Listen to All Emitted Events in Node.js

Question

In Node.js is there any way to listen to all events emitted by an EventEmitter object?

e.g., can you do something like...

event_emitter.on(\         


        

Answer 1

I know this is a bit old, but what the hell, here is another solution you could take.

You can easily monkey-patch the emit function of the emitter you want to catch all events:

function patchEmitter(emitter, websocket) {
  var oldEmit = emitter.emit;

  emitter.emit = function() {
      var emitArgs = arguments;
      // serialize arguments in some way.
      ...
      // send them through the websocket received as a parameter
      ...
      oldEmit.apply(emitter, arguments);
  }
}

This is pretty simple code and should work on any emitter.
