gmaps.js module to manage geofences*.
*A geofence is a polygon that delimits a zone in a map.
For using with bundlers (as Browserify or Webpack):
npm install gmaps.geofences --save
Before require() this module you need to require('gmaps.core').
For using directly in the browser, download the gmaps.geofences.js (or gmaps.geofences.min.js) in dist.
You need to register a <script> tag with the Google Maps JavaScript API, then import gmaps.core.
Every Google Maps map needs a container (<div id="map"></div> in this demo), which needs to have width and height, and be visible (without display: none, for example):
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script src="gmaps.core.js"></script>
<script src="gmaps.geofences.js"></script>
<style type="text/css">
#map {
width: 400px;
height: 400px;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
var map = new GMaps({
el : '#map',
lat: -12.0433,
lng: -77.0283,
zoom: 12
});
var path = [
[-12.040397656836609,-77.03373871559225],
[-12.040248585302038,-77.03993927003302],
[-12.050047116528843,-77.02448169303511],
[-12.044804866577001,-77.02154422636042]
];
var polygon = new google.maps.Polygon({
paths: GMaps.arrayToLatLng(path),
map: mapWithGeofences.map
});
var isInside = mapWithGeofences.checkGeofence(-12.0433, -77.02833, polygon);
console.log(isInside);
</script>
</body>
</html>
For more examples you can check the tests in this repo.
Check if a coordinate (lat and lng) is inside the fence. A fence can be an instance of google.maps.Polygon, google.maps.Circle or google.maps.LatLngBounds. For google.maps.Circle, you need to load the Google Maps API with the geometry library.
Check if a google.map.Marker marker is inside of any of its fences, triggering an outsideCallback if the marker is outside.
