Freezing when signup using passport / express / mongodb - mongodb

Question

I'm working my way through a tutorial regarding passport.js and authentication and I'm coming unstuck. I'm just testing the signup function at the moment and my app is freezing. Here's my server file:
var express = require('express'),
app = express(),
mongoose = require('mongoose'),
passport = require('passport'),
flash = require('connect-flash'),
morgan = require('morgan'),
cookieParser = require('cookie-parser'),
bodyParser = require('body-parser'),
session = require('express-session');
// configDB = require('./config/database.js');
mongoose.connect('mongodb://localhost/Auth_practice');
require('./config/passport')(passport); // pass passport for config
// set up express app
app.use(morgan('dev')); // log every request to the console
app.use(cookieParser()); // read cookies (required for auth)
app.use(bodyParser()); // get information from html forms
app.set('view engine', 'ejs') // set up ejs for templating
// required for passport
app.use(session({secret: 'ilovethetoonandrafa'})); // session secret
app.use(passport.initialize());
app.use(passport.session()); // for persistent login
sessions
app.use(flash());
// routes
require('./app/routes.js')(app, passport); // load our routes
and pass in passport
app.listen(process.env.PORT, process.env.IP, function(){
console.log("Server has started")
});
Here's my user model:
// load the things we need
var mongoose = require('mongoose');
var bcrypt = require('bcrypt-nodejs');
// define schema for our user model
var userSchema = mongoose.Schema({
local :{
email : String,
password : String,
},
facebook :{
id : String,
token : String,
email : String,
name : String
},
twitter :{
id : String,
token : String,
displayName : String,
username : String
},
google :{
id : String,
token : String,
email : String,
name : String
}
});
// method =========================
// generate a hash
userSchema.methods.generateHash = function(password) {
return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};
// check if password is valid
userSchema.methods.validPassword = function(password) {
return bcrypt.compareSync(password, this.local.password);
};
// create the model for users and expose it to our app
module.exports = mongoose.model('User', userSchema);
My strategy setup:
// config/passport.js
// load all the things we need
var LocalStrategy = require('passport-local').Strategy;
// load up the user model
var User = require('../app/models/user');
// expose this function to our app using module.exports
module.exports = function(passport) {
// =========================================================================
// passport session setup ==================================================
// =========================================================================
// required for persistent login sessions
// passport needs ability to serialize and unserialize users out of session
// used to serialize the user for the session
passport.serializeUser(function(user, done) {
done(null, user.id);
});
// used to deserialize the user
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
// =========================================================================
// LOCAL SIGNUP ============================================================
// =========================================================================
// we are using named strategies since we have one for login and one for signup
// by default, if there was no name, it would just be called 'local'
passport.use('local-signup', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) {
// asynchronous
// User.findOne wont fire unless data is sent back
process.nextTick(function() {
// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists
User.findOne({ 'local.email' : email }, function(err, user) {
// if there are any errors, return the error
if (err)
return done(err);
// check to see if theres already a user with that email
if (user) {
return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
} else {
// if there is no user with that email
// create the user
var newUser = new User();
// set the user's local credentials
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
// save the user
newUser.save(function(err) {
if (err)
throw err;
return done(null, newUser);
});
}
});
});
}));
};
And my route for signup
app.post('/signup', passport.authenticate('local-signup', {
successRedirect: '/profile', // redirect to the secure profile of the
user
failureRedirect: '/signup', // redirect to signup page if failure
failureFlash: true // allow flash messages
}));
Finally here's the signup form:
<!-- views/signup.ejs -->
<!doctype html>
<html>
<head>
<title>Node Authentication</title>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.2/css/bootstrap.min.css"> <!-- load bootstrap css -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.min.css"> <!-- load fontawesome -->
<style>
body { padding-top:80px; }
</style>
</head>
<body>
<div class="container">
<div class="col-sm-6 col-sm-offset-3">
<h1><span class="fa fa-sign-in"></span> Signup</h1>
<!-- show any messages that come back with authentication -->
<% if (message.length > 0) { %>
<div class="alert alert-danger"><%= message %></div>
<% } %>
<!-- LOGIN FORM -->
<form action="/signup" method="post">
<div class="form-group">
<label>Email</label>
<input type="text" class="form-control" name="email">
</div>
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control" name="password">
</div>
<button type="submit" class="btn btn-warning btn-lg">Signup</button>
</form>
<hr>
<p>Already have an account? Login</p>
<p>Or go home.</p>
</div>
</div>
</body>
Can anyone see what's causing the app to freeze?
