callbex

asynchronous callback extras and shortcuts for coffeescript / javascript

Callbacks:

Concept

Call a function with signiture: my_fn(arguments..., callback_fn) Function returns asynchronous response by calling callback_fn with signiture: callback_fn(err, response_arguments...) in which err is null or undefined unless an error-response is returned.

Example

my_fn arg1, arg2, (err, response_arg1, response_arg2) ->
  if err
    # error path
  else
    next_async_fn arg_x, (err) ->
      # ...
