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!
Accessing the route’s configuration

async function operation (request, reply) {

hello: 'world'
}
})
In this way, you can create...
