Vaadin recently announced the discontinuation of Hilla as a stand-alone product. To me, this marks the end of an ambitious project and a personal journey.

Using Kafka Streams and Interactive Queries to consume, aggregate and query streaming data in the Hilla backend and visualize the data in the Hilla frontend in a reactive way.

Describing and comparing four approaches to implement the common Master-Detail-View pattern for business web apps using Hilla.

Creating Kafka messages using Hilla’s first-class form support and type-safety in the frontend and Spring Kafka and Spring Boot’s auto-configuration capabilities in the Hilla backend.

Consuming Kafka messages using Spring Kafka and Spring Boot’s auto-configuration capabilities in the Hilla backend and displaying these messages in the Hilla frontend UI in a reactive way.

Displaying application information in the frontend of a Hilla app is a useful pattern. By combining Gradle, Netflix’s Nebula release plugin and Vite’s environment variable capabilities this pattern can be implemented easily.
