Vaadin 23 will require Java 11
Vaadin 23, releasing in March 2022, will require Java 11. To give users additional time to upgrade from Java 8 to a newer version, we're extending the maintenance period of Vaadin 22 until March 2023. Time flies, and it’s already been 8 years since Java 8 was released. It has also been 4 years ...
Live stream recording: Web components, design systems and accessibility
Web Components are an excellent basis for building Design Systems, but providing good accessibility can seem like a daunting challenge. In this live stream, we were joined by engineers and product owners from Adobe, IBM, SAP, Vaadin, and ING for a panel discussion on the challenges they've faced, ...
JWT authentication with Vaadin Flow - for better developer and user experience
JWT (JSON Web Token) is a popular way to handle authentication in stateless, browser-centric web UIs. Vaadin Flow runs its UI state and logic in the server memory – by design. Without that, Flow users couldn’t have the pure Java developer experience and simplicity they love. At first glance, it ...

Introducing Quarkus support for Vaadin Flow
Quarkus is an increasingly popular Kubernetes-native Java framework. Vaadin Flow users previously had to rely on community add-ons for Quarkus support, but now, with the release of Vaadin 22, the support is official. This change means you can rely on continuous support when building Quarkus apps ...
Improve your development speed with Vite
Vaadin 22 comes with a new experimental feature that allows you to use Vite for the front-end build instead of webpack. The development server startup should be faster, and the changes you make to your code should be visible faster in the browser. We have observed significant improvements to build ...
