I have a javascript applications(Angular4) in which i am trying to import a module, and load it properly (the one in the snippet).
The module is for solve overlapping in googlemaps, i am using the module of this entry: Angular spiderfier However when i do the things it mentions to get the module it fails and the variable overlappingMarkerSpidifier is undefined
oms = require('../../../../../assets/oms2.js');
this.overlappingMarkerSpidifier = getOms.call(oms().prototype, this.map);
oms().prototype seems ok:
{VERSION: "0.3.3", keepSpiderfied: false, markersWontHide: false, markersWontMove: false, nearbyDistance: 20…}
¿What I am doing something wrong?
