Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rust + WASM + Typescript [+ React]
There are many options, but what worked best for me is compiling with cargo-wasi and loading the resulting Wasm file with browser_wasi_shim. Using wasm32-wasi instead of wasm32-unknown-unknown requires a bit more work (the communication with JS has to be set up manually), but gives the flexibility of having just a Wasm file that can be dropped in and loaded dynamically. (There's wit-bindgen for generating wrapping code according to an interface definition but I didn't have much success with it.)

Extending web applications with WebAssembly and Python
The webassembly-language-runtimes is focused on providing WASI-based language interpreters, what would require a WASI polyfill at the browser level (https://wasi.dev/polyfill/) and (https://github.com/bjorn3/browser_wasi_shim).
Pyodide is certainly another option, but is emscripten based, not based in webassembly-language-runtimes or WASI.

The Tug-of-War over Server-Side WebAssembly
Indeed, some people are doing this:
- WASI once had an official polyfill https://wasi.dev/polyfill/, now apparently succeeded by https://github.com/bjorn3/browser_wasi_shim
- wasmer-js provides a JS polyfill for WASI https://docs.wasmer.io/integrations/js/wasi
- Cloudflare has a WIP polyfill https://github.com/cloudflare/workers-wasi
I'm generally leery of non-temporary polyfills, so I'm not sure that any of these feel like a long-term viable option for me.

Browser to Haskell Wasm Reactor Module Communication Example
Browser client library uses browser_wasi_shim to communicate with the module.

The New Wasmer JavaScript SDK
});
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"

Try the wasm port of pointfree
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.

WebAssembly backend merged into GHC
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.

Show HN: I built a WASI playground for running CLI binaries in the browser
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.

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? :-)
