Karibu-DSL (Vaadin Kotlin Extensions)

This is a Kotlin extensions and DSL library for the Vaadin framework. Please visit Vaadin-on-Kotlin pages for the Getting Started guide.

This library:

  • Allows you to create Vaadin UI designs in the structured code way; the idea behind the library is explained in the DSLs: Explained for Vaadin article (or for older Vaadin 8: DSLs: Explained for Vaadin 8). The general DSL idea is explained in Kotlin Type-Safe Builders.
  • (Vaadin 8 only): Auto-discovery and auto-mapping of Views via a custom Navigator
  • Additional useful methods which Vaadin lacks

The documentation differs for Vaadin 14 and for older Vaadin 8:

The origins of the word Karibu: it's a term for North American subspecies of the reindeer; that connects to Vaadin (which is a Finnish word for a female reindeer). A nice connotation comes from Swahili where Karibu means welcome.

Note: For Groovy Vaadin DSL please see the Vaadin Groovy Builder library.

Why DSL?

Just compare the Kotlin-based CommonElementsView with the original Java CommonParts. Both render the Common UI Elements page, yet with Kotlin DSL:

  • The UI structure is immediately visible
  • The code is more readable and much shorter and concise
  • You can more easily copy parts of the UI and paste it into your project

Supports:
