Differential Polymer Demo

AS SEEN ON THE YOUTUBES

Installation

1. Clone the repository git clone https://github.com/Differential/polymer-demo
2. From the root directory of the meteor app, run bower install

• This will install Polymer, web components, & vulcanize
• Also, includes some custom elements we made so you can see how that works

3. Start the Meteor server meteor
4. WEB COMPONENTS!

Important concepts:

Including webcomponents.js

In the client/templates/layout/head.html file, there is a line that looks like this:

<script src="/components/webcomponentsjs/webcomponents.js"></script>

This is very important because it includes the web components polyfill.

imports.html

• This is where you list what Polymer components you want to load, from polymer core, paper-elements, and even your own custom components. We put these tags in a specific file client/templates/layout/imports.html which is then compiled with Vulcanize and the differential-vulcanize package to concatenate the web components into one file.

• After running bower install, your components will placed into the public/components directory, which you can see in the .bowerrc file

• There are customized polymer overrides in the client/stylesheets/components folder

Deploying to production

• Run your production deploy command with a VULCANIZE=true environment variable. i.e.. VULCANIZE=true modulus deploy
