Progressive Web App with full offline capabilities
This is an example project for how you can build a Progressive Web Application with Polymer and Vaadin components.
The application uses a Service Worker to cache the Application Shell. A Web App Manifest file ensures that the browser identifies our app as a Progressive Web Application and offers the user to install the application through an install banner.

Docker container for production
You can use the included Dockerfile
to deploy the built app using prpl-server.
Build project locally
The default polymer.json
contains the "autoBasePath": true
setting to support differential serving with the prpl-server.
This option makes the build incompatible with static file servers, though. So, in order to serve bundled app locally using polymer-cli
, do the following steps:
-
Remove
"autoBasePath": true
setting from thepolymer.json
-
Run
polymer build
-
Run
polymer serve build/es6-bundled
(you can choosees5-bundled
instead)
Read more about the build options in the Polymer: Build for production documentation.
