Implementing timeouts for node.js callbacks

Question

This is a typical situation in node.js:

asyncFunction(arguments, callback);

When asynFunction completes, callback

Answer 1

You probably need to come out with a solution of your own. Like

function callBackWithATimeout (callback, timeout) {
  var run, timer;
  run = function () {
    if (timer) {
      clearTimeout(timer);
      timer = null;
      callback.apply(this, arguments);
    }
  };
  timer = setTimeout(run, timeout, "timeout");
  return run;
}

and then

asyncFunction(arguments, callBackWithATimeout(callback, 2000));
