Supabase

Supabase is the store for Proj.Help: Postgres rows (ideas, replies) plus Auth (GitHub or Microsoft). File buckets are not required for the current hub.

The Marketplace integration on Vercel only copies keys into environment variables. You still run SQL and configure OAuth in Supabase Studio.

After connecting on Vercel

1. Confirm env vars — Vercel deploys
2. Redeploy so NEXT_PUBLIC_ keys are in the build
3. Vercel project → Storage → Supabase → Open in Supabase
4. SQL Editor (not Vercel Query). Run each file in full, in order:
   • supabase/migrations/20260904112922_init_proj_help.sql
   • supabase/migrations/20260904140000_allow_github_auth.sql
     Those paths are in Tiger-Studio-Website, not this docs repo.
5. Authentication → URL configuration
   • Site URL: https://tiger-studio-website.vercel.app
   • Redirect URLs (keep ** so query strings and previews match):
     • https://tiger-studio-website.vercel.app/auth/callback**
     • http://localhost:3000/auth/callback**
6. Authentication → Providers
   • Disable Email
   • Enable GitHub (below)
   • Keep Azure only if an Entra app exists

GitHub OAuth for Join

If GitHub sign-in “doesn’t finish”, the Authorization callback URL is usually wrong.

1. GitHub → Settings → Developer settings → OAuth Apps → New OAuth App

2. Homepage URL: https://tiger-studio-website.vercel.app

3. Authorization callback URL must be , not Vercel:
