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

As mentioned this behavior is not in node.js core. But you can use hij1nx's EventEmitter2:

https://github.com/hij1nx/EventEmitter2

It won't break any existing code using EventEmitter, but adds support for namespaces and wildcards. For example:

server.on('foo.*', function(value1, value2) {
  console.log(this.event, value1, value2);
});
