Route Handlers are defined in route.ts files and export HTTP methods like GET, POST, PUT, PATCH, DELETE, and HEAD.

typescript

// app/api/users/route.ts
import { NextResponse } from 'next/server';

export async function GET() {
  const users = await db.user.findMany();
  return NextResponse.json(users);
}

export async function POST(request: Request) {
  const data = await request.json();
  const user = await db.user.create({ data });
  return NextResponse.json(user, { status: 201 });
}
