Vaadin Groovy Builder (Vaadin Groovy Extensions)

This is a Groovy extensions and DSL library for the Vaadin framework.

This library:

Allows you to create Vaadin UI designs/component graphs in the structured code way; the idea behind is explained in the DSLs: Explained for Vaadin 8 article / DSLs: Explained for Vaadin 10 article. The general DSL idea is explained in Kotlin Type-Safe Builders.
Additional useful methods which Vaadin lacks

The full documentation:

Unfortunately there is no support for Vaadin 8 and lower
Vaadin-Groovy-Builder Vaadin Platform (Vaadin 14+) tutorial

Note: For Kotlin Vaadin DSL please see the Karibu-DSL library.

Example Project

See Vaadin Groovy Builder Example. Code example:

@Route("")
@CompileStatic
class MainView extends GComposite {
    private TextField name
    private Button sayHello
    private def root = ui {
        verticalLayout {
            name = textField("Your name") {}
            sayHello = button("Say hello") {}
        }
    }
    MainView() {
        sayHello.addClickListener {
            Notification.show("Hello, ${name.value}")
        }
    }
}

There is also an embedded example project attached to this repository. This allows us to test new builder features right away. Please see the example project for more details.
