Vaadin 25.1 brings reactive state management to Java—define your state once, and your UI stays in sync automatically.
#Java #FullStack #WebDev #ReactiveProgramming
Why was our Grid suddenly 7x slower?
Spoiler: CSS.
In this post, we walk through how small CSS decisions (like box-shadows and selectors) can massively impact performance at scale—and how we fixed it in Vaadin 25.

Can you use #Vaadin inside an @angular.dev app?
Yes—and it might simplify your architecture.
This post shows how to:
• Export Vaadin components as Web Components
• Embed them into Angular
• Move complex UI logic to #Java
👉 See how: vaadin.com/blog/embeddi...

If you missed Miikka Andersson’s session with @edelveis.dev on Docker images for #Java apps, he turned it into a solid write-up. Multi-stage builds, layered JARs, buildpacks, AOT cache, native images, hardened runtime images: vaadin.com/blog/buildin...
In our recent webinar “What is possible on the web in 2026”, Matti Tahvonen explains why it’s time to ditch passwords—and what makes passkeys a better, more secure alternative.

Curious what it looks like to run a Java Swing app in the browser?
Miikka Andersson and Eftun Türkmen will demo it live and talk about modernizing Swing apps without a full rewrite.
Join us: www.youtube.com/watch?v=3q_s...
Lazy loading in Vaadin is this easy:
Instead of loading all tasks into a grid, we can use setItemsPageable(...) to fetch data as needed and improve scalability, startup responsiveness, and backend efficiency.

Still maintaining a #Swing app?
You don’t need to rewrite it to move to the web.
In this webinar, we’ll show how #Java teams modernize Swing apps bit by bit — with a live migration demo.

Vaadin Dark Mode - 1 Line (Java Web App)
Switch color schemes instantly in a #Java web app with Vaadin—no reload.
@ColorScheme for the initial scheme
setColorScheme(...) to switch at runtime
System sync reacts to OS appearance changes.

Do modern web apps really need a huge stack?
At #JavaOne 2026, XDEV explores a different approach: building enterprise-ready UI and persistence mostly with Java using @vaadin.com and EclipseStore.
📅 Drop by the Hack Haus and challenge the idea of “full stack”.

In the upcoming Vaadin 25.1 release, browserless UI tests will be part of our free offering — Apache 2.0 licensed, just like the core framework.
Test component state, events, routing, and UI logic directly inside the JVM.

What can modern browsers do in 2026? 🤔
Bluetooth. USB. Printers. Offline. Native-like UX. Enterprise security.
This Wed 3 PM CET, Matti Tahvonen goes live on YouTube to show how #Java teams can build modern web apps - without frontend chaos.

Sometimes you need client-side logic in a Vaadin app but really don't want to switch to JavaScript. Matti Tahvonen compared four ways to run Java in the browser — GWT, TeaVM, CheerpJ, and GraalVM WASM — by building Tetris with each one.

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👇

We had a great webinar with @vaadin.com on creating a perfect container image for #Java, covering image size, JAR layering, memory consumption, startup, and image hardening.
