    Geolocator.js is a utility for getting geo-location information, geocoding, address look-ups, distance & durations, timezone information and more...

    Features

    • HTML5 geolocation (by user permission) with improved accuracy.
    • Location by IP
    • Reverse Geocoding (address lookup)
    • Full address information (street, town, neighborhood, region, country, country code, postal code, etc...)
    • Fallback mechanism (from HTML5-geolocation to Geo-IP lookup)
    • Watch geographic position
    • Locate by mobile information
    • Get timezone information
    • Get distance matrix and duration information
    • Calculate distance between two geographic points
    • Various geographic conversion utilities
    • Get client IP
    • Fetched location includes country flag image (SVG) URL
    • Language support (depends on the service provider)
    • Supports Google Loader (loads Google APIs dynamically)
    • Dynamically create Google Maps, on demand (with marker, info window, auto-adjusted zoom)
    • Get static Google Map (image) URL for a location
    • Non-blocking script loading (external sources are loaded on the fly without interrupting page load)
    • No library/framework dependencies (such as jQuery, etc...)
    • Universal module (CommonJS/AMD..)
    • Small file size (9KB minified, gzipped)
    • Browser Support: IE 9+, Chrome, Safari, Firefox, Opera...

    Get Geolocator.js

    • Link or download via CDNJS.
    • Download full source code from GitHub releases.
    • Install via Bower: bower install geolocator
    • Install via NPM: npm install geolocator

    Usage:

    Example below, will attempt to get user's geo-location via HTML5 Geolocation and if user rejects, it will fallback to IP based geo-location.

    Inside the <head> of your HTML:

    <script type="text/javascript" src="geolocator.min.js"></script>
    <script type="text/javascript">
     
        geolocator.config({
            language: "en",
            google: {
                version: "3",
                key: "YOUR-GOOGLE-API-KEY"
            }
        });
     
        window.onload = function () {
            var options = {
                enableHighAccuracy: true,
                timeout: 5000,
                maximumWait: 10000,     // max wait time for desired accuracy
                maximumAge: 0,          // disable cache
                desiredAccuracy: 30,    // meters
                fallbackToIP: true,     // fallback to IP if Geolocation fails or rejected
                addressLookup: true,    // requires Google API key if true
                timezone: true,         // requires Google API key if true
                map: "map-canvas",      // interactive map element id (or options object)
                staticMap: true         // get a static map image URL (boolean or options object)
            };
            geolocator.locate(options, function (err, location) {
                if (err) return console.log(err);
                console.log(location);
            });
        };
     
    </script> 

    If you've enabled map option; include the following, inside the <body> of your HTML:

    <div id="map-canvas" style="width:600px;height:400px"></div>

    Read API documentation for lots of other features and examples.

    Important Notes

    • Since Geolocation API is an HTML5 feature, make sure your doctype is HTML5 (e.g. <!DOCTYPE html>).
    • Make sure you're calling Geolocation APIs (such as geolocator.locate() and geolocator.watch()) from a secure origin (i.e. an HTTPS page). In Chrome 50+, Geolocation API is removed from unsecured origins. Other browsers are expected to follow.
    • Although some calls might work without a key, it is generally required by most Google APIs (such as Time Zone API). To get a free (or premium) key, click here. After getting a key, you can enable multiple APIs for it. Make sure you enable all the APIs supported by Geolocator. (If you don't have a key, you can still use Geolocator like the previous versions, but with limited features.)
    • Geolocator now uses a single Geo-IP provider (Nekudo, based on the Maxmind GeoLite2 Database) for locating by IP. You can use geolcoator.setGeoIPSource() method to set a different Geo-IP source, but see the Caveats section before you do so.

    Caveats

    Mixed Content Restriction: There are alternative Geo-IP services to be used with this library. But most of these services do not provide a free API over HTTPS (SSL/TLS). You need to subscribe for a premium API key to use HTTPS. The caveat is; HTML5 Geolocation API is restricted to HTTPS and when you enable the fallbackToIP option, some browsers (such as Chrome and Firefox) will not allow mixed content. It will block HTTP content when the page is served over HTTPS.

    Currently, Geolocator will use nekudo/shiny_geoip by default which supports HTTPS. Please use this service responsibly and support Nekudo if you can.

    If you know other free Geo-IP services over HTTPS, let me know and we can add/use them as alternatives.

    Under the Hood

    Geolocator v2 is written in ES2015 (ES6), compiled with Babel, bundled with Webpack and documented with Docma.
