Was passiert, wenn ein Framework Altlasten entfernt statt neue Features draufzupacken? #Vaadin 25 setzt auf #Java 21, Jakarta EE 11 und einen schlankeren Stack.
@svenruppert analysiert, warum das Upgrades stabiler & Projekte wartbarer macht: https://javapro.io/de/ein-unerwartet-problemloses-upgrade/
Kennst du diese Starterprojekte, die mehr verwirren als helfen? @svenruppert baut ein #Vaadin-Flow-Template, das nur die wichtigen Bausteine sichtbar macht: AppShell, MainLayout, Views, Service, Theme, #i18n...

Schon mal Imports gebaut, die still und heimlich Daten überschreiben? @svenruppert macht im #URLShortener das Gegenteil: Import als sichtbarer UI-Zustand, nicht als Hintergrundprozess. Kontrolle statt Chaos.

Viele Starterprojekte wollen alles erklären: Routing, Security, UI, Themes. Am Ende bleibt wenig hängen. @svenruppert geht einen anderen Weg: ein #Vaadin-Starterprojekt mit Fokus auf die Kernstruktur.

A Vaadin Starter Project with a Clear Focus
Many example projects overload the starting point by covering too many topics at once. Routing, data access, security, forms, theme customisations, and other integrations will then be presented in a single demo. This makes it more difficult for readers to recognise the project's actual structure. This project takes a different approach. The focus is on a compact framework comprising AppShell, MainLayout, several views, a…

Practical i18n in Vaadin: Resource Bundles, Locale Handling and UI Language Switching
Modern web applications are rarely used only by users with the same language. Even internal tools often reach international teams or are used in different countries. A multilingual user interface is therefore not a luxury feature, but an important part of the user experience. The open-source project URL-Shortener also benefits from a clear internationalisation strategy. The…
Separation of Concerns in Vaadin: Eliminating Inline Styles
Vaadin Flow enables the development of complete web applications exclusively in Java. Components, layouts, navigation, and even complex UI structures can be modelled on the server side without working directly with HTML or JavaScript. This approach is one of the main reasons why Vaadin is especially popular in Java-centric projects. However, as a project grows in size, a typical problem arises: styling is…
An unexpectedly hassle-free upgrade
The starting point for this article was not a strategic architecture workshop or a long-term planned migration path, but a comparatively unspectacular step: updating the version numbers in the existing project. As part of further developing my URL shortener project, a regular dependency update was due anyway. Vaadin 25 (was already available at that time, so it made sense to proceed.
The Importance of UI in Import Processes
Why an import needs a UI at all Import functions are often treated as purely technical details in applications. Data is read in, processed and then made available – ideally without further interaction. In practice, however, an import is rarely an invisible process. It marks a transition between existing system states, between old and new data, between trust and control. This is exactly where the need for a user interface arises.
