teavm VS daedalOS

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):

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.

I've learned so much while making this project into my personal website (dustinbrett.com). It's made me a much better web developer as I have tried to emulate a desktop environment with pixel perfect accuracy using CSS, HTML & JavaScript.

I'm very happy to announce that my personal website has once again been nominated for a Webby Award!

This has also been ported to the web via Emscripten. I host it on my website if anyone wants to play. https://dustinbrett.com/?app=SpaceCadet

As someone who built a website around this idea, I agree! The desktop metaphor is powerful. If anyone wants to check it out it's at https://dustinbrett.com

Very cool! It's always refreshing to see the "OS in the browser" projects that try and actually make something functional. I've been working on one myself for nearly 3 years now, called daedalOS (https://github.com/DustinBrett/daedalOS).

The WASM kernel idea is very cool and I hope one day to be able to add something similar to my project. I think you are onto something and I am excited to see your progress as you implement the GUI.

If you want some Browserception, my desktop environment (https://dustinbrett.com/) can indeed do this. But after a few levels in Chromium you need to add a random query string (/?a=1) to the URL otherwise it stops working.
