Polymer 2 Element Template Webstorm/IntelliJ (Bare Minimum)

element-template.tmpl.html

<link rel="import" href="../bower_components/polymer/polymer-element.html">
<link rel="import" href="shared-styles.html">

<dom-module id="$NAME">
  <template>
    <style include="shared-styles">
      :host {
        display: block;
      }
    </style>

  </template>

  <script>
    class $ElementName extends Polymer.Element {
      static get is() { return '$NAME'; }
    }

    window.customElements.define(($ElementName).is, $ElementName);
  </script>
</dom-module>

This should work if the element is placed in a folder that is a sibling to the bower_components directory (e.g. /src/)
