Production Applications with PM2
summary
PM2 is a production process manager for Node.js that claims 2 million downloads and ~10,000 GitHub stars, and ships a built‑in load balancer, cluster mode to use all CPUs, zero-downtime reloads and a simple deployment workflow driven by an ecosystem.json. It includes a module system (examples: pm2-logrotate, pm2-webshell) and integrates with keymetrics.io for monitoring. The project reports ~2,500 commits, 120 contributors and 750 tests; Docker works but requires foreground mode care and extra documentation.
