Here's how you can do this:

1. Instantiate the Angular EventEmitter in the app.component
2. Pass it to the Skylink Wrapper constructor and keep it in a member attribute of the class.
3. Emit the event with the recording value:

Skylink.on('recordingState', function (state, recordingId, link, error)

{ this.emmiter.emit("myRecordingIdEvent", recordingId) }

       4. Implement the event listener (handler) in app.component.
