Tokamak VS teavm

https://github.com/TokamakUI/Tokamak

I’m also working (slowly) on native Flutter channels:

https://github.com/PADL/FlutterSwift

But this is really targeted at embedded use cases.

There is Tokamak but I don't know how usable it is just yet.

TokamakUI runs via SwiftUI on WASM for web. Apple just hired the creator of the framework.

You can even make web apps by creating web components in swift with Tokamak.

I am playing around with Tokamak just for a bit of fun and learning, and it's been pretty solid so far! Though I want to branch out and play with some dynamic data from a random API, instead of just using mocked/pre-populated data.

There is SwiftWasm that compiles swift into WebAssembly so you can run it in the browser, but swift can't directly manipulate the DOM so you'd still need JavaScript or something like TokamakUI so you can design the front-end portion of your app.

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.
