+  const flash = require('express-flash');
+  const session = require('express-session');
+  const express = require('express');
+  const app = express();
+
+  // initialise session middleware - flash-express depends on it
+  app.use(session({
+    secret : "<add a secret string here>",
+    resave: false,
+    saveUninitialized: true
+  }));
+
+  // initialise the flash middleware
