As you may have noticed, we have migrated all of Vaadin's components to Polymer 3. This means that you can now install the components through NPM.
npm install @vaadin/vaadin-core
NPM is the standard package manager for front-end dependencies. The move will make it easier to use Vaadin components in frameworks like Angular or Vue. It also means that you are able to use build tools like Webpack without extra configuration.
This change only applies to developers using the WebComponent API. The Java API and component usage in Flow remains the same.
