How does Nginx work as a reverse proxy for DevTinder?
Nginx listens on port 80 (and 443 with SSL) and proxies requests to the Node.js app on port 3000. It handles SSL termination, static file serving, and WebSocket upgrades for Socket.io. The Upgrade and Connection headers are critical for WebSocket support.

Launch an Ubuntu EC2 instance, install Node.js and PM2, clone the backend repo, configure .env, start with pm2 start, configure Nginx as a reverse proxy, and add SSL with Let's Encrypt. The frontend can be deployed to Vercel separately.
PM2 keeps the Node.js process running, automatically restarts on crash, starts on system boot with pm2 startup, and provides log management. Without PM2, the app would stop when the SSH session ends or on an unhandled error.
Install certbot and the Nginx plugin (sudo apt install certbot python3-certbot-nginx), then run sudo certbot --nginx -d yourdomain.com. Certbot automatically configures Nginx for HTTPS and sets up auto-renewal.
