Leaflet: GraphHopper test

I am trying to build a code that could draw lines following roads. A lot of tools are existing for this but I wanna learn and do my own. Of course I am using other tools like Leaflet-Routing-machine and GraphHopper via lrm-graphhopper.

• I could create an example of adding markers, being able to drag them and remove them with right clik (here the CodePen)
• A first try of using GraphHopper by adding points. I have an array with the data from the points but this one is not dynamic when the routing is done …
