Example Usage

GeolocationMarker example
To add the Geolocation Marker, just instantiate a new GeolocationMarker object, passing the constructor your map object:
var mapOptions = {
  zoom: 17,
  center: new google.maps.LatLng(-34.397, 150.644),
  mapTypeId: google.maps.MapTypeId.ROADMAP
var map = new google.maps.Map(document.getElementById('map_canvas'),
var GeoMarker = new GeolocationMarker(map);

See the example.
Note: This library will only function in browsers supporting the W3C Geolocation API. This excludes Internet Explorer versions 8 and older.
Reference documentation


The source now uses ES6 modules. It may be included in a build with an ES6 import.
The compiled source now uses a UMD pattern so that it is compatible with both AMD and commonjs modules. However, the library depends on the Google Maps API. The maps api must be defined prior to the GeolocationMarker inclusion.
