Google Maps not displayed on Navigation

[richardmarais]

I’m a bit confused. I am using google.maps.Map, but the above article talks about plugin.google.maps.Map. Which should I use?

If I use plugin.google.maps.Map, I get:

[ts] 
Cannot find name 'plugin'.
any

If I use google.maps.Map, then backgroundColor() is undefined.

let mapOptions = {
  center: bound.getCenter(),
  maxZoom: 15,
  backgroundColor: 'transparent',
  mapTypeId: google.maps.MapTypeId.ROADMAP
};

var htmlElement: HTMLElement = document.getElementById("map");
this.map = new google.maps.Map(htmlElement, mapOptions);
