SharePoint site provider factory

config.js

.config(['spSiteProvider',function(spSiteProvider){
  
  spSiteProvider.siteSvcUrl('https://myspsite.com/_vti_bin/listdata.svc')
  
  
  }])

ngdSharePoint.js

angular.module('ngd.SharePoint',[])

.provider('spSite',['$injector',function spSiteProvider($injector){
    var siteSvcUrl;
    
    //this allows us to set the siteSvcUrl at an app level, in case we are only using one spSite
    //otherwise, instantiate the factory at a use-case level by passing the value to the spSite(svc) constructor and assigning the instance
    //to a variable for usage within context
    this.siteSvcUrl = function(url){
        siteSvcUrl = url;
        
    }
    
    this.$get = ['$http',function spSiteFactory($http){
        return $injector.instantiate(SpSite,{$http:$http,svc:siteSvcUrl})
        
    }]
}])


function SpSite(svc){
    var svcUrl = svc;
    
   return {
        getLists: function(){
            return $http.get(svcUrl);
        }, 
            
        getListData: function(list,query){
            var qry;
            if(query){
                qry = '?'+query;
            }
            return $http.get(svcUrl+'/'+list+qry);
            
        },
        create: function(data,query){
        
        },
        update: function(data,query){
        
        }
   
   }        

}

theCtrl.js

.controller('theCtrl',['$http','spSite',function($http,spSite){
    var splist = spSite.getListData('listA').then(function(data){
      
      //do something with data
      
    })  
  
  
}])

and tried adding as a prop on the SpSite function:

this.$inject = ['$http'];

Got it! took me long enough...
