Observable Base Class
The Observable
base class makes and subclass trigger events and accept event listeners. It is similar to an EventEmitter.
Example:
class Test extends Observable {
doSomething() {
// work
this.trigger('work-done', {some: params})
}
}
let test = new Test();
test.on('work-done', (params) => yay());
With Sockets:
You can also bind sockets (SocketIO) to an Observable
and all events will also be emitted or received via the socket. See the API below for binding sockets.
Methods:

: Listen to an event.trigger(event)
: trigger an event.once(event, listener)
: trigger an event once.bindSocketServer(socket)
: Emit triggers on this socket.bindSocketClient(socket)
: Listen for events on this socket.
