Cannot set a route in my Node.js Express.js application -

i have node.js application , using express.js framework well. dir structure following:

myapp   +-- node_modules   +-- public   +-- routes          |-- index.js          |-- mynewpage.js   +-- views          |-- index.ejs          |-- mynewpage.ejs   |-- app.js   |-- package.json 

the app.js file this:

 2  /**  3   * module dependencies.  4   */  5    6  var express = require('express')  7    , routes = require('./routes')  9    , http = require('http') 10    , path = require('path'); 11   12  var app = express(); 13   14  // environments 15  app.set('port', process.env.port || 3000); 16  app.set('views', __dirname + '/views'); 17  app.set('view engine', 'ejs'); 18  app.use(express.favicon()); 19  app.use(express.logger('dev')); 20  app.use(express.bodyparser()); 21  app.use(express.methodoverride()); 22  app.use(express.cookieparser('your secret here')); 23  app.use(express.session()); 24  app.use(app.router); 25  app.use(require('less-middleware')({ src: __dirname + '/public' })); 26  app.use(express.static(path.join(__dirname, 'public'))); 27   28  // development 29  if ('development' == app.get('env')) { 30    app.use(express.errorhandler()); 31  } 32   33  app.get('/', routes.index); 35  app.get('/mynewpage', routes.mynewpage); /* line */ 36   37  http.createserver(app).listen(app.get('port'), function(){ 38    console.log('express server listening on port ' + app.get('port')); 39  }); 

file mynewpage.js follows:

exports.mynewpage = function(req, res){   res.render('mynewpage', { title: 'hello' }, function(err, html) {}); }; 

when try: node app.js line marked uncommented, error:

/home/myuser/www/app-www/node_modules/express/lib/router/index.js:252 throw new error(msg); ^ error: .get() requires callback functions got [object undefined] @ /home/myuser/www/app-www/node_modules/express/lib/router/index.js:252:11 @ array.foreach (native) @ router.route (/home/myuser/www/app-www/node_modules/express/lib/router/index.js:248:13) @ router.(anonymous function) [as get] (/home/myuser/www/app-www/node_modules/express/lib/router/index.js:270:16) @ function.app.(anonymous function) [as get] (/home/myuser/www/app-www/node_modules/express/lib/application.js:413:26) @ object.

if uncomment line, goes well. what's problem? thankyou

you placed exports.mynewpage mynewpage.js file, not referencing anywhere, , trying use routes object.
while you've called required ./routes load index.js, not files folder.

just put code callback routes.js , work.
