ExpressJs — Load Balancing Express Apps

Distribute traffic across multiple Express app instances using a reverse proxy or load balancer like Nginx or PM2 to improve reliability and uptime.

# Example Nginx config
upstream express_cluster {
  server 127.0.0.1:3000;
  server 127.0.0.1:3001;
}

server {
  listen 80;
  location / {
    proxy_pass http://express_cluster;
  }
}
