wasmer-js VS WASM-ImageMagick

});

I was then able to just use this code example with one caveat (https://github.com/wasmerio/wasmer-js?tab=readme-ov-file#use...)

I had to update the SDK import with crossorigin="anonymous"

I use https://github.com/wasmerio/wasmer-js and while v0.12 works fine, v1.2 never returns and is stuck in a busy loop internally somewhere. I did not bother bisecting it because the API changed at v1.0.

You can run WASI/WASM modules in the browser using e.g. the (rather simplistic) official WASI polyfill or the more fully-featured wasmer/wasi. So while htis is certainly a bit more combersome than a direct JS FFI, you should already be able to interact with WASI/WASM-compiled Haskell code from JS.

Good spotto! That's the WASI runtime from wasmerjs (https://github.com/wasmerio/wasmer-js).

That's not the WASI runtime being used in this playground. The one in this playground is @runno/wasi-motor (https://github.com/taybenlor/runno/tree/main/packages/wasi-m...). I haven't released it as an NPM package, but it's all MIT so feel free to copy it.

WASI Modules via Wasmer JS

I have good news! Wasmer can also be run on the browser. Check out wasmer-js [1]

Maybe wasmer-js could be used by Deno to provide WASI support inside their engine? :-)

Image Conversion via WASM-ImageMagick

I've gone with ImageMagick ported to WebAssembly to do basically the exact same things as with FFMpeg, but with a tiny bit less locking up. In the future I would like to get these things running in multithreaded Web Workers as well as have the ability to easily configure transcode settings to whatever is desired instead of the defaults as it is now.

When it comes to audio/video the trusted tool that is often used on the desktop is FFmpeg and this too has been ported to run in the browser, although if you want multithreading you will need to make sure you have special CORS headers enabled to gain access to the SharedArrayBuffer. For images on desktop there is the popular ImageMagick which indeed also has been ported.

ImageMagick is the go to for these kinda things and apparently there is a WASM version: https://github.com/KnicKnic/WASM-ImageMagick
