Working with Routes

Applications would not exist without routes. Routes are the doors to those clients that need to consume your API. In this chapter, we will present more examples, focusing on how to become more proficient at managing routes and keeping track of all our endpoints. We will cover all the possibilities that Fastify offers to define new endpoints and manage the application without giving you a headache.

It is worth mentioning that Fastify supports async/await handlers out of the box, and it is crucial to understand its implications. You will look at the difference between sync and async handlers, and you will learn how to avoid the major pitfalls. Furthermore, we will learn how to handle URL parameters, the HTTP request’s body input, and query strings too.

Finally, you will understand how the router works in Fastify, and you will be able to control the routing to your application’s endpoint as never before.

In this chapter, we will cover the following...
