Greeta Landing + Waitlist API

Stack

• React (Vite)
• Vercel Functions (/api/waitlist, /api/waitlist-count)
• Supabase (waitlist storage)
• Resend (confirmation email)

Required env vars

• SUPABASE_URL
• SUPABASE_ANON_KEY or SUPABASE_SERVICE_ROLE_KEY
• SUPABASE_WAITLIST_TABLE (optional, defaults to waitlist)
• RESEND_API_KEY (optional, enables confirmation emails)
• RESEND_FROM (optional, defaults to Greeta <onboarding@resend.dev>)
• TURNSTILE_SECRET_KEY (optional, enables Cloudflare Turnstile verification)
• VITE_TURNSTILE_SITE_KEY (optional, renders Turnstile widget in frontend)

Local development

• Frontend only: npm run dev
• API server (Vercel Functions on port 3000): npm run dev:api
• Frontend + Vercel in one server: npm run dev:vercel

If you run npm run dev on http://localhost:5173, it now proxies /api/* to http://localhost:3000. So run these in two terminals:

1. npm run dev:api
2. npm run dev
