This is impressive work, snappier than most of the "compile a rich Java GUI to js" systems out there, which can take minutes to start up -- an eternity on the web. While I've used JavaFX on non-trivial projects, the momentum for UX definition seems to have swung towards HTML/CSS. To combine HTML/CSS layout with Java frontend logic, I have switched to Flavour ( https://flavour.sourceforge.io/ https://flavour.sourceforge.io/ ) for all my new projects. (Disclaimer: while I didn't create Flavour, I'm now the maintainer.) Flavour lets you make fast-downloading single-page apps, like Wordii ( https://frequal.com/wordii/ https://frequal.com/wordii/ ). It's easy to get started, there's a maven archetype and easy instructions at https://flavour.sourceforge.io/ https://flavour.sourceforge.io/. Much more documentation is in the Flavour book: https://frequal.com/Flavour/book.html https://frequal.com/Flavour/book.html
