title: Is there a linter for non-Dart polymer projects?
body: <p>I'm writing a prototype application using Polymer and native js (no Dart). I use VIM as my main editor and I'd like to incorporate a linter that will report A) when a referenced import does not exist or B) when a custom element is not defined anywhere.</p>
  
  <p>Is there a way to use the Dart linter from commandline on non-dart projects?</p>
