README
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.
Download and install Node from https://nodejs.org/. Node includes the node package manager command,
npm
.Install
bower
andpolyserve
:npm install -g bower polyserve
Clone this repo:
https://github.com/googlecodelabs/polymer-first-elements.git
Change directory to your local repo and install dependencies with
bower
:cd polymer-first-elements bower install
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 usesicon-toggle
—the component name listed in this element'sbower.json
file—rather than the actual directory name.)
