angularjs include another module in a service

Question

I want to include another module into my service, I have some constants / config related. My config module looks like:

angular.module('myApp.config', [])
  .constant('EnvironmentConfig', {
    "WindowsAzureADConfig": {
      "tenant": "aaa.onmicrosoft.com", 
      "clientAppId": "xx-xx-xx-xx-xx", 
      "authority": "https://login.windows.net/aa.onmicrosoft.com", 
      "resourceUrl": "https://graph.windows.net/", 
      "redirectUrl": "http://localhost:4400/services/aad/redirectTarget.html"
    }, 
    "AppEndPointConfig": {
      "tokenAccess": "aa-aa-a-a-aa", 
      "baseURL": "http://aa.aaa.aa/api/", 
      "paths": {
        "bpath": "bpath/"
      }
    }, 
    "PConfig": {
      "ApiKey": "aaadd2dasdasdas23f44ffsfsdf", 
      "printerId": 244312
    }
  }
);

I have the following angularjs service:

(function () {
  function MySrv(EnvironmentConfig) {
    var mySrv = {};
    var app = {
      aFunction: function () {
        console.log(EnvironmentConfig.authority); // getting undefined
      }
    };
    mySrv.app = app;

    return mySrv;
  }

  angular
    .module('myApp') // if adding .module('myApp', ['myApp.config']) then I'm getting a blank screen
    .service('MySrv', mySrv);
})();

Note that the module is included & defined before the service itself.

You need to add the dependecy where you declare the moduel. i.e .module('myApp', ['myApp.config']). Not in the service .js but where you first create the myApp-module — Gustav

You cannot re-declare a module, and you do that when you

.module('myApp', ['myApp.config'])

So as Gustav says, you either include the myApp.config where you declared the myApp the first time, or you put your service in a module of its own, like you did with the myApp.config.

.module('myApp.service', ['myApp.config'])

But then you need to include the service module into your myApp module. Like this:

.module('myApp', ['myApp.service'])

Since the service module includes the config module, you don't need to include it in the myApp module

authority is inside the object property WindowsAzureADConfig, so you need to update the log method.

refer below working code snippet with module dependency injection

angular.module('myApp.config', [])
    .constant('EnvironmentConfig', {"WindowsAzureADConfig":{"tenant":"aaa.onmicrosoft.com","clientAppId":"xx-xx-xx-xx-xx","authority":"https://login.windows.net/aa.onmicrosoft.com","resourceUrl":"https://graph.windows.net/","redirectUrl":"http://localhost:4400/services/aad/redirectTarget.html"},"AppEndPointConfig":{"tokenAccess":"aa-aa-a-a-aa","baseURL":"http://aa.aaa.aa/api/","paths":{"bpath":"bpath/"}},"PConfig":{"ApiKey":"aaadd2dasdasdas23f44ffsfsdf","printerId":244312}});



(function() {

      function MySrv(EnvironmentConfig) {

        var mySrv = {};

        var app = {
        aFunction: function() {
          console.log(EnvironmentConfig.WindowsAzureADConfig.authority); // authority is inside the object property WindowsAzureADConfig, so you need to update the log method
        }
        };

        mySrv.app = app;

        return mySrv;
        }

    angular
    .module('myApp',['myApp.config']) // this is the way to add dependency in module
    .controller('myController', function($scope, MySrv){
        $scope.aFunction = function(){
            MySrv.app.aFunction();
        }
    })
    .service('MySrv',MySrv)
    

    })();

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<div ng-controller="myController">
    <a ng-click="aFunction()">Click here</a>
</div>
</body>

Hope this Helps!
