Usage

const Broadcaster = use('Broadcaster')
Broadcaster
      .event('MyAwesomeEvent')
      .into('MyAwesomeChannel')
      .with({"My Awesome Message"}).broadcast()

Of course from the client side do not use .listen method on channel - because this will listen for App.Events.MyAwesomeEvent event and not for MyAwesomeEvent. Use .on instead.

Even if you want to use .listen method - modify the Broadcaster and append to the event name App.Events.. Should be something like this:

event(event){
    this.broadcastEvent = "App.Events." + event
    return this
  }

As you see in Broadcaster there is method called .to(request) and it takes the socket.id from the cookies. Its kinda private message but for guests of your site.

To use it - take a look at
https://github.com/mikield/laravel-echo-server/blob/master/src/echo-server.ts#L224
and
https://github.com/mikield/laravel-echo-server/blob/master/src/echo-server.ts#L179

You can use this package too https://github.com/mikield/laravel-echo-server but I dont garantie latest updates from the main project!

But you can use .toOther(request), it will set the sokectId that shall be ignored and it works with the main laravel-echo-server repo.
