You can add this export:

module.exports = function flash(req, res, next) {
  if (!req.session.flash) {
    req.session.flash = {};
    req.session.flash['success'] = [];
    req.session.flash['warning'] = [];
  }
  next();
};

and then in the view:

<% if (req.session.flash['success'].length > 0) { %>

  <%= req.session.flash['success'].pop() %>

<% } %>
<% if (req.session.flash['warning'].length > 0) { %>

  <%= req.session.flash['warning'].pop() %>

<% } %>

You can create messages in the controller like this:

req.session.flash['success'].push('Updated successfully');
