If you compare all the Zn delegates that are included, such as Nick's
ZnDispatcherDelegate, I think it is clear that #handleRequest: is a good
interface. Different use cases require delegate's with more or less features
and thus complexity.
But for the sake of short/elegant examples, I added the
ZnSingleThreadedServer>>#onRequestRespond: convenience method, so the examples
now become:
(ZnServer startDefaultOn: 1337)
onRequestRespond: [ :request | ZnResponse ok: (ZnEntity text: 'Hello
World!') ].
and
(ZnServer startDefaultOn: 1337)
onRequestRespond: [ :request | ZnResponse ok: (ZnEntity with: request
contents) ].
