Breaking Changes

  • As announced previously, we're using ES Modules now! You'll need to convert your HTML Imports files to modules either manually, or using our modulizer tool.
  • With the ES Module change, a lot of API names have shortened now that they don't use the Polymer global. Here's an example:
    • Before:
      <link rel="import" href="polymer/lib/utils/case-map.html">
      import {CaseMap} from "@polymer/polymer/lib/utils/case-map.js";
  • However, Polymer.Element became PolymerElement, as Element would shadow over the native Element class.
  • importHref() functionality is removed, please use the ES Module equivalent: import('path/to/module.js' )
    • Polymer CLI tooling and Webpack will automatically fix this up for browsers that don't support ES Modules.
