I built something similar, but I managed to compile the Dart VM, its compiler and the static analyzer to wasm using emscripten:

- repo: https://github.com/modulovalue/dart-live

- demo: https://modulovalue.com/dart-live/

It's on my todo list to support compiling dart code through the wasm bundle to wasm directly. Right now it's running the dart arm simulator on the web because it supports hot reload.

I'm wondering if there are any cool use-cases that motivate having the compiler itself run in wasm. I did it mostly for fun and besides building tooling for compiler developers themselves or IDEs, I can't come up with much.

There was one guy that wanted a sandboxed environment for agents as he couldn't find anything else. A few other people used the dart live project to build playgrounds for their own packages.

Who's the target audience for minikotlin? I'm just curious.

In any case, cool project, thanks for sharing!
