Install on Pyodide/JupyterLite

It would be really cool to run leafmap on Pyodide and hence JupyterLite using micropip.

I gave it a try and found basically two issues with non-existing Python 3 source wheels (needed by micropip) for pycrs and pyshp on PyPI for which I’ve created these tickets (but there might be wheels for them hosted somewhere else): https://github.com/karimbahgat/PyCRS/issues/56 and https://github.com/GeospatialPython/pyshp/issues/217. And here-map-widget-for-jupyter can be installed, too, but still has some issue with the JupyterLab extension, as described on https://github.com/heremaps/here-map-widget-for-jupyter/issues/25. Folium can be installed in a somewhat complicated manner, see the notebook pyolite folium.ipynb on JupyterLite.

Not sure if anything else is needed… 😉

@deeplook this is great news. @giswqs leafmap would be awesome on pyscript, just in time as the binder builds are now heavy and take a while.

pyscript map html file & demo: https://github.com/ryanking13/geopandas-pyodide-test/blob/main/index.html https://ryanking13.github.io/geopandas-pyodide-test/

@ryanking13 thanks for this poc.

@jtpio Thank you for the suggestion. I have made jupyterlab and ipysheet as optional dependencies, now leafmap can be installed easily using piplite.

Try it out at https://demo.leafmap.org

%pip install -q leafmap
