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.

Polymer 2 and HTML Imports compatible version

Install vaadin-charts:

bower i vaadin/vaadin-charts --save

Once installed, import it in your application:

<link rel="import" href="bower_components/vaadin-charts/vaadin-chart.html">

Polymer 3 and ES Modules compatible version

Install vaadin-charts:

npm i @vaadin/vaadin-charts --save

Once installed, import it in your application:

import '@vaadin/vaadin-charts/vaadin-chart.js';

Install License Key

After one day using Vaadin Charts in a development environment you will see a pop-up that asks you to enter the license key. You can get your trial key from If the license is valid, it will be saved to the local storage of the browser and you will not see the pop-up again.
