Get layer data from polygons in Draw plugin

Problem description

Hi, I’m using Folium with the Draw plugin to draw and export geojson data in Jupyter. I’m aware of the “Export” option in the Draw plugin, however I’d prefer to export the draw polygons programmatically. Is there a way I can directly access drawn objects?

When I run the above code in Juypter and draw a polygon onto the map I would expect the map object to update or for there to be some event I can listen to in order to my own state of what polygons are on the map.

Output of folium.__version__

‘0.11.0’

I’m afraid I can’t really help you here. Being a folium maintainer doesn’t mean I develop all new features that are requested.

One thing to keep in mind that in general folium is a one-way street from Python to Javascript, so if you want to get it back in Python that’s tricky.

The suggestion to use drawnItems makes sense. Maybe you can write some Javascript and add it to the template that stores it to disk any time a change is made or something.

I’m going to close this issue since it goes a bit beyond the scope of folium. If somebody has more insight on this, or wants to share some code snippets, please do share them though!
