Yeoman generator for Polymer projects


Polymer is a library of polyfills and sugar which enable the use of Web Components in modern browsers. The project allows developers to build apps using the platform of tomorrow and inform the W3C of places where in-flight specifications can be further improved.

generator-polymer-cordova provides Polymer scaffolding using Yeoman (a scaffolding tool for the web), letting you easily create and customize Polymer (custom) elements via the command-line and import them using HTML Imports. This saves you time writing boilerplate code so you can start writing up the logic to your components straight away.


  • A Polymer app scaffold based in Polymer Starter Kit but modified in order to add cordova support.
  • Sub-generator to create Polymer elements for your app
  • Quick deploy to GitHub pages
  • All the goodness of seed-element (docs & landing page for your element)
  • web-component-tester support


This generator clones Polymer Starter Kit and seed-element. If you're having issues with the template files generated for those projects, please raise them on those repos as they are the canonical source.


Install the generator npm install -g generator-polymer-cordova

Make a new directory and cd into it mkdir -p my-project && cd $_

Scaffold a new Polymer project: yo polymer-cordova


Available generators:

Note: Generators are to be run from the root of your app


Sets up a new Polymer app, generating all the boilerplate you need to get started.


yo polymer-cordova

Element (alias: El)

Generates a polymer element in app/elements and optionally appends an import to app/elements/elements.html.


yo polymer-cordova:element my-element

# or use the alias

yo polymer-cordova:el my-element

Note: You must pass in an element name, and the name must contain a dash "-"

One can also include element dependencies to be imported. For instance, if you're creating a fancy-menu element which needs to import paper-button and paper-checkbox as dependencies, you can generate the file like so:

yo polymer-cordova:el fancy-menu paper-button paper-checkbox


--docs, include iron-component-page docs with your element and demo.html
--path, override default directory structure, ex: --path foo/bar will put your element in app/elements/foo/bar


Generates a reusable polymer element based on the seed-element workflow. This should only be used if you're creating a standalone element repo that you intend to share with others via bower. If you're just building a Polymer app, stick to the Element generator.

To preview your new element you'll want to use the polyserve tool.


mkdir -p my-foo && cd $_
yo polymer-cordova:seed my-foo


Generates a Github pages branch for your seed-element.

This requires that you have SSH keys setup on GitHub.

If your documentation or demo pages have dependencies declared as devDependencies in bower.json, they will be included in your GitHub pages branch.


cd my-foo
yo polymer:gh

If, for some reason, you don't want the devDependencies, use the --nodevdeps option.


The project generated by yo polymer contains support for web-component-tester. The following commands are included:

Run local tests (in terminal):

gulp test:local

Run remote tests with SauceLabs:

gulp test:remote

See the web-component-tester readme for configuration options.


The elements.html file

The app generator will produce an elements.html file where you can place your imports. This file will be vulcanized when you run the default gulp task. You'll want to make sure that elements.html is the only import in your index.html file, otherwise there's a good chance you'll accidentally load Polymer twice and break the app.


See the contributing docs

When submitting an issue, please follow the guidelines. Especially important is to make sure Yeoman is up-to-date, and providing the command or commands that cause the issue.
