We also use VS Code for debugging. It is a very easy debugging environment.

I use VS code for debugging because our stuff is generally platform agnostic. We also use winston for logging - so you can output debug logs when running in debug mode that don't clutter logs in prod mode.

Hi John,

Debugging Node.js can be done in a variety of fashions. Here's what I
currently do...

- REPL. The Node.js REPL is great for quickly testing smaller chunks
of code in PASE. I use this frequently to test my iterations of
formulating the correct parm lists for calling RPG programs.

- console.log(). Not ideal, but it works.

- If the code is platform agnostic then you can use the VSCode step
debugger (note this will eventually work for Node.js in PASE once IBM
addresses the node-inspector issue).

- Certain web frameworks have debug output capabilities while in
development mode. For example, ExpressJs debugging
