How to add translations to $translateProvider from outside the config?

Question

I am new to angular js. For language translation I am using angular-translate service in my work.I am getting the entire translations which I need to assign in $translateProvider by an API call response.I know that I can assign the translations to $translateprovider ($translateprovider.translations ('en',translations) only from config module but I think that an API call from config module is not a good practise.

Below given is my config module.

    .config(['$translateProvider', function($translateProvider) {

            //fetching session key
            var response;
            jQuery.ajax({
                type: "GET",
                url: 'https://abcdefg/session?appKey=123456',
                async: false,
               success: function(data) {
                   response = data;
                    getMetaData(response.sessionKey);

                }
            });

            ////fetching data.
            function getMetaData(sessionKey) {
                jQuery.ajax({
                    type: "GET",
                    url: 'https://abcdefg/metadata?sessionKey=' + sessionKey +
                        '&gid=1.2.3.4',
                    async: false,
                    success: function(data) {
                        dataSet = data; //save response in rootscope variable
                    }
                });
            }


            $translateProvider.translations('en_US', JSON.parse(dataSet.en_us));
            $translateProvider.translations('es_ES', JSON.parse(dataSet.es_es));
            $translateProvider.preferredLanguage('en_US');
}

How can this be solved? How can I assign translations to $translateProvider from out side the config module?

Thanks in advance.

Take a look at this answer from the creator of angular-translate , where he states that "[...]there's no way to extend existing translations during runtime with $translate service without using asynchronous loading.[...]"

For more information on asynchronous loading of translations take a look at the documentation . You may even specify your own custom loader to get translations by calling your API.

By many purposes, we may need to add more translations in Services, so I found a way to do that. We can create another CustomProvider which returns $translateProvider, and then we can inject CustomProvider to Services or Controllers.

// NOTE: Create another Provider returns $translateProvider
.provider('CustomProvider', function($translateProvider) {
  this.$get = function() {
    return $translateProvider;
  };
});

// NOTE: Inject CustomProvider to Service to use
.factory('TranslationService', function(CustomProvider) {

  console.log(CustomProvider);

  return {
    addMoreTranslations: addMoreTranslations
  };

  function addMoreTranslations(key, translations) {
    // Do somethings
    CustomProvider.translations(key, translations);
  }
});

I succeeded by that way.
