install node script on directadmin via remote access

I have a VPS that is managed through DirectAdmin and the only thing missing is a properly installed Node.js script. The code is ready on my local machine; what I need is someone to connect through the remote access I will provide, place the script on the server, install any required npm packages, and make sure the process keeps running (PM2 or an equivalent service manager is fine).

DirectAdmin is already set up, SSH access is enabled, and Node.js can be installed or upgraded if your checks show it is outdated. Once the script is live, please show me the basic start, stop, and log commands so I can manage it myself after you leave.

Deliverable:
• Script running in production mode and automatically restarting on reboot, with a brief text file noting the exact commands used.
