Is there any library written in JavaScript for offline routing, to generate routes based on OSM data? And is there any with leaflet support?
回答1:
While not generally advised (see scai's comment above), you actually can do offline routing in JavaScript, for example by using graphhopper cross-compiled to js or any of these libs.
