Reading properties file value in Angular

I have gone through a few replies about using $http service for accessing the properties file, but now sure how it would fit in this scenario I have created a service that returns the hostnames from the poperties file, the calling client to this service should make a blocking call to the service and proceed only if the property file is read.

var serviceMod = angular.module('serviceModule',[])
.factory('configService', function($http){
    return {
        getValue: function(key){
            $http.get("js/resources/urls.properties").success(function(response){

                console.log('how to send this response to clients sync??? ' + response)

            })
            return ????

        }
    }
})

someOtherControllr.js

var urlValue = configService.getValue('url')

The problem I am facing is to do with the aync nature of the $http service. By the time the response is received by the callback, the main thread is already finished executing the someOtherController.js

You need to resolve the promise returned by the service. We can just return the $http call and resolve it in our controller (since return $http.get be a promise itself). Check out the AngularJS $q and $http docs for a bettering understanding of the underlying mechanics going on, and observe the following change...

.factory('configService', function($http) {
    return {
        getValue: function(key) {
            return $http.get('js/resources/urls.properties');
        }
    }
});

var urlValue;

// --asynchronous
configService.getValue('url').then(function(response) {
    urlValue = response.data; // -- success logic
});

console.log('be mindful - I will execute before you get a response');

Simple way - use callback (it will still be async. In fact you cant make it sync) :

    getValue: function(key, onSuccess){
        $http.get("js/resources/urls.properties").success(function(response){
            onSuccess(response);
   })
