Node.js and Python applications

Node.js and Python applications run as unprivileged, restartable systemd services on private localhost ports behind Nginx.

For Node.js websites, use Build and deploy to configure the package manager, install command, build command, start command, and protected environment variables. Deployment provides a repeatable alternative to entering these commands manually in a terminal. Environment variables are stored in a protected root-owned .env file and loaded by the managed service.

Node.js applications must listen on the injected HOST and PORT . Python starter applications use the system python3 and likewise receive private host and port settings. Nginx remains the public entry point.
