Instagram authentication with scopes permissions for Passport and Node.js.

instagram-auth.js

// Node.js module to define an ExpressJS subrouter that handles requests
// to /auth path and uses passport to login using Instagram OAuth 
var express = require('express');
var session = require('express-session');
var passport = require('passport');
var instagramStrategy = require('passport-instagram').Strategy;

// Require user model
var User = require('./user');

// Setup instagram strategy for passport
passport.use(new instagramStrategy({
		clientID: process.env.INSTAGRAM_CLIENT_ID,
		clientSecret: process.env.INSTAGRAM_CLIENT_SECRET,
		callbackURL: "http://localhost:3000/auth/instagram/callback"
	},
	function(accessToken, refreshToken, profile, done) {
		User.findOneAndUpdate(
			// query document
			{ instagramId: profile._json.data.id}, 
			// update-create document
			{
				username: profile._json.data.username,
				displayName: profile._json.data.full_name,
				picture: profile._json.data.profile_picture,
				instagramId: profile._json.data.id,
				instagramAccessToken: accessToken
			},
			// options
			{
				'new': true,
				upsert: true,
			},
			// callback
			function(err, user) {
				done(err, user);
			}
		);
	}
));

// Passport Serialization/Deserialization of user.id inside req object
passport.serializeUser(function(user, done) {
  done(null, user._id);
});

passport.deserializeUser(function(_id, done) {
  User.findById(_id, function(err, user) {
    done(err, user);
  });
});

// Configure Express router and middlewares (session and passport)
var auth = express.Router();
auth.use(session({
	secret: 'session secret',
	saveUninitialized: false,
	resave: false
}));
auth.use(passport.initialize());
auth.use(passport.session());


// Routes

// We can define the scope of token by provinding scope in the options object
auth.get('/instagram', passport.authenticate('instagram', { scope: ['basic', 'public_content', 'follower_list', 'comments', 'relationships', 'likes'] }));

auth.get('/instagram/callback', 
	passport.authenticate('instagram', {failureRedirect: '/fail'}), 
	function(req, res) {
		// Successful authentication, redirect home
		res.redirect('/auth/ok');
	});

// Verify user after auth
auth.get('/ok', function(req, res) {
	console.log(req.user);
	res.json({session: req.user});
});

module.exports = auth;

I wonder why this is not covered in official docs for passport instagram strategy.

Thanks for the gist

Unable to get email id from instagram. Is there anyother scope need to add to get email address?
