Mamba in the browser can be used in conjunction with python compiled to wasm from emscripten-forge
The usage looks like:
import picomamba
def callback(name, done, total):
percent = 100.0 * done / total
print(f"{name} {percent:.2f}% ({done}/{total})")
pm = picomamba.PicoMamba(
env_prefix=env_prefix, # the name of the env
arch_root_url=arch_url, # root url for arch pkgs
noarch_template=noarch_template, # templated url for norach pkgs
progress_callback=callback, # report download progress
)
await pm.fetch_repodata(
arch_url=arch_url, # url for arch repodata tar.bz2 file
noarch_url=noarch_url # url for noarch repodata tar.bz2 file
)
transaction = pm.solve(
["regex", "imageio", "numpy", "networkx"]
)
await pm.install_transaction(transaction)
import numpy
import regex
import networkxthe output would be

This is all very experimental and far from usable!!!
