// ================================================================

// Passport session setup.
//   To support persistent login sessions, Passport needs to be able to
//   serialize users into and deserialize users out of the session.  Typically,
//   this will be as simple as storing the user ID when serializing, and finding
//   the user by ID when deserializing.  However, since this example does not
//   have a database of user records, the complete Facebook profile is serialized
//   and deserialized.
passport.serializeUser(function(user, done) {
	done(null, user);
});

passport.deserializeUser(function(obj, done) {
	done(null, obj);
});

// Use the FacebookStrategy within Passport.
//   Strategies in Passport require a `verify` function, which accept
//   credentials (in this case, an accessToken, refreshToken, and Facebook
//   profile), and invoke a callback with a user object.
passport.use(new FacebookStrategy({
		clientID: process.env.FACEBOOK_APP_ID,
		clientSecret: process.env.FACEBOOK_APP_SECRET,
		callbackURL: process.env.FACEBOOK_CALLBACK_URL,
		enableProof: false
	},
	function(accessToken, refreshToken, profile, done) {
		console.log(profile);
		return done(null, profile);
		// @todo to create our own user
		//User.findOrCreate({ facebookId: profile.id }, function (err, user) {
		//	return done(err, user);
		//});
