Twitter Oauth Node.js Express console.log not showing

I am using the following code to implmenet twitter Oauth in node.js. The token and tokenSecret are not showing up in the console.
Everything else is working correctly, like the login, authentication, and callback functions.
All I see in the console are the access logs like the following:
GET / 304 197.320 ms - -
GET /stylesheets/style.css 304 2.092 ms - -
GET /auth/twitter 302 404.252 ms - 0
All I want to do is show the access token and access secret of the authenticated user.

app.use(session({

}));
app.use(passport.initialize());
app.use(passport.session());
// passport-twitter settings
passport.use(new TwitterStrategy({
consumerKey: config.consumerKey,
consumerSecret: config.consumerSecret,
callbackURL: config.callbackURL
},
// After authentication
function(token, tokenSecret, profile, done) {
console.log("token: " + token);
console.log("tokenSecret: " + tokenSecret);
return done(null, profile);
}
));
// Save to session
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(user, done) {
done(null, user);
});
app.use('/', indexRouter);
app.use('/success', usersRouter);
app.get('/auth/twitter', passport.authenticate('twitter'));
app.get('/auth/twitter/callback',
passport.authenticate('twitter', { failureRedirect: '/?auth_failed' }),
function (req, res) {
res.redirect('/success');
});
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;

I set the callback url in the twitter app page to "http://localhost:3000/auth/twitter/callback" and it worked.

How to access app.locals variable in handlebars

});

var signup = require('./routes/signup');
var login = require('./routes/login');
var adreqform =

var app = express();

app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({

}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname,
'public')));
app.use(session({
secret: 'gh jewellery',
resave: true,
saveUninitialized: false
}));
app.use(function(req, res, next) {
app.locals.currentUser = req.session.user;
next();
});
app.use('/', index);
app.use('/users', users);
app.use('/dashboard',
dashboard);
app.use('/signup', signup);
app.use('/login', login);
app.use('/adreqform', adreqform);
// catch 404 and forward to error handler app.use(function (req, res,
next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler // will print stacktrace if
(app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler // no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
app.set('port', process.env.PORT || 3000);
module.exports = app;
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});
Notice I assign app.locals.currentUser = req.session.user; above and req.session.user gets set when my route /login is hit and here is it's code.
login.js
var express = require('express');
var router = express.Router();
var User = require('../models/user.model.js');
var app = require('../app');
/* GET signup page. */
router.get('/', function(req, res, next) {
res.render('login');
});
router.post('/', function(req, res, next) {
User.findOne({
email: req.body.email
}, function(err, user) {
var logged = false;
if (err) {
console.log(err);
} else if (!user) {
res.render('login', {
errnoacc: 'User does not exist! Please register.'
})
} else if (user && req.body.password == user.password) {
req.session.user = user;
res.render('dashboard');
} else {
res.render('login', {
errpass: 'Password does not match. Please try again!'
});
}
});
next();
});
module.exports = router;
In the above code when POST is hit, I assign req.session.user = user; if all is good I render the dashboard view, there are a layout.hbs which has navbar where I want to use app.locals.currentUser to show currentUser object.
Using in my layouts.hbs {{currentUser.username}} doesn't work.
I am new to expressjs development so I know I am missing something.

app.locals holds settings for all application, if you app gets more than one user it will overwrite the information.
app.use(function(req, res, next) {
app.locals.currentUser = req.session.user;
next();
});
You may use res.locals:
app.use(function(req, res, next){
res.locals.user = req.user;
res.locals.authenticated = ! req.user.anonymous;
next();
});
Then you can access in handlebar like:
p #{user.userName}

Passport Unknown authentication strategy

I am following this tutorial on creating an authentication system with passport in Nodejs
Currently I am trying to make the signup form work, but it gives this error:
Error: Unknown authentication strategy "local-signup"

I am pretty sure that the config/passport.js file isn't seen by the routes/users.js file, but as I am a beginner I can't seem to find a solution to my problem.

config/password.js exports a function but you never call this function. In app.js, you should have something like that :
require('./config/passport')(passport);

)You have to set the routes with passport after the app.use() methods and send passport as argument. so:
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
var passport = require('passport');
var flash = require('connect-flash');
var morgan = require('morgan');
var session = require('express-session');
var configDB = require('./config/database.js');
mongoose.connect(configDB.url);
require('./config/passport');
// init app
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(morgan('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
app.use(session({ secret: 'godaddy420' })); // session secret
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
app.use(function (req, res, next) {
res.locals.path = req.path;
next();
});
// require('./app/routes.js')(app, passport); // load our routes and pass in our app and fully configured passport
var index = require('./routes/index')(app, passport);
var users = require('./routes/users')(app, passport);
app.use('/', index);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
Inside 'index' and 'users' use the passport that you are sending as argument.

Undefined while sending post nodejs

I try to send a form with data in my nodejs app but I get "undefined" I am not sure does it matter but in console first I see "undefined", then POST. I have tried some "fixes" from the Internet like adding "type:'application/*+json', inflate: false" to app.use(bodyParser.json...) but nothing worked for me...
Undefined
POST /users/register 200 32.777 ms - 2346
this is my routes/users.js file:
var express = require('express');
var router = express.Router();
router.get('/register', function(req, res, next) {
res.render('register', {

Routing works fine what show setting up a title to "Register", but I have problems with sending post :/

You're configuring body-parser to only accept JSON request bodies, but your form is submitted in URL-encoded format (application/x-www-form-urlencoded).
For that, you need to add the correct parser:
app.use(bodyParser.urlencoded({ extended : true }));
More information, also on the meaning of extended : true, here.

Why is my server returning error 500 while trying to set a cookie?

I have an express v4 server with a route called admin. When the user post a password to the admin route, I want to respond by setting a cookie on the user's browser and sending a small json. For some reason, the server keeps returning error 500 when trying to respond. I'm assuming that this is something to do with the cookie as I can do "res.send()" without any problem. I'm new to express/nodejs so any help is appreciated.

var router = express.Router();
var cookieParser = require('cookie-parser');

Dumb mistake: Cookie should have been 'cookie'...
