Hello, add-on authors! This is the Vaadin 24 and Spring Boot 3 period. Although Vaadin 24 has only been in the pre-release stage for a few months, users are already anxious to try out Spring Boot 3, so we anticipate that Vaadin 24 pre-releases will see more usage than pre-releases often do. ...

TL;DR: The Java enterprise application ecosystem at large is making a backward-incompatible leap from the javax.* namespace into jakarta.*. To use next-generation application frameworks like Spring Boot 3 or Jakarta EE 10 compatible application servers, you'll need to use the soon-to-be-released ...

Vaadin 23.2 is already available as a release candidate. Along with some UI component enhancements, it comes with a couple of noticeable improvements to the core framework, Vaadin Flow.

The Web Bluetooth API is one of the interesting new technologies that the Google Chrome team has cooked up that further narrows the gap between web apps and “real” apps.

This is probably the place to ...

Time is money. Something that I still don’t get is that many Java developers spend a lot of it (time and money) while waiting to see their latest code changes in action. JVM is known for its great peak performance when serving large numbers of users, but our tooling isn’t by default that well ...

Last Thursday, together with Leif Åstrand from our product management, we held a webinar about our roadmap. The idea for the webinar was sparked by the changes we recently did for how we work in our R&D teams. Work is now split into 6-week projects, which are chosen relatively close to the ...

JVM is a monster – in a good way. Its architecture and especially the super-optimized just-in-time-compiler (JIT) help Java byte-code apps to run at a performance that makes startups rewrite their entire software when they grow up. But this amazing piece of engineering doesn’t come without a price. ...

Quarkus is an increasingly popular “container-first” Java framework by RedHat. Similarly to Spring Boot, there is no application server, but the server is part of your generated artifact. The first integration examples with Vaadin and Quarkus were written by Sven Ruppert early in the 0.x phase and ...
