Hi!
I’m working on the (legacy) voting app, and I have issue with facebook authentication. Local Strategy worked fine.
My problem:
everything goes well, user is authenticated if already in db and created if not, I have a successRedirect, but no user in locals, so no effective logged in user even if it should be logged in…
and do you know what ‘#=’ means after a url?
If anyone can help me that would be so nice! I’m stuck!
here is my code:
my routes:
router.get('/auth/facebook', passport.authenticate('facebook'));
router.get('/auth/facebook/callback', userController.facebook);
my controller:
exports.facebook = passport.authenticate('facebook', {
failureRedirect: '/register',
successRedirect: '/',
});
my passport.js
passport.use(new FacebookStrategy({
clientID: process.env.FB_ID,
clientSecret: process.env.FB_SECRET,
callbackURL: `${process.env.APP_URL}${fbCb}`,
},
function(accessToken, refreshToken, profile, done) {
Auth.findOne({ 'facebook.id': profile.id }, (err, user) => {
if(err) {
console.log('error:' + err);
done(err);
}
if (user)
{
console.log('user exists: ' + user)
done(null, user);
}
else {
const facebookUser = new Auth({
'facebook.id': profile.id,
'facebook.token': accessToken,
'facebook.name': profile.displayName,
}).save(((err) => {
if(err ){
console.log('err: ' + err);
done(err);
}
done(null, facebookUser);
}));
}
});
}
));
passport.serializeUser((user, done) => {
done(null, user._id);
});
passport.deserializeUser((id, done) => {
Local.findById(id, (err, user) => {
done(err, user);
});
});
my app.js
const passport = require('passport');
const expressValidator = require('express-validator');
const routes = require('./routes/index');
require('./modules/passport');
(.....)
const app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');
app.use(express.static(path.join(__dirname, 'public')));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(expressValidator());
// impt! -> session
// allows us to store data on visitors from req to req
// keeps users logged in!!
app.use(session({
secret: process.env.SECRET,
resave: false,
saveUninitialized: false,
store: new MongoStore({ mongooseConnection: mongoose.connection }),
}));
// Configure passport middleware
app.use(passport.initialize());
app.use(passport.session());
// pass variables to templates and to requests!
app.use((req, res, next) => {
res.locals.h = helper;
res.locals.flashes = req.flash();
res.locals.user = req.user || null;
res.locals.currentPath = req.path;
next();
});
app.use('/', routes);
(.....)
hope this is readable 
What do I do wrong?
Thanks to anyone who could help or try!
