🔧 Build Fixes:
- Update Node.js version from 18.x to 22.x (required by Vercel)
- Remove debug endpoints to get under 12 function limit for Hobby plan
- Downgrade React from 19.x to 18.x for better compatibility
- Update react-router-dom to v6.28.0 (compatible with Node 22)
- Update TypeScript to v5.7.3
- Update React types to match React version
Functions count: 12/12 (at limit for Hobby plan)
Core API endpoints:
✅ auth/login.js, auth/register.js
✅ collections/index.js, collections/add-card.js
✅ cards/find-or-create.js
✅ admin/users.js, admin/promote-user.js
✅ setup-auth.js, simple.js
✅ Legacy: migrate.ts, v1/cards/[id].ts, v1/cards/index.ts
🔧 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.
