title: How to add JS source map into Chrome devtools?
body: <p>My deployed JavaScript application raises an exception. The Javascript code is obfuscated. I would like to know, which line in original source code raises an exception. Source maps are not deployed, so Chrome Devtools can't connect them. I may have source maps on my localhost.</p>
  
  <p>So basically I would like to add source maps from my machine to the browser in order to know the line number, where exceptions occurs. </p>
  
  <p>I tried <code>Add Folder to Workspace</code> and <code>Map to File System Resource</code>. It does not help. An exception is visible in browser's console, but it still points into obfuscated javascript source and desired line number is not detectable.</p>
  
  <p>I may do something wrong. Any help is appreciated (including additional extension or other browser usage).</p>
