You haven't set isLoggedIn before using it, so it is still undefined at that point.

Move this:

isLoggedIn = function(req, res, next) {
  if (req.isAuthenticated()) {
    return next();
  }
  return res.redirect('/');
};

before this line:

router.get('/editor', isLoggedIn, function(req, res) {

Or get rid of the isLoggedIn variable and use function isLoggedIn() {} syntax to have the function hoisted:

function isLoggedIn(req, res, next) {
  if (req.isAuthenticated()) {
    return next();
  }
  return res.redirect('/');
};
