duplex-emitter

Turns a duplex stream into an event emitter.

For instance, when you connect a TCP server and a TCP client using this, when the client emits, the event gets propagated to the server and vice-versa.

Create

var s = net.connect(...);

var duplexEmitter = require('duplex-emitter');
var emitter = duplexEmitter(s);

Emit

You can emit events. They will be serialized (to JSON) and piped to the stream.

emitter.emit('event1', arg1, arg2); // Send event to the other side

Receive

You can listen for events from the peer:

// Got event from the peer
emitter.on('event2', function(arg1, arg2), {
  //...
})
