Your first Polymer element

This repo goes with the Build your first Polymer element codelab.

The codelab is designed to be used with Chrome Dev Editor. See the next section if you'd like to use another editor for the codelab.

Running the codelab without Chrome Dev Editor

If you're not using CDE, you'll need to install some command-line tools to manage dependencies and to run the demo.

  1. Download and install Node from https://nodejs.org/. Node includes the node package manager command, npm.

  2. Install bower and polyserve:

    npm install -g bower polyserve
    
  3. Clone this repo:

    https://github.com/googlecodelabs/polymer-first-elements.git
    
  4. Change directory to your local repo and install dependencies with bower:

    cd polymer-first-elements
    bower install
    
  5. To preview your element, run polyserve from the repo directory:

    polyserve
    

    Open localhost:8080/components/icon-toggle/demo/ in your browser. (Note that the path uses icon-toggle—the component name listed in this element's bower.json file—rather than the actual directory name.)

If you're wondering what polyserve does, see Testing elements with local bower dependencies in the Polymer docs.
