Where does userId come from?

Hi, in the profile route where does in 'req.session.userId' where does userId come from?

router.get('/profile', (req, res, next) => {
  if (!req.session.userId) {
    const err = new Error('Not allowed');
    err.status = 403;
    return next(err);
  }
  User.findById(req.session.userId)
    .exec(function (error, user) {
      if (error) {
        return next(error);
      }else{
        return res.render('profile', {title: 'Profile', name: user.name, favorite: user.favoriteBook })
      }
    })
});

The req.session.userId is set when a user signs up or when a user logs into the app. You are basically taking the id property from the user and setting it as a property on req.session. See example below:

router.post('/login', (req, res, next) => {
    User.login(req.body.email, req.body.password, (err, foundUser) => {
        if(err || !foundUser) {
            const err = new Error('User not found.');
            next(err);
        } else if(foundUser) {
            req.session.userId = foundUser.id;
            res.redirect('profile');
        }
    });
});

Thanks so much for the response, so basically it's a variable?

It's more of a property on a session object like this:

req: {
    session: {
        userId: "acbd1234"
    }
}

If you found my answer useful, please mark it as the accepted answer, thanks!
