   Thank you for the suggestion 🙏🏻.

   I also use extensions similar to these in my own projects. As you have illustrated the difficulty is in choosing appropriate defaults for things like Date encoding and the status code to return.

   Hi @gotev I've been thinking a lot about your suggestion think there is a nice declarative solution SE-0389 Attached Macros available in Swift 5.9 and later.

   I'm interested in your feedback, the implementation is currently available on the branch preview/macro where handlers can annotate functions with routes:

   @HTTPHandler
   struct MyHandler {
   
     static let jsonTimestampMillisEncoder: JSONEncoder = {
       let jsonEncoder = JSONEncoder()
       jsonEncoder.dateEncodingStrategy = .millisecondsSince1970
       return jsonEncoder
     }()
   
     @JSONRoute("/cat", encoder: Self.jsonTimestampMillisEncoder)
     func getCat() -> Cat {
       Cat(birthDate: Date(), name: "Loris")
     }
   }
   
   let server = HTTPServer(port: 80, handler: MyHandler())
   try await server.start()

   The macro synthesises conformance to HTTPHandler delegating handling to the first matching route.
