Do you know an option to make sockets with callbacks?

[daurnimator]

You would just make a new thread and do your callback from there:

cq:wrap(function()
    return mycallback(mysocket:read())
end)

[otgo]

I mean something like NodeJS: ex: c:send("text", callbackhere)

That is up to you to build on top of cqueues if you want it.
