Описание тега vaadin
Vaadin is an open source client-server framework, that builds on GWT (Google Web Toolkit) or Web components using Polymer. It uses pure Java for the server-side UI code and depending on version either Java or JavaScript for client-side code. Vaadin improves the client side presentation layer by introducing client-server web components for rapid application development. From Vaadin 15 onwards it is possible to compose client side views also with TypeScript.
Until Vaadin 8, the client-side is based on GWT and starting from Vaadin 10 Polymer 2.0 and from Vaadin 14 Polymer 3.0 is used instead for the client side.
