How to access variables set using app.set() in express js

Question

How do i access the variables set using express's app.set() for e.g

 app.set('view engine','jade'); app.set('jsDirectory',/js/');  

From the guide, i understand that i can access the same using app.get(<key>), but this is the output of console.log(app.get('view engine')).

 { router:    { app:       { stack: [Object],         domain: null,         _events: [Object],         _maxListeners: 10,         _connections: 0,         connections: [Getter/Setter],         allowHalfOpen: true,         _handle: null,         httpAllowHalfOpen: false,         cache: {},         settings: [Object],         redirects: {},         isCallbacks: {},         _locals: [Object],         dynamicViewHelpers: {},         errorHandlers: [],         route: '/',         routes: [Circular],         router: [Getter],         root: 'C:\\Users\\Shahal\\Works\\App',         models: {},         extensions: {},         disconnectSchemas: [Function: disconnectSchemas],         passport: [Object] },      routes: {},      params: {},      _params: [],      middleware: [Function] } }

They become available through the app.settings object:

app.set('oneSetting', 'one'); app.set('twoSetting', 'two'); app.set('view engine','jade');  console.log(app.settings.oneSetting); console.log(app.settings.twoSetting); console.log(app.settings['view engine']);
