How to debug aws lambda functions written in node js

Question

We have been developing AWS Lambda functions in Node JS for a few months. Can we debug, i.e. step through the Node JS code as we can with .Net C# code in Visual Studio?

Answer 1

Trek 10 released an interesting tool recently that allows stepping through node.js code live in AWS lambda functions! How, you may ask? "Magic and mirrors", according to them :-)

Apparently, it doesn't attach to Amazon's host process directly (which is impossible), but it forks your code into a child process running in debug mode and proxies connections to your local Chrome DevTools. (There is actually a little more to the configuration, which you can read about at the github repo below.)
