This is a Payment Request API demo app built with Vaadin components and Polymer.
For more resources about Payment Request API I suggest to check out Google Developer's Deep Dive into the Payment Request API guide.
Ensure npm, bower and polymer-cli are installed

$ polymer serve
This command builds your Polymer application for production and generates service worker, using build configuration options provided by the command line or in your project's polymer.json file.
You can configure your polymer.json file to create multiple builds. You can define your own named builds, or use presets. See the Polymer's documentation on building your project for production for more information.
$ polymer build
