🔧 API Route Format:
- Add /api/simple.js using standard Vercel function format
- Add /api/hello.ts using proper Next.js API route format
- Install Next.js and types for proper API route support
🧪 Testing Multiple Formats:
- JavaScript endpoint: /api/simple.js
- TypeScript endpoint: /api/hello.ts
- Both use traditional req/res pattern instead of NextRequest/NextResponse
This should help identify the correct API format for Vercel functions.
