How to use constant module in angular?

In my angular application I have a settings module that I made a constant. I figured that it should be a constant because the constants get applied before other provide methods.

I also have 2 services: getUserIdService and getTokenService that get me userId and token respectively. 

angular.module('app').constant('settings', {
    streamServer: 'http://someurl.com:9009',
    userId: /* $getUserIdService.getUserId() */
    token: /* $getTokenService.getToken() */
});

From what I see in the api constant doesn't have a constructor so I can't pass in any dependencies (getUserIdService, getTokenService)

This module needs to be globally available and it doesn't have to be a constant. I just need it to get initialized before any other module.

How can I do this?

Use the angular module run method to initialize your data. You can inject your services into the run method and use it to initialize your data

Sample demo: http://plnkr.co/edit/TW5r7YM5gkevWr2hjmZs?p=preview

JS:

var app = angular.module('plunker', []);

app.value('settings', {
    streamServer: 'http://someurl.com:9009',
    userId:null ,/* $getUserIdService.getUserId() */
    token: null/* $getTokenService.getToken() */
}).run(function($http,$timeout,settings){//inject your services here
  settings.userId = 'guru';//call services to get the user id
  settings.token = 'tkn39';
});
