Was hoping this was about WebAssembly/WASM. You used to be able to import rust directly into your JS with Parcel, but sadly that feature was dropped in Parcel 2. Is there a simple pipeline for compiling and typesafe binding of Rust-WASM?

It's pretty straight forward to include the output of `wasm-pack` into a vite project. The output is a node module in a folder with the wasm files and a single "main" JS file.

Because I wanted to load WASM in a web worker for my project [1] I needed to use vite-plugin-wasm and `wasm-pack build --target web` but without that constraint you should be able to import the main JS file from the wasm-pack output directory using wasm-pack's default `bundler` target and no vite plugins.

I'm literally building a project right now that executes compiled WASM Components, theoretically written in any language but right now I'm using Rust for both parts (the "runner" and the WASM Components).

But, I did a brief exploration to see how I could compile those WASM Components in any language (including JavaScript), and as far as I can tell, if you could use ComponentizeJS + jco for compiling JavaScript to WASM Components, and if you need to run them in JavaScript too, StarlingMonkey seems to be able to handle that.

I'm not sure about the last part, typesafe bindings would require you to use TypeScript or similar, not just JavaScript. I don't use TypeScript myself so I don't know if the approach above would give you any type safety on the Component-implementation side.
