harfbuzzjs VS webassemblyjs

There is a well maintained Wasm build of harfbuzz: <https://github.com/harfbuzz/harfbuzzjs> with both OpenType and AAT shapers support, which should be enough but you can also provide your own shaper implementation in Wasm yes.

We're successfully using Wasm harfbuzz to render text in a web-based design tool with relatively high usage so there should be no issues integrating it :)

I was researching how to get a WASMified version of harfbuzz into my frontend 2d canvas library (because: text implementation in the 2D Canvas API is genuinely dire) when I discovered this issue had already been addressed back in 2019, when the guy who develops Photopea asked the question and got a positive answer - https://github.com/harfbuzz/harfbuzzjs/issues/10

So now, to try to dig ourselves out of this fuckery we have to build emulation layers for the considered solution to run on the stupid solution.

https://github.com/xtuc/webassemblyjs/issues/718 looks like it showed up in a fuzzing test on WASM too. Maybe a big with something upstream?

There's no reason you can't just use a JS-based WebAssembly interpreter for Argon2 hashing. I'm pretty sure there are ways to actually use pure WASM or Rust in Cloudflare Workers too. But to be honest I can't think of any use cases where you'd need to run such an expensive hashing algorithm in a Cloudflare Worker; if you're trying to hash passwords this isn't the right solution anyway.
