Nearest Layer in Leaflet

[New Leaflet User]

I have 2 Layers (Customers & Suppliers), I want to get the nearest suppliers to a specific customers,can anyone help me in that with example?

Thanks in advance.

You need to use the Havesine formula to calc distance between Customers and Suppliers. To make sure you're not running too big of a loop, use a bounding box to narrow your results before you run through and check distances.

Take a look at the turf js library. It will do what you are looking for, though you may have to tweak their examples. There is an example here - you will have to adjust abut for using leaflet instead of mapbox. - https://www.mapbox.com/help/analysis-with-turf/
