Error: passport.initialize() middleware not in use what order to make calls?

Question

I have the follow - Generated initially by the Visual Studio Node Tools, uses Express and Jade as the client

/**
 * Module dependencies.
 */

var express         = require('express');
var fs              = require('fs');
var routes          = require('./routes');
var user            = require('./routes/user');
var http            = require('http');
var https           = require('https');
var path            = require('path');
var passport        = require('passport');
var googleStrategy  = require('passport-google-oauth').OAuth2Strategy;
var loginHandler    = require('./routes/Login.js');
var auth            = require('./config/auth.js');
var googleSupport   = require('./googleSupport.js');

var googleAuthority = auth.googleAuth;
var googleScopes = '';


// retrieve google scopes
googleScopes = googleSupport.discoverServiceScopes(auth.googleAuth);

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

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

passport.use(new googleStrategy({
    clientID: googleAuthority.clientId,
    clientSecret: googleAuthority.clientSecret,
    callbackURL: googleAuthority.callbackUrl
},
function (accessToken, refreshToken, profile, done) {
    return done(null, profile);
}
));
var request = require('request');

var app = express();

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

// development only
if ('development' == app.get('env')) {
    app.use(express.errorHandler());
}

console.log('extracting service scopes');

app.get(passport.initialize());
app.get(passport.session());

app.get('/', routes.index);
app.get('/index', routes.index);

// google login support

// go to login page.
app.get('/googleLogin', passport.authenticate('google', { scope: [googleScopes] }), 
    function (req, res) {
        res.redirect('/');
    }
);

app.get('/AuthorizeGoogle', passport.authenticate('google', { failureRedirect: '/'}), 
    function (req, res) { 
        res.redirect('/');
    });


http.createServer(app).listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

The thing is when it validates the user I get the following

500 Error: passport.initialize() middleware not in use

Now I am assuming this is the same cause as this question passport.js passport.initialize() middleware not in use but cannot see what order the calls should be in my code.

So can anyone tell me what order to place the various parts of the code.

Thanks

Answer 1

Try changing this part

app.get(passport.initialize());
app.get(passport.session());

to

app.use(passport.initialize());
app.use(passport.session());

further reading on subject : Difference between app.use and app.get in express.js , and I would suggest you separate passport configuration in a stand alone file and require it on paths that need authentication.
