Research direction

Start at map.save() and inspect how default_js and default_css dependencies are selected and written into exported HTML. Define the required option and verify that JavaScript, CSS, and icons are embedded as inline base64 URIs so the resulting map works without external or relative resources.

Description

enhancement

Is your feature request related to a problem? Please describe.

folium maps exported as html still depend on external leaflet dependencies (either from internet or on relative paths - manual modification is needed)

Describe the solution you'd like

Something similar to knit in RStudio (which produces the html with the inlined resources). I believe the R leaflet package is self-contained (it contains leaflet's resources), so for this to work in the same manner in folium, additional options to override default_js/default_css may be necessary (i.e. to point them to relative/static paths).

Describe alternatives you've considered

Out of various leaflet wrappers, RStudio's implementation is the closest.

Additional context

(Could attach one of html files created through RStudio's leaflet, if anyone needs it)

Implementation

Possibly, just to gauge the interest for now
