Best way to handle timeouts on acknowledgements

[jjoschyy]

Dear LearnBoost

Using the acknowledgements "feature" from socket.io works fine. Just in case the server does not respond (e.g. due to connection loss or high server load), the acknowledgement callback will never be fired. Therefore, I tried to implement timeouts for acknowledgements.

The following example is working, but it can happen that both, timeoutErrorFn and acknCallbackFn, will be executed. Is there an better, more common way to solve this problem? Do you think about adding timeouts to the "emit" as basic feature?

Thank you very much for any idea!

var timeoutId = setTimeout(timeoutErrorFn, 500);

var acknCallbackFn = function(err, userData){
  clearTimeout(timeoutId)
  //manage UserData
}

socket.emit('getUserData', acknCallbackFn);
