  <pre><code>let session = require('express-session');
  let MySQLStore = require('express-mysql-session')(session);
  
  let db = require('./knexfile.js');
  let options = db[environment]['connection'];
  let sessionStore = new MySQLStore(options);
  
  app.use(session({
      secret: 'ecommerceSiteSecrets',
      cookie: {
          maxAge: 365 * 24 * 60 * 60 * 1000,
          expires: false
      },
      store: sessionStore,
      saveUninitialized: true,
      resave: true,
  }));
  </code></pre>

  <pre><code>Session {
    cookie:
     { path: '/',
       _expires: false,
       originalMaxAge: false,
