Pure Python wheel or WASM/Emscripten build

[psychemedia]

I would like to be able to use rapidfuzz in WASM / Pyodide backed notebook environments such as JupyetrLite and marimo notebooks.

Is there any chance of getting a pure Python wheel for rapidfuzz, or a WASM/Emscripten compiled wheel?

Yes I could build both pure python wheels and wasm compiled wheels. The pure Python wheels are much smaller (somewhere around 60kb vs 777kb). However the compiled wheel should be faster (I didn't test that though).

So I think it would likely make sense to publish both versions so users can select based on their usage.
How are wheels for pyodide usually published?

In pyodide, if the PyPi wheels are universal, they can be installed using micropip. I think distribution of wasm32-emscripten wheels is still a niche thing, although cibuildwheel has supported the wasm32 target for some time.

As to getting packages into pyodide, I think that is managed by requesting inclusion via an issue to the pyodide repo.

I published a new version that properly builds for pyodide. There are already requests to add it to pyodide (pyodide/pyodide#4994) and emscripten-forge (emscripten-forge/recipes#1270). So hopefully it will get added there soon.

In the meantime you can use the attached wheel and just host it yourself.

pyodide-wheel.zip

Fantastic, thanks.

From a quick upload test to JupyterLite, neither the zip nor the wheel can be imported using micropip.install(). I'm not sure if this is a wheel name convention thing or something other.

I don't know much about the pyodide ecosystem. I used the attached test environment. There I did run:

• python cors_server.py to make the wheel available with a working access control
• opened the index.html in a browser

This did work for me:

testEnv.zip

This was probably because we changed the ABI tag from emscripten_X_Y_ZW to pyodide_YYYY_N. Linked issue: pyodide/micropip#158
