What is nodejs-argo?

This is a Node.js package that deploys a network proxy node on PaaS hosting platforms and similar lightweight server environments. It works by setting up an Argo tunnel, a technology from Cloudflare that routes traffic through their network to give you a stable public address without needing to open firewall ports yourself. The tool supports several proxy protocols, including VLESS, VMess, and Trojan, which are common formats used for encrypted traffic forwarding. To get it running, you install it through the standard Node.js package manager (npm) either globally or per-project, then configure it through environment variables. The README lists around fifteen configuration options, covering the listening port, your unique user ID, Argo tunnel credentials, the preferred outbound IP or domain, and optional integration with a monitoring tool called Nezha that tracks whether your service is still alive. If you do not provide Argo tunnel credentials, the tool falls back to a temporary tunnel that works without a fixed domain. The README includes instructions for running the server in the background using several common approaches: screen sessions, tmux, the PM2 process manager, and as a Linux system service via systemd. There is also a short code example showing how to load the package as a Node.js module if you want to start it programmatically from your own script. The project is written in Chinese and targets users who want to run a personal proxy node on free or low-cost cloud platforms. The README explicitly restricts commercial use and asks users to follow local laws regarding proxy services.
