Vaadin-on-Kotlin (VoK) is a web application framework for building database-backed applications in Kotlin. It combines Vaadin’s component-oriented user interface model with Kotlin-friendly APIs and a modular architecture.
The framework does not impose MVC, dependency injection or a service-oriented architecture, and does not require Spring or Java EE. Its persistence layer uses ktorm and ktorm-vaadin, although developers can substitute JPA, Hibernate or a NoSQL data store.
This is free and open source software.
