AngularJS directive for the Leaflet Javascript Library. This software aims to easily embed maps managed by leaflet on your Leaflet project.

How to use it

You must include the leaflet-directive dependency on your angular module:

var app = angular.module("demoapp", ["leaflet-directive"]);

After that, you can change the default values of the directive (if you want) on your angular controller. For example, you can change the tiles source, the maxzoom on the leaflet map or the polyline path properties.

angular.extend($scope, {
    defaults: {
        tileLayer: "http://{s}.tile.opencyclemap.org/cycle/{z}/{x}/{y}.png",
        maxZoom: 14,
        path: {
            weight: 10,
            color: '#800000',
            opacity: 1
        }
    }
});

If you want to set the start of the map to a precise position, you can define the "center" property of the scope (lat, lng, zoom). It will be updated interacting on the scope and on the leaflet map in two-way binding. Example:

angular.extend($scope, {
    center: {
        lat: 51.505,
        lng: -0.09,
        zoom: 8
    }
});

If you need to run any method on the map object, use leafletData as following (notice the map object is returned in a form of a promise):

angular.module('myModule').controller('MapController', ['$scope', 'leafletData',
	function($scope, leafletData) {
	        leafletData.getMap().then(function(map) {
	            L.GeoIP.centerMapOnPosition(map, 15);
	        });
	}
]);

Finally, you must include the markup directive on your HTML page, like this:

<leaflet defaults="defaults" center="center" height="480px" width="640px"></leaflet>

If you want to have more than one map on the page and access their respective map objects, add an id attribute to your leaflet directive in HTML, like this:

<leaflet id="mymap" defaults="defaults" center="center" height="480px" width="640px"></leaflet>

And then you can use this id in getMap() like this:

angular.module('myModule').controller('MapController', ['$scope', 'leafletData',
	function($scope, leafletData) {
	        leafletData.getMap('mymap').then(function(map) {
	            L.GeoIP.centerMapOnPosition(map, 15);
	        });
	}
]);
