PM2 process manager: keep Node.js apps running on a VPS
Use PM2 to run Node.js apps in the background, restart them on crash, start them at boot, run cluster mode and manage logs with an ecosystem file.
Put a Node.js app behind Nginx, Apache or LiteSpeed (reverse proxy)
Serve a Node.js app on port 80/443 by proxying a domain to it with Nginx, Apache or OpenLiteSpeed, including headers, WebSocket support and testing.
