"Symbol and definition lookup is another great feature of WebStorm. While Emacs can find symbols and definitions in a single file via Tern, ..."

Actually, tern has tern-find-definition which works not only in a single file. You can jump in to other modules in your project or to node_modules. And there is tern-pop-find-definition to return back. For methods of native js objects tern even opens browser with related MDN page. But WebStorm way better in debugging, that's true.

It's also worth noting that there's a lot of work going into Emacs right now to give it better IDE-like features -- finding definitions reliably, refactoring, all that stuff. They're working on a more generalized framework for supporting this stuff, and I'd expect Emacs to get significantly more competitive (with traditional IDEs) within the next year or two.

I haven't been able to make this work outside my current file. Perhaps I'm just configuring tern wrong :(

[ibabanov]

This .tern-project config works for me:

  {
    "libs": [
      "browser"
    ],
    "plugins": {
      "node": {},
      "es_modules": {}
    }
  }

Your project files must have "correct" format, e.g. require('relative_path') for imports and module.exports/exports for exports (or es6 import and export). Example for AMD format (requireJS) can be found here - http://ternjs.net/doc/manual.html#configuration

I can't get it to search outside the standard node files using the above config. I can't get it to be aware of my code in the project.
