jquery - Backbone Router doesn't appear to correctly Extending Router -

define([  'jquery',  'underscore',  'backbone',   'app',   'models/sessionmodel',   'views/home/homeview',  ], function(     $,     _,     backbone,     app,     sessionmodel,     homeview ){   approuter = backbone.router.extend({       initialize: function(options){},       routes : {        ''            :'showhome',      },      showhome : function(){       this.show(new homeview());     },       });      return approuter;  }); 

and here main first hit per backbone standards. have file called app created empty object , returns it...

require.config({ paths: { jquery: 'libs/jquery/jquery-1.8.2', underscore: 'libs/underscore/underscore-min', backbone: 'libs/backbone/backbone-1.0.0-min', text: 'libs/require/text', router: 'router', app: 'app' }, shim: {     jquery: {         exports: '$'     },     underscore: {         exports: '_'     },     backbone: {         deps: ["underscore", "jquery"],         exports: "backbone"     } } });  require(['app','router', 'models/sessionmodel'], function(app, approuter, sessionmodel) {      app.router = new approuter();     app.session = new sessionmodel();     app.session.checkauth({          complete: function(){             backbone.history.start();         }     }); }); 

when console log this, router missing default methods (specifically navigate, in addition others on, off, trigger, etc.).

it seems don't check __proto__ property of logged object:
