Vaadin, the versatile full stack Java-based framework that is a competitor to Spring MVC, continues to innovate with its new release of v23 which sees the first release of Hilla, the new name for Vaadin Fusion.
Vaadin consists of two frameworks, server-side Flow and in an attempt to lure developers that work say with Angular, a frontend framework introduced as Fusion in Vaadin 15, which allows to do your reactive UI logic in TypeScript while continuing writing the backend in Java.
To disambiguate between the two and make the distinction clearer, Fusion is now called Hilla and has its own website.
This change will make it easier to find relevant documentation easier and not be mixed up with Flow's, allow clearer communication and allow Flow and Hilla to evolve more independently, as Hilla will from now on follow it's own version sequence.
Hilla's main features are :
That aside Vaadin 23 requires Java 11 while the previous release, Vaadin 22 was the last version to support Java 8. This version also includes bug fixes and improvements on the Form Layout configuration and Accessibility as well as defaulting to npm as the frontend package manager.
Vaadin offers the whole package that includes Web components with which you construct your frontend. There are no HTML templates because the views are implemented in Java. But nowdays there's new solutions that decouple the process by using powered up HTML on the client. htmx and Hotwire for example are both stack agnostic and offer html rendering with SPA mentality.
htmx for instance extends the normal html syntax and allows for performing asynchronous requests to the server which in turn responds with html content that htmx will subsequently swap on the client.
There's also hybrid approaches on the rise which carry the advantages of both sides instead of one replacing the other. One such example would be combining server rendering and CSR via rehydration which attempts to smooth over the trade-offs between Client-Side Rendering and Server Rendering by doing both.
Saying that I'm just happy with Vaadin Flow which makes doing web development based solely on Java and web components possible, but it's important to be on the lookout for any new approaches. As always use the right tool for the right job.
