How to Remotely Debug a Node.js Process

• Open the Brave/Chrome dev tools - brave://inspect/#devices
• Click on Open dedicated DevTools for Node
• Log in to the remote host:

ssh USER@REMOTE_IP

• Figure out how to add --inspect-brk to the startup for your app
• Bounce the app with whatever process manager you use
