index.js

    var express = require('express'); var multer = require("multer"); var router = express.router();   router.get('/', function(req, res) {   res.render('index.ejs', { title: 'express' }); });    module.exports = router; 

user.js (routes)

    var express = require('express'); var router = express.router(); var mongoose = require('mongoose'); var users = require("../models/users") /* users listing. */ router.get('/', function(req, res, next) {      console.log("inside function"); users.find(function(err, users){      res.send(users);   });  });  module.exports = router; 

user.js (models)

    var mongoose= require("mongoose"); var schema= mongoose.schema;  var usersschema = new schema({      username: string,     email: string,     password: string,     status: number });  mongoose.model("users",usersschema); 

newuser.js

    var express= require('express'); var router= express.router(); var mongoose = require(mongoose);  router.get('/', function(req, res) {      console.log("username : " + req.body.username+", email :  "+ req.body.email+ ", password :  " + req.body.password );  var newuser= users({      username: req.body.username,     email: req.body.email,     password: req.body.password,     status: '0'  });  newuser.save(function(err){ if(err) throw(err) var cryptr = require("./cryptr");     cryptr = new cryptr('mytotalysecretkey');     var encryptedstring = cryptr.encrypt(req.body.username);   var sendgrid  = require('sendgrid')("username", "password"); var email     = new sendgrid.email({   to:       req.body.email,   from:     'fromid',   subject:  'registration',   text:    "pls click on following link confirm https:/localhost:3000/confirmation?username="+ encryptedstring  }); sendgrid.send(email, function(err, json) {     if (err) { return console.error(err); }   console.log(json); });  res.send("ok");  }); });  

it simple, syntax error. typed in var mongoose = require(mongoose); instead of var mongoose = require("mongoose");my ide did not point out.

thank you
