The Vaadin components are distributed as Bower and npm packages. Please note that the version range is the same, as the API has not changed. You should not mix Bower and npm versions in the same application, though.
Unlike the official Polymer Elements, the converted Polymer 3 compatible Vaadin components are only published on npm, not pushed to GitHub repositories.
