I've been using Spring Boot for a very long time. I learned the JavaScript framework, Vue.js, in order to build a modern web app that's been in service for about 7 years.

Vaadin is an open source framework for building modern web apps in pure Java. I recently refactored the application so that it's end-to-end Java.

In this talk, I share the experience and dive into real-world challenges going from a frontend JavaScript to using Java all the way.

I cover coding, security, testing, debugging, and migrating. The pace is quick and you learn a lot in this session as we kick JavaScript to the curb!
