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.

I want to confess a sin: I should be working on my talk on Docker images, but instead, I'm playing around with @vaadin.com and can't get enough of it😅❤️‍🔥

Hilla and Kafka. Part 3: Kafka Streams Using Kafka Streams and Interactive Queries to consume, aggregate and query streaming data in the Hilla backend and visualize the data in the Hilla frontend in a reactive way.

New blog post: Using Kafka Streams and Interactive Queries to consume, aggregate and query streaming data in business web apps built with #Hilla (by @vaadin.com).

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.

Sharing made simple: Integrating the Web Share API with Vaadin | Vaadin Add native sharing to your Java web app with the Web Share API. Boost UX on mobile with one-click link sharing in Vaadin Flow apps.

💡 Did you know you can add native sharing to your #Vaadin app with just one line of Java?

The Web Share API can be triggered from #Java using Page.executeJs—super handy for mobile users who expect a built-in share button.

See how it works 👉 vaadin.com/blog/sharing...

Hilla and Kafka. Part 1: Consuming messages Consuming Kafka messages using Spring Kafka and Spring Boot's auto-configuration capabilities in the Hilla backend and displaying these messages in the Hilla frontend UI in a reactive way.

New blog post: How to consume and display Kafka messages in a reactive way using #SpringKafka, #SpringBoot, #React and #Hilla (by @vaadin.com) 👇

Judge me.

I’ve been using Spring Boot with Vaadin to build a typical reactive web app, sort of thing React gets used for.

I like it, it feels way more solid than flaky JS and bundling. Also does hotswap and is of course statically typed (as all good languages are).

I’m smitten.

New components, less boilerplate — what’s new in Vaadin 24.8 | Vaadin Vaadin 24.8 helps full-stack Java developers build modern apps faster with reactive UIs, smarter file handling, and built-in DevOps tools. See what's new!

Ready to ship modern, accessible #Java apps faster?

I created a @vaadin.com app using @windsurfai.bsky.social without writing a single line of code! I’m impressed 😎
I started on start.spring.io adding the dependencies (Vaadin, JPA, Postgres, Testcontainers, Flyway). Then I used the chat assistant.

Long-running tasks in the UI? With @vaadin.com, you can run server-side processes async and push updates to the client – without blocking the UX.

✅ UI stays responsive
✅ Real-time updates
✅ No manual polling overhead

Here is a short video to see how easy it is! 🎬👇

Playing around with Spring AI MCP and @vaadin.com. Created an app that can modify itself while running 😅

Set your page title in @vaadin.com with just one annotation! 🎯

But there’s more:
✅ Dynamic titles for localization
✅ Programmatic PageTitle to update it at runtime

Give your users the right context—without complex frontend code! 🚀
