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

I recently learned Vaadin and 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, but you learn a lot!
