MongoDB CRUD the MVC way with Passport Authentication 65
1 passport = require('./config/passport');
2 ...
3 var passport = passport();
Also, require it in the config/express.js file like this:
1 passport = require('passport');
2
3 //use this code before any route definitions
4 app.use(passport.initialize());
5 app.use(passport.session());
Now you need to install at least one authentication strategy, and here I’ll show you three: local
strategy (username/password) authentication, Facebook OAuth authentication and Twitter OAuth
authentication with exact steps.
Local authentication strategy
First, install the local strategy authentication module:
1 $ npm install passport-local --save
Now, in the config folder, create a new folder called strategies and a new file local.js with the
following code:
1 var passport = require('passport'),
2 LocalStrategy = require('passport-local').Strategy,
3 User = require('mongoose').model('User');
4
5 module.exports = function() {
6 passport.use(new LocalStrategy(function(username, password, done) {
7 User.findOne(
8 {username: username},
9 function(err, user) {
10 if (err) {
11 return done(err);
12 }
13
14 if (!user) {
15 return done(null, false, {message: 'Unknown user'});
16 }
