Question

Is it possible to unload modules in nodejs?
In other words: clear event listeners, timeouts, and intervals.

These modules are “sub-files” of my project, and i could overwrite the .on(), and .once(), but what about timeouts and intervals?

Answer 1

No, not that I’m aware of.

You can remove all event listeners on an emitter by calling myEmitter.removeAllListeners(). As for clearing the timeouts and intervals, call clearTimeout(timeoutName) and clearInterval(intervalName) respectively.

Example:

var x = 0;
var myInterval = setInterval(function(){
  console.log('hello');
  if (x > 5) clearInterval(myInterval);
  x += 1;
},1000);

Hopefully this helps.
