VPS production deploy

Environment variables

Set these on your VPS (same values for both URLs in production):

NODE_ENV=production
PORT=3000
DATABASE_URL=postgresql://user:pass@host:5432/personal_epistemology
SESSION_SECRET=<long-random-string>
GOOGLE_CLIENT_ID=...
GOOGLE_CLIENT_SECRET=...
DEEPSEEK_API_KEY=...
APP_URL=https://your-domain.com
CLIENT_URL=https://your-domain.com
COOKIE_SECURE=true

COOKIE_SECURE=true is required when running behind nginx/HTTPS reverse proxy.

Google OAuth production redirect URI:

https://your-domain.com/api/auth/google/callback

Option A: Nixpacks (Railway, Coolify, etc.)

The included nixpacks.toml will:

1. Install dependencies
2. Generate Prisma client + build client & server
3. Run migrations on start
4. Serve everything on one port

Option B: Manual VPS deploy

npm install
npm run build
npm run db:migrate:deploy
NODE_ENV=production npm start

Or use deploy/start.sh.

Nginx reverse proxy

See deploy/nginx.conf — proxy all traffic to port 3000. The Node server serves both the API and the React SPA.

Health check

GET /api/health

Returns { ok: true, db: "connected" } when healthy.
