I don't want listen both queue, i think i have describe you briefly what i
want to achieve.

1) Amqp.js : This is the server in nodejs. when user connect to server.
server will generate the queue, and tell client to listen to that queue in
passive mode. in short client don't have access for create queue. if i will
listen from both side then queue will not destroy automatically becuase my
server (amqp.js) file's queue consuming it. so i want that when client
(queue.js) killed or close. at that time server will notify that queue is
destroyed, and i will get all data like routing key when it destroy.

Whereas *amq.rabbitmq.event *is the exchange, that will monitor all the the
*connection.queue("eventListener", { exclusive: true } ,  function(q){*
 * q.bind("amq.rabbitmq.event","");*

* //i want to listen all events here when queue destroy when client app
* q.subscribe(function (message, headers, deliveryInfo, messageObject) {*
* console.log(JSON.stringify(headers));*
*  })*
* });*

Above code will generate queue that will listen all the event like exchange
create, exchange delete, binding, queue created, queue delete, etc..
I read in the documentation of the amqp-event plugin that it will deliver
all the event which are happing to all exchanges on the rabbitmq server.

2) queue.js : it is the simple client that have only read access to queue
in passive mode only. if any event goes to this client like queue delete
then it's not helpful to me.
My main purpose is to listen event and get message when queue.js will be
killed or application killed in android.

Hope you understand. if you made any correction in my file then please send
it to me with correction.
