Polymer Snippets

Small, useful, snippets/samples that show how to do things the Polymer way.

Port of polymer.js snippets in

Repo structure

All snippets go in web/.

Each snippet should have its own directory. Here is a typical list of files for a snippet:

  • my_element.html: the HTML for <my_element>
  • my_element.dart: the Dart code for <my_element>
  • index.html: the entry point for the snippet. Imports <my-element>.
  • the documentation for the snippet. This should mirror the documentation in the original as much as possible.

Unless there is a compelling reason to do so, name your element <my_element>.

Be sure to add the snippet to the entry_points list in pubspec.yaml.

Keeping track of upstream commits

When porting a polymer.js snippet, be sure to reference the original, and include the commit ID. For example:


See for details on how to get a link to the commit ID.

Making your snippets Dart-y

All snippets should follow the Dart Style Guide.

Before creating a pull request, please run the sample in Dart Editor, ensuring that it runs in both JS and Dartium without errors or warnings.
