As Java developers, we know the benefits of type-safety when building apps. The problem? Usually, that type-safety ends when we leave the server. What if it didn't have to be that way?

In this presentation, you'll learn how to build a full-stack reactive web app through live code examples. We'll use Spring Boot and Java on the backend and React with TypeScript on the frontend, connecting the two with the new Hilla framework from Vaadin.

Have you heard about Quarkus ? for sure you have, a new super fast, super light framework to develop cloud native and GraalVM compatible apps. But, is that easy to go the Quarkus way ? is it hard to migrate an existing app ? For sure in a hello world demo this will look fantastic ( they all look that way don’t they ? ) but, in a real app, is that nice ? is that easy ? is that fun ? In this session I will show my experience from scratch migrating an app to Quarkus, using different technologies as Hibernate, Prometheus, Rest, … and also how you can check your current app and see how easy is to migrate using a foss app to analyse it.

Prepare for a journey of reality, failures, and experiences on the universe of Quarkus , at a ludicrous speed.
