OAuth (Passport.js) Tutorial #18 - Redirecting Users

Hey gang, in this OAuth tutorial I'll show you how we can redirect users based on their login status. For example, if a page requires authenication and a user is not logged in, we'll redirect them to the login page.

It's crazy. I looked at a ton of tutorials around the web and every single one of them is either uncomplete, assuming stuff, mixed up, and just doing stuff not right.

Now I binged through this series and it all just clicked. just like that. Finally got my head around passport.

THANK YOU !

The order of middleware loading is important: middleware functions that are loaded first are also executed first.
In my case it was the order of cookiesession and passport

app.use(cookieSession({
maxAge: 24 * 60 * 60 * 1000,

}))


app.use(passport.session());

When passport block is front of cookiesession it throw error undefined.

Thanks for the lessons Ninja, your a life saver.. literally your saving me tons of time of my life..

For anybody getting the username undefined error, check the order of the middleware. For me i needed to usue cookie sessions before registering passport.initialize() and passport.session()

Same here after redirecting req.user is showing undefined.
How to fix this??

[saurabhshubham]

res.send('You are logged in, this is your profile ' + req.user.username);

req.user.username is sending 'undefined'

[devinzimmerman]

To fix my undefined error, I didn't put the secret key inside of [] which would cause the deserializeUser to not call.

[avichalchadha]

For all those who are receiving undefined error, scroll down you will see many solution. Also do not that in
app.use(Cookiesession({

maxAge:24*60,
keys:['euhftcycidjdnsns']

}));

KEYS ARE ARRAY

my if(!req.user) keeps kicking to my login page no matter how many times I log in. also from the auth routes, i keep getting [object Object] when I try and inspect the object.

[tusharsoni]

req.user is undefined, someone help? in deployment im getting this issue but not in local

[kodieivie]

I just had a funky bug.. n i spent a few hours on it.. everything was good at google/redirect route but then when i used res.redirect i couldn't get anything from req.user.username at my new route.. like it dropped from the request object.. i spent hours going over everything, trying anything out.. it wasnt working. then i decided to try res.send('your logged in as ' + req.user); {{<---without the .username}} i got the object back then i tried it normal again{{ res.send('your logged in as ' + req.user.username);}} and it worked..? so then i hit cmd + z twice and try it again like it was and its still works.. i jus dont get what was wrong? i tried for hours to figure this out. i erased the sites cookies.. could it have been the browser cache? it makes no sense i even chose out new routes. logged each step to the console. even a different google account. you would think something was misspelled but thats why i checked with the undo.. atleast im more familiar with passport now.. it just bugs me that i dont know what was wrong..

[vitaliishapoval]

Almost everybody has error: "req.user.username is undefined" when redirects to profile page. Just try to change your deserializeUser function to this:

passport.deserializeUser((id, done) => {
User.findById(id, (err, user) => {

if (err) {
throw err;
}

console.log('deserializing user', id);
done(null, user);
});
});

Hope it helps someone.
