pm2 Quick Start

I couldn't find a single consolidated place that explains how to setup pm2 from scratch (assuming you've already installed Node.js), and their own "quick start" didn't help. I was finally able to piece together how to get it working.

1. Install pm2: npm i -g pm2
2. Configure pm2 to restart processes on reboot: pm2 startup
3. If that command prints a command to run, run it.
4. cd to wherever your script is.
5. Run the script with pm2: pm2 start <command> -- <args>
   • pm2 start npm -- start
   • pm2 start node -- index.js
   • pm2 start npx -- tsx index.ts
6. Verify that it is running with pm2 list
7. Run pm2 save

Now if you reboot your system, pm2 should automatically start itself and the script you ran!
