socket.io

Hello,

I am considering Amber as one of the choices for making client in a suite of client-server applications. The choice of client-server communication was socket.io. Is it possible to use socket.io from amber (I know it is possible to use other js libs, but is it easy to use callbacks in them, like convert block to closure or so?)?

Thanx, Herby

Hi,

A block closure *is* a callback in JavaScript. By that I mean that it is
the same object.

anObject.on('hello', function(e) {...})

and:

anObject on: 'foo' do: [:e | ... ]

are strictly equivalent.

HTH,

Wow! That's cool and helpful :) Is this part of the documentation? Luckily I stumbled upon this post...

Yes, it is there:
