If your #JavaSwing app is costly to update, hard to distribute, or UX-limited, the question isn’t if you modernize — it’s how. Swing Modernization Toolkit lets you run Swing in the browser & modernize incrementally all in #Java. See how it works👇 🔗 vaadin.com/blog/announc...

It is a UI unit test. Instead of running the test from the browser, you can run them in the server only.

Vaadin uses WebComponents and communicates via websockets and json messages. No web assembly, just maven and npm.

I started playing with @vaadin.com and @quarkus.io today and I have to say I was surprise just how easy it was to build a UI! My years of Swing experience may be helpful, but it was super easy.

any reason why full-stack is not welcomed? I'm mean Flow comes with less boilerplate, type-safe communication and just one programming language.

Oh really? I always felt the opposite — web apps are way easier to manage. No install hassle, updates just work, and you can deep-link anywhere with a simple URL. And with Vaadin, you just drop the JAR and you’re good to go — feels very lightweight to me! What part of desktop dev do you miss most?
