A wrapper around https://github.com/squaremo/amqp.node to make consuming and publishing dead easy.
A simple wrapper to https://github.com/squaremo/amqp.node.
Allows you to have any number of publish queues, one consume queue and to perform consume and publish operations.
deadLetterExchangeoption which will cause the queue to be declared with that dead letter exchange.
deadLetterRoutingKeyare special options, in that as well as being passed through to
ch.assertQueue()to ensure the dead lettering behaviour occurs, a queue will be declared of the same name with the
-dead-lettersuffix, with a binding declared on the dead letter exchange for the dead letter routing key. This means that when a message is dead lettered on that queue it will have somewhere to go without you having to set up a dead lettering queue manually.

Start a rabbit server, preferably a 'throw away' one with fresh state. You can do this like so if you have docker:
docker run --rm -p 5672:5672 dockerfile/rabbitmq
tests/config.js currently assumes you are using
boot2docker (on a
Mac) so you may need to hack that stuff (or it may just work as it should just
use localhost if it's not there... unproven though.)
