my server side code given below.

server.js

var port=8888; var express=require('express'); var http=require('http'); var morgan         = require('morgan'); var bodyparser     = require('body-parser'); var methodoverride = require('method-override'); var cookieparser     = require('cookie-parser'); var session = require('express-session'); var mongodbstore = require('connect-mongodb-session')(session); var mongo = require('mongojs'); var app=express(); var server=http.createserver(app); db = 'doctor', collections = ['oditek'], db = mongo.connect("127.0.0.1:27017/"+db, collections); app.use(express.static(__dirname + '/public'));     // set static files location /public/img /img users app.use(morgan('dev'));                     // log every request console app.use(bodyparser.urlencoded({ extended: false }))    // parse application/x-www-form-urlencoded app.use(bodyparser.json())    // parse application/json app.use(methodoverride()); app.use(cookieparser()); //app.use(expresssession({secret:'somesecrettokenhere'}));                  // simulate delete , put app.get('/',function(req,res){     res.sendfile('view/index.html'); }) app.get('/login',function(req,res){     res.sendfile('view/login.html'); }); app.get('/chatroom',function(req,res){     if(req.session){         res.sendfile('view/chatroom.html');     } }); server.listen(port); console.log('server running on port'+port);

here requirement if user logged in client side chatroom.html page , if not in client side ask login.i implementing here connect-mongodb-session store session.i have read posts regarding , tried answer still error there.please me resolve error.

since you're using mongojs module, you're going have connect database using following method

db = mongo("127.0.0.1:27017/"+db, collections);
