Usage

var publicConfig = {
  key: '<YOUR-KEY>',
  stagger_time:       1000, // for elevationPath
  encode_polylines:   false,
  secure:             true, // use https
  proxy:              'http://127.0.0.1:9999' // optional, set a proxy for HTTP requests
};
var gmAPI = new GoogleMapsAPI(publicConfig);

// or in case you are using Google Maps for Work
var enterpriseConfig = {
  google_client_id:   '<YOUR-CLIENT-ID>', // to use Google Maps for Work
  google_private_key: '<YOUR-PRIVATE-KEY>', // to use Google Maps for Work
  google_channel:     '<YOUR-CHANNEL>' // to use Google Maps for Work application usage tracking
  stagger_time:       1000, // for elevationPath
  encode_polylines:   false,
  secure:             true, // use https
  proxy:              'http://127.0.0.1:9999' // optional, set a proxy for HTTP requests
};
var gmAPI = new GoogleMapsAPI(enterpriseConfig);

// geocode API
var geocodeParams = {
  "address":    "121, Curtain Road, EC2A 3AD, London UK",
  "components": "components=country:GB",
  "bounds":     "55,-1|54,1",
  "language":   "en",
  "region":     "uk"
};

gmAPI.geocode(geocodeParams, function(err, result){
  console.log(result);
});

// reverse geocode API
var reverseGeocodeParams = {
  "latlng":        "51.1245,-0.0523",
  "result_type":   "postal_code",
  "language":      "en",
  "location_type": "APPROXIMATE"
};

gmAPI.reverseGeocode(reverseGeocodeParams, function(err, result){
  console.log(result);
});

Static Maps

var gmAPI = new GoogleMapsAPI();
var params = {
  center: '444 W Main St Lock Haven PA',
  zoom: 15,
  size: '500x400',
  maptype: 'roadmap',
  markers: [
    {
      location: '300 W Main St Lock Haven, PA',
      label   : 'A',
      color   : 'green',
      shadow  : true
    },
    {
      location: '444 W Main St Lock Haven, PA',
      icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=cafe%7C996600'
    }
  ],
  style: [
    {
      feature: 'road',
      element: 'all',
      rules: {
        hue: '0x00ff00'
      }
    }
  ],
  path: [
    {
      color: '0x0000ff',
      weight: '5',
      points: [
        '41.139817,-77.454439',
        '41.138621,-77.451596'
      ]
    }
  ]
};
gmAPI.staticMap(params); // return static map URL
gmAPI.staticMap(params, function(err, binaryImage) {
  // fetch asynchronously the binary image
});

This example prints the URL for the Static Map image: "https://maps.googleapis.com/maps/api/staticmap?center=444%20W%20Main%20St%20Lock%20Haven%20PA&zoom=15&size=500x400&maptype=roadmap&markers=color%3Agreen%7Clabel%3AA%7Cshadow%3Atrue%7C300%20W%20Main%20St%20Lock%20Haven%2C%20PA&markers=icon%3Ahttp%3A%2F%2Fchart.apis.google.com%2Fchart%3Fchst%3Dd_map_pin_icon%26chld%3Dcafe%257C996600%7C444%20W%20Main%20St%20Lock%20Haven%2C%20PA&path=weight%3A5%7Ccolor%3A0x0000ff%7Cenc%3A%7BbbzFfyvwMnFwP&style=feature%3Aroad%7Celement%3Aall%7Chue%3A0x00ff00"

By giving gm.staticMap an optional callback, you can retreive the static map PNG data:

You will get a map like:

For custom markers using the icon parameter, a little-known scale parameter is also available that makes it possible to use high-resolution custom images on devices with retina displays. Set it to 2 and use it together with a @2x http-only image URL (Google's API does not support custom marker images served over https), such as:

{
  location: '999 Example Road, Earth',
  icon: 'http://example.com/path/to/custom-marker@2x.png',
  scale: 2
}

Street view

var gmAPI = new GoogleMapsAPI();
var params = {
  location: '51.507868,-0.087689',
  size: '1200x1600',
  heading: 108.4,
  pitch: 7,
  fov: 40
};
var result = gmAPI.streetView(params);
