Use Neon when you want a managed Postgres database for Launch.

​
Create a Neon database

  1. Create a project in Neon.
  2. Copy the connection string from the Neon dashboard.
  3. Set it as DATABASE_URL in apps/api/.env:
DATABASE_URL=postgresql://user:[email protected]/db

​
Apply migrations

After setting DATABASE_URL, run the same migration commands you use locally: 
pnpm --filter api db:generate
pnpm --filter api db:migrate
pnpm --filter api db:push

​
Run migrations safely

Be careful running migrations against production from your laptop. Recommended safety practices:
  • Run migrations from CI (GitHub Actions) instead of local machines.
  • Apply migrations only after a successful deploy.
  • Use a dedicated “migration” step with environment‑scoped credentials.
  • Test migrations on a staging database first.
If you need more control, move to a CI workflow that runs migrations with explicit approvals and environment protection rules.
