Passport-Naver

Passport strategies for authenticating with Naver using OAuth 2.0.

This module lets you authenticate using Naver in your Node.js applications. By plugging into Passport, Naver authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-naver

Usage of OAuth 2.0

Configure Strategy

The Naver OAuth 2.0 authentication strategy authenticates users using a Naver account and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a client ID, client secret, and callback URL.

var NaverStrategy = require('passport-naver').Strategy;

passport.use(new NaverStrategy({
        clientID: config.naver.clientID,
        clientSecret: config.naver.clientSecret,
        callbackURL: config.naver.callbackURL
	},
    function(accessToken, refreshToken, profile, done) {
        User.findOne({
            'naver.id': profile.id
        }, function(err, user) {
            if (!user) {
                user = new User({
                    name: profile.displayName,
                    email: profile.emails[0].value,
                    username: profile.displayName,
                    provider: 'naver',
                    naver: profile._json
                });
                user.save(function(err) {
                    if (err) console.log(err);
                    return done(err, user);
                });
            } else {
                return done(err, user);
            }
        });
    }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'naver' strategy, to authenticate requests.

For example, as route middleware in an Express application:

// Setting the naver oauth routes
app.route('/auth/naver')
    .get(passport.authenticate('naver', {
        failureRedirect: '#!/auth/login'
    }), users.signin);

// creates an account if no account of the new user
app.route('/auth/naver/callback')
    .get(passport.authenticate('naver', {
        failureRedirect: '#!/auth/login'
    }), users.createAccount, users.authCallback);

Re-authentication

Re-authentication is the act of asking a user to re-enter their Naver password whenever they sign in your service. This is useful to prevent man-in-the-middle hijacking while the user session of Naver is alive.

Here is an example that triggers re-authentication using an authType:

passport.use(new NaverStrategy({
        clientID: config.naver.clientID,
        clientSecret: config.naver.clientSecret,
        callbackURL: config.naver.callbackURL,
        svcType: 0,
        authType: 'reauthenticate'  // enable re-authentication
    },

App Registration for the Secret Generation

You need to register your application from Naver Developer Center. <Naver Developer Center>

You can get client id & secret for your application after the approval process of Naver Corp.

After the client id & secret are issued, assign them to the following variables.

        clientID: config.naver.clientID,
        clientSecret: config.naver.clientSecret,
        callbackURL: config.naver.callbackURL,

Examples

You can execute the following application from the 'examples' directory.

$ npm install 
$ node app.js

var express = require('express')
	, passport = require('passport')
	, session = require('express-session')
	, NaverStrategy = require('../lib/index.js').Strategy;
	
var client_id = '************ your app client id ************';
var client_secret = '************ your app client secret ************';
var callback_url = '************ your app callback url ************';

passport.serializeUser(function(user, done) {
	done(null, user);
});

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

passport.use(new NaverStrategy({
    clientID: client_id,
    clientSecret: client_secret,
    callbackURL: callback_url,
    svcType: 0  // optional. see http://gamedev.naver.com/index.php/%EC%98%A8%EB%9D%BC%EC%9D%B8%EA%B2%8C%EC%9E%84:OAuth_2.0_API
}, function(accessToken, refreshToken, profile, done) {
	process.nextTick(function () {
		//console.log("profile=");
		//console.log(profile);
		// data to be saved in DB
		user = {
			name: profile.displayName,
			email: profile.emails[0].value,
			username: profile.displayName,
			provider: 'naver',
			naver: profile._json
		};
		//console.log("user=");
		//console.log(user);
		return done(null, profile);
	});
}));

var app = express();

app.use(session({secret: 'keyboard cat'}));
app.use(passport.initialize());
app.use(passport.session());

app.set('view engine', 'jade');
app.set('views', __dirname + '/views/');

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

app.get('/account', ensureAuthenticated, function(req, res) {
	console.log(req.user);
	res.render('account', { user: req.user });
});

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

// Setting the naver oauth routes
app.get('/auth/naver', 
	passport.authenticate('naver', null), function(req, res) {
    	console.log('/auth/naver failed, stopped');
    });

// creates an account if no account of the new user
app.get('/auth/naver/callback', 
	passport.authenticate('naver', {
        failureRedirect: '#!/auth/login'
    }), function(req, res) {
    	res.redirect('/'); 
    });

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

app.listen(3000);

function ensureAuthenticated(req, res, next) {
	if (req.isAuthenticated()) { return next(); }
	res.redirect('/login');
}
