Development tools?

Can you please share a bit more info, how to do that?
1.0.) Visual Studio 2017 is running on my Win7 laptop
1.1.) Installed Node.js development tool
1.2) Have a local copy of the code of all files.

2.) Node-RED is running on the Raspberryi Pi (debian latest, no desktop, openhabian based)

What's next? How do I remote-debug?
