# Next.js App Router Patterns ## Project Structure ``` app/ ├── (auth)/ # Route Group │ ├── login/page.tsx │ ├── register/page.tsx │ └── layout.tsx ├── (dashboard)/ │ ├── layout.tsx │ ├── page.tsx │ └── [projectId]/ │ └── page.tsx ├── api/ │ └── webhooks/route.ts ├── layout.tsx ├── page.tsx ├── loading.tsx ├── error.tsx └── not-found.tsx ``` ## Server vs Client Components ### Decision Tree - Need interactivity (onClick, useState)? -> 'use client' - Need browser APIs? -> 'use client' - Otherwise -> Server Component (default) ### Server Component ```tsx // No directive needed - Server Component by default import { prisma } from '@/lib/db' export default async function UsersPage() { const users = await prisma.user.findMany() return <UserList users={users} /> } ``` ### Client Component ```tsx 'use client' import { useState } from 'react' export function Counter() { const [count, setCount] = useState(0) return <button onClick={() => setCount(c => c + 1)}>{count}</button> } ``` ## Server Actions ```tsx // lib/actions/users.ts 'use server' import { revalidatePath } from 'next/cache' import { redirect } from 'next/navigation' export async function createUser(formData: FormData) { const email = formData.get('email') as string await prisma.user.create({ data: { email } }) revalidatePath('/users') redirect('/users') } ``` ### Using in Forms ```tsx import { createUser } from '@/lib/actions/users' export function
