title: How to see full search path for ES 6 import libraries
body: <p>I'm reading the code of a node application, and at the top of a file, I see an ES6-style import statement like</p>
  
  <pre><code>import Foobar from "foobar"
  </code></pre>
  
  <p>But I'm not sure where this <code>foobar</code> library is coming from.  There's not file called "foobar.js" in the project and there's not "foobar" library stated in the <code>package.json</code>.  Is it possible to see a comprehensive list of paths that the <code>import</code> directive searches?</p>
