Node Authentication w/Passport.js

Dependencies

npm install the following with --save:

• passport
• passport-local
• passport-local-mongoose
• express-session

Setup Passport in app.js

var mongoose = require('mongoose');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

Sessions

Now, let's configure sessions and Passport:

app.use(require('express-session')({
    secret: 'roger panella unicorn man',
    resave: false,
    saveUninitialized: false
}));
app.use(passport.initialize());
app.use(passport.session());

Model

Next, let's build our model:

// account model
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var passportLocalMongoose = require('passport-local-mongoose');

var Account = new Schema({
    username: String,
    password: String
});

Account.plugin(passportLocalMongoose);

module.exports = mongoose.model('Account', Account);

Controller

And finally, our controller:

//account controller
var express = require('express');
var passport = require('passport');
var Account = require('../models/Account');
var router = express.Router();

router.get('/', function (req, res) {
    res.render('index', { user : req.user });
});

router.get('/register', function(req, res) {
    res.render('register', { });
});

router.post('/register', function(req, res) {
    Account.register(new Account({ username : req.body.username }), req.body.password, function(err, account) {
        if (err) {
            return res.render('register', { account : account });
        }

        passport.authenticate('local')(req, res, function () {
            res.redirect('/');
        });
    });
});

router.get('/login', function(req, res) {
    res.render('login', { user : req.user });
});

router.post('/login', passport.authenticate('local'), function(req, res) {
    res.redirect('/');
});

router.get('/logout', function(req, res) {
    req.logout();
    res.redirect('/');
});

router.get('/ping', function(req, res){
    res.status(200).send("pong!");
});

module.exports = router;
