Introduction
In this article, we will learn how to create navigation direction map (route by route) using MAPBOX.
If you have not seen the Mapbox Integration then I recommend you to refer that first.
Let’s Begin.
Find Current Location Option In Map
map.addControl(new mapboxgl.GeolocateControl({
positionOptions: {
enableHighAccuracy: true
},
trackUserLocation: true
}));
Output:
