/**
 * Builds the Express Router which is protected by a session auth
 *
 * Using the router requires you to install `express-session` as a

 * not optimized for production usage and, in development, it causes
 * logging out after every page refresh (if you use nodemon).

 * const ADMIN = {
 *   email: 'test@example.com',
