Creating UI in Vaadin Applications
How to use components, create your own, or integrate 3rd party web components.
The Vaadin Design System includes a set of components that you can use to build your UI. The components have a server-side Java API in addition to the TypeScript API for client-side development.
You use a component by first creating it and then adding it to a containing layout.
For example, to add a Button component, create the object and add it to a layout.
Open in a
Button button = new Button("Click me!", event -> event.getSource().setText("Clicked!!!")); add(button);

- Integrating Web Components
- Element API
- You can control the HTML DOM in the browser from the server-side using the Element API.
