Comprehensive patterns for Next.js 14+ App Router architecture, Server Components, and modern full-stack React development.
## When to Use This Skill
- Building new Next.js applications with App Router
- 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
## Core Concepts
### 1. Rendering Modes
| Mode | Where | When to Use |
| --------------------- | ------------ | ----------------------------------------- |
| **Server Components** | Server only | Data fetching, heavy computation, secrets |
| **Client Components** | Browser | Interactivity, hooks, browser APIs |
| **Static** | Build time | Content that rarely changes |
| **Dynamic** | Request time | Personalized or real-time data |
| **Streaming** | Progressive | Large pages, slow data sources |

```typescript
// app/layout.tsx
import { Inter } from 'next/font/google'
import { Providers } from './providers'
const inter = Inter({ subsets: ['latin'] })
export const metadata = {
title: { default: 'My App', template: '%s | My App' },
description: 'Built with Next.js App Router',
}
export default function RootLayout({

children: React.ReactNode
}) {
