Adding new behaviors to routes

At the beginning of this chapter, we learned how to use the routeOptions object to configure a route, but we did not talk about the config option!

This simple field gives us the power to do the following:

• Access the config in the handler and hook functions
• Implement the Aspect-Oriented Programming (AOP) that we are going to see later

How does it work in practice? Let’s find out!
