AngularGeoFire

Angular service wrapping the GeoFire geospatial lib for Firebase.

Usage

bower install angularGeoFire

In your app, include the Firebase and GeoFire libraries (technically AngularGeoFire doesn't depend on AngularFire but you'll probably want to use it).

<script src="bower_components/firebase/dist/firebase.js"></script>
<script src="bower_components/rsvp/rsvp.js"></script>
<script src="bower_components/angularfire/angularfire.js"></script>
<script src="bower_components/geofire/dist/geofire.js"></script>
<script src="bower_components/AngularGeoFire/dist/angularGeoFire.js"></script>

Include angularGeoFire.min.js and then include it in your app dependency. The API matches that of geoFire @ https://github.com/firebase/geoFire, just prefix the method calls with a $ (ex: $geoFire.$set). AngularGeoFire translates GeoFire's RSVP promises into Angular $q service promises. The GeoFire "on" events are translated into Angular broadcasts to be consumed anywhere in your app.

angular.module('yourApp', ['angularGeoFire']);

Then you can reference the dependency in your services or controllers

angular.module('yourApp')
  .controller('SomeCtrl', function($scope, $geofire, $log) {
    $scope.searchResults = [];

    var $geo = $geofire(new Firebase('https://<<your-firebase>>.firebaseio.com/'));

    // Trivial example of inserting some data and querying data
    $geo.$set("some_key", [37.771393,-122.447104])
        .catch(function(err) {
            $log.error(err);
        });

    // Get some_key's location, place it on $scope
    $geo.$get("some_key")
        .then(function (location) {
            $scope.objLocation = location;
        });

    // Remove "some_key" location from forge
    $geo.$remove("some_key")
        .catch(function (err) {
            $log.error(err);
        });


    // Setup a GeoQuery
    var query = $geo.$query({
        center: [37.77, -122.447],
        radius: 20
    });

    // Setup Angular Broadcast event for when an object enters our query
    var geoQueryCallback = query.on("key_entered", "SEARCH:KEY_ENTERED");

    // Listen for Angular Broadcast
    $scope.$on("SEARCH:KEY_ENTERED", function (event, key, location, distance) {
        // Do something interesting with object
        $scope.searchResults.push({key: key, location: location, distance: distance});

        // Cancel the query if the distance is > 5 km
        if(distance > 5) {
            geoQueryCallback.cancel();
        }
    });

    // See geofire documentation for other on("..") events available







  });
