What You Get

File Conventions

app/
├── layout.tsx          # Root layout (wraps all pages)
├── middleware.ts        # Runs before route matching
├── page.tsx            # Route: /
├── about/
│   └── page.tsx        # Route: /about
├── blog/
│   ├── page.tsx        # Route: /blog

└── api/
    └── hello/
        └── route.ts    # API: /api/hello (GET/POST/etc)

• page.tsx — Page component (default export)
• layout.tsx — Wrapping layout (receives children)
• route.ts — API route (exports named HTTP method handlers: GET, POST, etc.)
• middleware.ts — Runs before routing; return Response to short-circuit, undefined to continue
• [param] — Dynamic segments (extracted as params.param)

Vite Plugin

// vite.config.ts
import { defineConfig } from 'vite'

export const metadata = { title: 'Home', description: 'Welcome' }

export default function Home() {
  return <h1>Hello, World!</h1>

export async function GET(request: Request) {
  return new Response(JSON.stringify({ message: 'hello' }), {
    headers: { 'Content-Type': 'application/json' },
  })
}

export async function POST(request: Request, { params }: { params: Record<string, string> }) {
  const body = await request.json()
  return new Response(JSON.stringify({ received: body }))
}

Middleware

// app/middleware.ts
export default function middleware(request: Request) {
  if (!request.headers.get('Authorization')) {
    return new Response('Unauthorized', { status: 401 })
