#JUGCH
I'll be visiting @jugch.bsky.social next week & talking about: "Your backend deserves a face."! 🇨🇭
No API pain, no JS fatigue – just building modern web UIs in pure Java with @vaadin.com.
Meet me in Bern (3.3.), Lucerne (4.3.), and Zurich (5.3.).
Join me here: www.jug.ch
I'm happy to meet you!
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👇

Building #Java container images always comes down to trade-offs.
On Jan 15, @cat-edelveis.bsky.social and Miikka Andersson will explore approaches to layering, size reduction, and startup time reduction using a Spring Boot + Vaadin app.

Vaadin Signals: The Future of Reactive State Management!
I’m exploring @vaadin.com Signals — a reactive way to manage state across components and even browser tabs. 🌐
Key takeaway:
🔗 Break tight coupling.
⚡ Real-time updates with zero extra effort.
🛠️ Thread-safe

A fix is already available.

If you're affected: please patch!
It is a UI unit test. Instead of running the test from the browser, you can run them in the server only.
@vaadin.com 25 is out!
To celebrate, I built a simple real-time chat app — all in Java, no HTML/JS/CSS.
UI built with Vaadin’s built-in components.

#Figma ➝ real UI in #Java?
@vaadin.com’s webinar (Dec 2) shows how to do it with Copilot or design tokens/components.
Worth a look: pages.vaadin.com/from-design-...
Vaadin uses WebComponents and communicates via websockets and json messages. No web assembly, just maven and npm.
Web UI with just #Java.
Text field → Button → Grid — all in 30 seconds.
No HTML. No JS.

Enjoying todays morning show with @rene-wilby.de, Leif & Miikka talking about Hilla's integration into @vaadin.com Flow.

Disclaimer: No major changes. The core benefits of Flow—server-side UI with Java—will be enhanced, while client-side options will remain available as needed.
🎉 We’re at @devoxx.com Antwerp!
Come visit the @vaadin.com booth and let's chat about building modern web apps in Java, explore what Vaadin can do, and see it in action.
👕 We’ve got T-shirts – come grab one!
💬 The Vaadin crew is looking forward to meeting you.

Later today (12:00 CEST), Matti Tahvonen and I are going to dive into the mix of #SpringBoot, @vaadin.com, and #Pi4J for some #JavaOnRaspberryPi fun. Will you join us?

Sehr cool. Das freut mich sehr zu sehen!!!
Do you prefer reading @vaadin.com docs in Spanish, Chinese, German or Finnish? 📙
We just added AI-supported translations for the Vaadin documentation in those languages.
Not perfect yet – but already surprisingly helpful.

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.
They deserve some Hilla, so I know them in good hands for the next 2 weeks ;)
any reason why full-stack is not welcomed?
I'm mean Flow comes with less boilerplate, type-safe communication and just one programming language.
Sorry to read that. Haven't been Vaadin Flow an option?
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!
