Hi Sven,
Why not simply:
(ZnServer startOn: 1337)
onRequestRespond: [:request |: ZnResponse ok: 'Hello world']
This is the closest form to that node.js example and really show the
power of Smalltalk and its closures. Also understandable to everyone
including the (IMHO) majority, who don't understand design patterns like
Delegate well.
Best regards
Janko
