Bunny is a synchronous RabbitMQ client that focuses on ease of use. With the next 0.9 release (currently in master), it is feature complete, supports all RabbitMQ 3.0 features and is free of many limitations of earlier versions.

Bunny 0.9 and more recent versions support Ruby 1.9.3, 1.9.2, JRuby 1.7, Rubinius 2.0 and 1.8.7.

Bunny 0.8.x and later versions only support RabbitMQ 2.x and 3.x. Bunny 0.7.x and earlier versions support RabbitMQ 1.x and 2.x.

Bunny is a very old library with a lot of missing functionality. It also implements an older version of the spec and may or may not work with future RabbitMQ versions. As such, Bunny needed serious internal changes. We (the maintainers) make our best to keep the new version as backwards compatible as possible but within reason.

See this announcement to learn more.

To install Bunny 0.9.x with RubyGems:

gem install bunny --pre

To use Bunny 0.9.x in a project managed with Bundler:

gem "bunny", ">= 0.9.0.pre6" # optionally: , :git => "git://github.com/ruby-amqp/bunny.git", :branch => "master"

Below is a small snippet that demonstrates how to publish and synchronously consume ("pull API") messages with Bunny 0.9.

For a 15 minute tutorial using more practical examples, see Getting Started with RabbitMQ and Ruby using Bunny.

require "bunny"

# Start a communication session with RabbitMQ
conn = Bunny.new
conn.start

# open a channel
ch = conn.create_channel

# declare a queue
q  = ch.queue("test1")

# declare default direct exchange which is bound to all queues
e  = ch.default_exchange

# publish a message to the exchange which then gets routed to the queue
e.publish("Hello, everybody!", :routing_key => 'test1')

# fetch a message from the queue
delivery_info, metadata, payload = q.pop

puts "This is the message: #{payload}"

# close the connection
conn.stop

Bunny API Reference.

Bunny a mailing list. We encourage you to also join the rabbitmq-discuss mailing list. Feel free to ask any questions that you may have.

For more immediate help, please join #rabbitmq on irc.freenode.net.

To subscribe for announcements of releases, important changes and so on, please follow @rubyamqp on Twitter.

If you find a bug, poor default, missing feature or find any part of the API inconvenient, please file an issue on GitHub. When filing an issue, please specify which Bunny and RabbitMQ versions you are using, provide recent RabbitMQ log file contents if possible, and try to explain what behavior you expected and why. Bonus points for contributing failing test cases.

Other widely used Ruby RabbitMQ clients are Hot Bunnies (JRuby-only) and amqp gem. Both are mature libraries and require RabbitMQ 2.x or 3.x.

First, clone the repository and run

bundle install --binstubs

then set up RabbitMQ vhosts with

./bin/ci/before_build.sh

(if needed, set RABBITMQCTL env variable to point to rabbitmqctl you want to use)

and then run tests with

./bin/rspec -cfs spec

After that create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on GitHub.
