Yeoman generator for Polymer projects with ES2015 built in
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 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 built with Polymer Starter Kit
- 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
In addition, this generator leverages polymer-starter-kit-plus to provide ES2015 support "out of the box" along with many other bonus features!
See this README for more details.
- Element generator uses ES2015 classes
- Stylus support
- ReactiveElements using Rx lite and Rx DOM bindings
- Themes in
/themescan be styled using Stylus (CSS pre-processor)
- Suggestions are welcome ;)
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-plus
Make a new directory and cd into it
mkdir -p my-project && cd $_
Scaffold a new Polymer project:
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.
Element (alias: El)
Generates a polymer element in
app/elements and optionally appends an import to
yo polymer-plus:element my-element# or use the aliasyo polymer-plus: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-checkbox as dependencies, you can generate the file like so:
yo polymer-plus: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-plus:seed my-foopolyserve
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-fooyo polymer-plus:gh
If, for some reason, you don't want the devDependencies, use the
The project generated by
yo polymer contains support for web-component-tester. The following commands are included:
Run local tests (in terminal):
Run remote tests with SauceLabs:
See the web-component-tester readme for configuration options.
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.
