-## 5 Extension Tasks

-Congratulations, you now have a working secure website shell which can be used as the base code for your coursework. You should now consider the following:
-
-1. Start by encrypting your cookies using an appropriate npm package.
-2. The website is currently using a relational database (SQLite). If you plan on using a different form of persistence such as a document database (eg MongoDB) or a graph database (eg Neo4J) this is the time to make the change. Make sure the existing functionality works with your chosen persistence technology.
-3. In your last lab you learned how to build list and details pages and connect these together. Read your assignment brief carefully and decide if and how you will implement these. You should start work on this part of your project at the earliest opportunity.
-4. You will need to implement one or more forms as part of your assignment. Analyse the problem and build template files containing your required forms. Also implement the code required to process this data and add it to your preferred database.
+7. Modify the secure page so that it displays the username of the currently logged-in user:
+    1. Start by modifying the `post('login')` callback, adding a second key called `username` to the `ctx.session` object to store the username.
+    2. Modify the code that logs the user out to remove this key.
+    3. Now change the callback for the secure home page so that it sends this data to the handlebars template.
+    4. Finally create a placeholder in the template to display this information.
