This chapter has explained how routing works in Fastify, from route definition to request evaluation.
Now, you know how to add new endpoints and implement an effective handler function, both async or sync, with all the different aspects that might impact the request flow. You know how to access the client’s input to accomplish your business logic and reply effectively with a success or an error.
We saw how the server context could impact the route handler implementation, executing the hooks in that encapsulated context and accessing the decorators registered. Moreover, you learned how to tweak the route initialization by using the
onRoute hook and the route’s
config: using Fastify’s features together gives us new ways to build software even more quickly!
The routing has no more secrets for you, and you can define a complete set of flexible routes to evolve thanks to the constraints and manage a broad set of real-world use cases to get things done...
