Google maps for AngularJS

Posted on: August 12, 2014

Almost all web based projects, where location/address is included, we might require mapping service to show the exact location or street view on the page. Thanks to Google to give us such amazing service application, yes I am talking about Google Maps which offers street maps and street view perspective and many more. To get the map rendered in the web page using Angular JS is pretty easy and straight forward. I am going to show you how we can do this,

For this is so, I have created a directive so that I could reuse it throughout the application as an html tag. To locate the area, we might put its Latitude and Longitude or we might put just a valid address. The following directive could be used while we have the latitude and longitude for a particular area,

app.directive('areaBasedGoogleMap', function () {
    return {
        restrict: "A",
        template: "<div id='areaMap'></div>",
        scope: {           
            area: "=",
            zoom: "="
        controller: function ($scope) {
            var mapOptions;
            var map;           
            var marker;

            var initialize = function () {                                
                mapOptions = {
                    zoom: $scope.zoom,
                    center: new google.maps.LatLng(40.0000, -98.0000),
                    mapTypeId: google.maps.MapTypeId.TERRAIN
                map = new google.maps.Map
(document.getElementById('areaMap'), mapOptions); }; var createMarker = function (area) { var position = new google.maps.LatLng
(area.Latitude, area.Longitude); map.setCenter(position); marker = new google.maps.Marker({ map: map, position: position, title: area.Name }); }; $scope.$watch("area", function (area) { if (area != undefined) { createMarker(area); } }); initialize(); }, }; });

And this directive might be used while we have a valid address,

app.directive('addressBasedGoogleMap', function () {
    return {
        restrict: "A",
        template: "<div id='addressMap'></div>",
        scope: {
            address: "=",
            zoom: "="
        controller: function ($scope) {
            var geocoder;
            var latlng;
            var map;
            var marker;
            var initialize = function () {
                geocoder = new google.maps.Geocoder();
                latlng = new google.maps.LatLng(-34.397, 150.644);
                var mapOptions = {
                    zoom: $scope.zoom,
                    center: latlng,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                map = new google.maps.Map
(document.getElementById('addressMap'), mapOptions); }; var markAdressToMap = function () { geocoder.geocode({ 'address': $scope.address },
function (results, status)
{ if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } }); }; $scope.$watch("address", function () { if ($scope.address != undefined) { markAdressToMap(); } }); initialize(); }, }; });

And in html we can use these directives like the way,

<div address-based-google-map address="Adress" zoom="16"></div>
<div area-based-google-map area="Area" zoom="8"></div>

Finally Module and Controller definition,

var app = angular.module("Main_app", []);

app.controller("MainController", ["$scope", 
function MainController($scope) 
    $scope.Adress = "American University,4400 Massachusetts Ave NW,Washington, DC 20016";
    $scope.Area = { 
                    Name: "Melbourne", 
                    Latitude: -37.8140000, 
                    Longitude: 144.9633200 

One more thing, you need to include following JS file to your html page,


And the style,

 #areaMap, #addressMap
    height: 400px;
    width: 400px;
    margin: 10px;
    padding: 10px;

Very easy stuff but effective enough!!! Download Source Code

it’s very useful article…. i am so thankful to u..

but in development mode everything is fine.

but, in production mode.
iam getting this kind of error …

Error: [$injector:unpr] Unknown provider: tProvider <- t

when i commenting the directive, it's working fine without any errors.. but MAPS won't work with out the directive.. how to resolve the issue

This means that you missed to include the dependent modules. Can you check that you don’t have included any other modules related to the google maps and also check that you have include this JS file,


Very helpful article.. Thanks for the help.. But can you please help with the directions?
