How to proper debug custom node

This is how I debug a custom node in VS Code... It works for me however since this is a dist version of node-red its difficult sometimes to debug client side issues.

And although the topic is about debuging a custom node - it works perfectly well for your requirement...

Just put debugger in your function node

e.g...

var x = msg.payload;
debugger
//...some complex code
//...some complex code
//...some complex code
//...some complex code
return msg;

and if its all working, VSCode will pause on the debugger line.
