A Micropip specific index_url

[MRYingLEE]

Is it possible to create a micropip specific index_url for micopip to speed the compatibility checking in installing?

The index_urls does not need to be updated at real time to follow pypi. Instead, after each version of micropip, update it.

Any ideas?

Any package index that follows simple repository API will work with micropip. We don't have a goal to make one because of a lack of human resources and money, but feel free to implement one if you are interested.

I believe @CNSeniorious000 has some similar idea (pyodide/pyodide#5004) too.

Yeah! I think it's feasible but not a small project either.

However, I do have a tiny project where I use uv for pypi resolution, and the performance is quite good (resolving Jupyter dependencies takes about 800ms). This might be the most cost-effective workaround 😂

If you deploy such a service behind a Cloudflare cache, it's basicly at zero cost.
