teavm VS HumbleUI

Joel from our team worked on the initial prototype for WASI support in TeaVM (https://github.com/konsoletyper/teavm/pull/610), and we temporarily forked before the WASI support made it to the official repo.

Good reminder to deprecate that now!

A number of concerns with the viability of the current WASM GC are covered here (Google translation to English):

and the original article:

This is from the author of TeaVM, who has 10 years of experience getting Java and JVM code to run efficiently in the browser. https://teavm.org/

TeaVM's existing transpilation of Java to JavaScript performs well (using the browsers JS GC). It will be interesting to see if WASM GC matures to the point where it is even faster.

Uses this apparently: https://github.com/konsoletyper/teavm

How does this compare to say the TeaVM (https://github.com/konsoletyper/teavm) which I know only has "experimental" WASM support at the moment?

For Java, no WASM file is requested. Maybe the Java code was transpiled to JavaScript, perhaps using TeaVM.

>> It's not like you can take a random JAR and convert it to WASM.

Maybe you can:

TeaVM is an ahead-of-time compiler for Java bytecode that emits JavaScript and WebAssembly that runs in a browser. Its close relative is the well-known GWT. The main difference is that TeaVM does not require source code, only compiled class files. Moreover, the source code is not required to be Java, so TeaVM successfully compiles Kotlin and Scala.

I have never had an opportunity to try out TeaVM, but it seems promising.

For a fast, lightweight, Java-based front-end, try TeaVM and its Flavour toolkit:

https://teavm.org/

It is easy to get started by using the maven archtetype, there's an tutorial in Java Magazine here:

With TeamVM and Flavour you get a full front-end SPA framework that lets you code business logic in Java, and pair that with HTML and CSS to make components.

To see what it can do, check out Wordii, a fast-paced 5-letter word game:

Minecraft contains some native dependencies, though; you'll need something like https://copy.sh/v86/ or https://bellard.org/jslinux/ with the right operating system image to run it in browser.

So you can see, there are really a lot of choices but none of them dominates, which means they all have flaws. You can read a good article from Niki Tonsky where Clojure UI problems are discussed. Also to address the problems Niki Tonsky started the development of a new UI for Clojure, called Humble UI. So now we have one more option :)

If you don't mind being stuck on Windows you could use Visual C# or Visual Basic, they have edit-and-continue too. https://learn.microsoft.com/en-us/visualstudio/debugger/edit... I've worked with the SuperTux C# level editor in the past. C# was actually pretty nice for GUI stuff.

There doesn't seem to be a good GUI framework for Clojure. There was Seesaw but it hasn't been updated since 2019. There is a guy developing a new framework https://github.com/HumbleUI/HumbleUI/ but it's WIP. I guess you could sidestep this by making it a webapp and using figwheel.

Nikita Prokopov is developing Humble UI which is worth keeping a close eye on. (Yes, it's Clojure, but Java interop is bound to emerge if it builds up a critical mass and catches on.)

I've made a few desktop apps in https://github.com/cljfx/cljfx (e.g., https://www.chronos-desk.com/), and cljfx (JavaFX + Clojure) is amazing and makes for rapid development, not to mention fun. I'm keeping an eye on https://github.com/HumbleUI/HumbleUI, which promises to be a step up.
