsx - Server Component by default\nasync function getProducts() {\n  const res = await fetch('https://api.example.com/products', {\n    next: { revalidate: 3600 }, // ISR: revalidate every hour\n  })\n  return res.json()\n}\n\nexport default async function HomePage() {\n  const products = await getProducts()\n\n  return (\n    &lt;main&gt;\n      &lt;h1&gt;Products&lt;/h1&gt;\n      &lt;ProductGrid products={products} /&gt;\n    &lt;/main&gt;\n  )\n}\n</code></pre>\n<h2>Detailed patterns and worked examples</h2>\n<p>Detailed pattern documentation lives in <code>references/details.md</code>. Read that file when the navigation tier above is insufficient.</p>\n<h2>Best Practices</h2>\n<h3>Do's</h3>\n<ul>\n<li><strong>Start with Server Components</strong> - Add 'use client' only when needed</li>\n<li><strong>Colocate data fetching</strong> - Fetch data where it's used</li>\n<li><strong>Use Suspense boundaries</strong> - Enable streaming for slow data</li>\n<li><strong>Leverage parallel routes</strong> - Independent loading states</li>\n<li><strong>Use Server Actions</strong> - For mutations with progressive enhancement</li>\n</ul>\n<h3>Don'ts</h3>\n<ul>\n<li><strong>Don't pass serializable data</strong> - Server → Client boundary limitations</li>\n<li><strong>Don't use hooks in Server Components</strong> - No useState, useEffect</li>\n<li><strong>Don't fetch in Client Components</strong> - Use Server Components or React Query</li>\n<li><strong>Don't over-nest layouts</strong> - Each layout adds to the component tree</li>\n<li><strong>Don't ignore loading states</strong> - Always provide loading.tsx or Suspense</li>\n</ul>\n","files":[{"path":"references/details.md","sizeBytes":9939,"isText":true},{"path":"SKILL.md","sizeBytes":3714,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
