When referencing the google map API documents, it is common practice to use script tags which make the google map instance a global variable. But is there a way to access the map instance without it being global?
The npm/bower package angular-google-maps, on the other hand, does not rely on script tags. However, it has become unmaintained and as a result, the project I am currently working on is in the process of migrating away from it.
One way to incorporate the map is by encapsulating it within a module.
Consider the following example:
var myModule = (function(){
var map = null;
var initializeMap = function(){
map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: {lat:1, lng:1}
});
return {
initializeMap: initializeMap
};
})();
Subsequently, in your HTML script tag:
<script async defer src="https://maps.googleapis.com/maps/api/js?key=API_KEY&callback=myModule.initializeMap"></script>
Your "myModule" module may need to be globally accessible for functionality reasons, although alternate methods might exist. This approach was the first that sprung to mind.
