webfx VS jfx

There's this: https://github.com/webfx-project/webfx. But it uses GWT which is not maintained (actively) anymore.

For JavaFX on web there is WebFX, Gluon Promise, and JPro.

WebFX - a JavaFX to JavaScript transpiler - can now access local files, as you can read on this GitHub discussion, with a demo on files.webfx.dev.

There is also https://github.com/webfx-project/webfx doing that: https://spacefx.webfx.dev/ compared to server-side rendering wit jpro https://demos.jpro.one/spacefx.html

It's not gluons project. And your words contradict themselves. If it is mirrored from a server, turning off the internet connection would freeze the game. It runs on the browser, and obviously it'll be cached after loading it once? Your words really make no sense. It's a good transpilation, that's why it's small... Can you just accept it? https://github.com/webfx-project/webfx

Important message in the release notes: "JavaFX 20 is compiled with --release 17 and thus requires JDK 17 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read."

GitHub

JavaFX 17 requires at JDK 11 or later (release notes), so the short answer is that you can't do this.

JavaFX has been open-sourced after Oracle dropped it, and it's still in active development (they just released version 19 a month ago, see https://openjfx.io and https://github.com/openjdk/jfx). Also Gluon (https://gluonhq.com) made the toolchain to compile it into native apps for Linux, macOS, Windows, Android & iOS. So with now WebFX compiling it to the web, you get a fully cross-platform UI toolkit that lets you target all major platforms (Desktops, Web, Tablets & Mobiles) from a single Java code base. That's why I think it is interesting, especially for Java developers.

On the JavaFX mailinglist this thrilling message appeared: "Create release notes for JavaFX 19." And yes, they are available now on GitHub! If you want to keep following what’s happening inside the JavaFX community, you can suscribe to it via mail.openjdk.org/mailman/listinfo/openjfx-dev. As with previous releases, the JavaFX community once again succeeded in keeping the 6-months release cycle going on, with a long list of improvements and fixes!
