title: About using TypeScript on AWS NodeJS. (getting stacktrace of TS instead of JS one)
body: <p>I am considering to convert my current js codebase to use TypeScript in NodeJS.</p>
  
  <p>One thing that concern me is that if error occurs on a request, I can see the stacktrace in AWS CloudWatch (request log) to understand the exact code line that cause the problem.</p>
  
  <p>If I use typescript, I suppose the log can still point me to the crash line from the transpiled js file. But I wonder if its possible to give me callstack to the ts file instead, which is more natural to me as I wrote ts instead of the js file.</p>
  
  <p>Thanks</p>
