Passport Not Authenticating Correctly - node.js

Question

This is my first time doing user authentication and I think I'm nearly complete. I'm using Express with Passport.js and MongoDB/Mongoose. When I run my gulp file everything loads correctly but when I attempt to login with my credentials I'm constantly redirected to the failure page (home screen). Here's my code:
// Initialize
const bodyParser = require('body-parser')
const path = require('path')
const bcrypt = require('bcryptjs')
const express = require('express')
const session = require('express-session')
const cookieParser = require('cookie-parser')
const passport = require('passport'),
LocalStrategy = require('passport-local').Strategy
let userData = require('./models/user.js')
const app = express()
// Configuration
app.use(cookieParser())
app.use(session({ secret: 'ThisIsTheSessionSecret', resave: true, saveUninitialized: true }))
app.use(passport.initialize())
app.use(passport.session())
app.use(express.static(path.join(__dirname, '../../docs')))
app.use(express.static(path.join(__dirname, '../../src')))
app.set('port', process.env.PORT || 8080);
app.set('view engine', 'pug')
app.set('views', 'src/pages')
let urlencodedParser = bodyParser.urlencoded({ extended: false })
// Configure authentication and sessions
passport.use(new LocalStrategy(
function(username, password, done) {
user.findOne({ username: username }, function(err, user) {
if (err) { console.log(err) }
if (!user) {
return done(null, false, { message: 'Incorrect username.' })
}
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' })
}
return done(null, user)
})
}
));
// Session
passport.serializeUser(function(user, done) {
done(null, user.id)
});
passport.deserializeUser(function(id, done) {
user.findById(id, function(err, user) {
done(err, user)
})
})
app.listen(app.get('port'))
console.log('Listening on port: ' + app.get('port'))
// Initialize database (local or remote?)
const MongoClient = require('mongodb').MongoClient,
mongoose = require('mongoose'),
assert = require('assert')
const database = 'mongodb://localhost:27017/database'
mongoose.connect(database)
let db = mongoose.connection
db.on('error', console.error.bind(console, 'connection error'))
db.once('open', function() {
// let testUser = new userData.UserModel({ username: 'PodcatchUser', password: 'RIPHarambe' })
// console.log(testUser.username)
})
// Routing
app.get('/', function(req, res) {
console.log('Welcome!')
res.render('index')
})
// Registration
app.post('/signup', urlencodedParser, function(req, res) {
let username = req.body.username,
password = req.body.password,
salt = bcrypt.genSaltSync(10),
hash = bcrypt.hashSync(password, salt)
let user = new userData.UserModel({
username: username,
password: hash
})
console.log(user.username)
console.log(user.password)
user.save(function(err) {
if (err) {
return console.log(err, user)
} else {
console.log('User has been saved to the database successfully')
}
})
res.end()
})
// Login
app.post('/login', passport.authenticate('local', { successRedirect: '/success',
failureRedirect: '/' }), function(req, res) {
res.end()
})
and the code in the userData module:
const mongoose = require('mongoose')
let UserSchema = mongoose.Schema({
username: String,
password: String
})
let UserModel = mongoose.model('UserModel', UserSchema)
module.exports.UserSchema = UserSchema
module.exports.UserModel = UserModel
I'm really confused as to what's happening. Mongo saves the credentials and hashed password to the database, I create a session and have a cookie parser but it doesn't authenticate. Help would be greatly appreciated :)
