.on( 'error', (err) -> console.error "RabbitMQ error", err )
.on( 'ready', () -> console.log "Connected to RabbitMQ" )

.queue( 'testQueue', (queue) -> console.log "Connected to Queue", queue.name )
  .bind( 'stream', '#' )
  .bind( 'stream2', 'routing.key' )
  .subscribe( (message, header, deliveryInfo) -> )

.queue( 'queue2' )
  .bind( 'search', '#.ok' )

.queue( 'queue3', passive:true )

.connect( (err, amqp) ->

  if err
    throw err
