In this mini-project, you will work with a group to add routes to an existing application. You will create one wildcard route for serving up a 404 page, as well as a diagnostics route for logging failed form validation.

How can we declare a wildcard route in Express.js?
How will fs.writeFile() help us log usage stats?
If you have completed this activity, work through the following challenge with your partner to further your knowledge:
