Full answer, including:

• Middleware to set redirectUrl
• Flash messages
• Not returning values that won't be used

Just create a redirectTo value in your loginRequired middleware:

var loginRequired = function(req, res, next) {
    if ( req.isAuthenticated() ) {
        next();
        return
    }
    // Redirect here if logged in successfully
    req.session.redirectTo = req.path;
    res.redirect('/login')
}

And then in your login POST:

router.post('/login', function(req, res, next) {
    passport.authenticate('local', function(err, user, info) {
        if ( err ) {
            next(err);
            return
        }
        // User does not exist
        if ( ! user ) {
            req.flash('error', 'Invalid email or password');
            res.redirect('/login');
            return
        }
        req.logIn(user, function(err) {
            // Invalid password
            if ( err ) {
                req.flash('error', 'Invalid email or password');
                next(err);
                return
            }
            res.redirect(req.session.redirectTo || '/orders');
            return
        });
    })(req, res, next);
});
