Wisper::Sidekiq

Provides Wisper with asynchronous event publishing using Sidekiq.

gem 'wisper-sidekiq', '~> 1.0'

gem 'wisper-sidekiq', '~> 0.0'

publisher.subscribe(MyListener, async: true)

The listener must be a class (or module), not an object. This is because Sidekiq can not reconstruct the state of an object. However a class is easily reconstructed.

Additionally, you should also ensure that your methods used to handle events under MyListener are all declared as class methods:

class MyListener
  def self.event_name
  end
end

When publishing events the arguments must be simple as they need to be serialized. For example instead of sending an ActiveRecord model as an argument use its id instead.

See the Sidekiq best practices for more information.

In order to define custom sidekiq_options you can add sidekiq_options class method in your subscriber definition - those options will be passed to Sidekiq's set method just before scheduling the asynchronous worker.

In order be able to schedule jobs to be run in the future following Scheduled Jobs you can add sidekiq_schedule_options class method in your subscriber definition - those options will be passed to Sidekiq's perform_in method when the worker is called.

This feature is not as powerful as Sidekiq's API that allows you to set this on every job enqueue, in this case you're able to set this for the whole listener class like:

class MyListener
  #...

  def self.sidekiq_schedule_options
    { perform_in: 5 }
  end

  #...
end

Or you can set this per event (method called on the listener), like so:

class MyListener
  #...

  def self.sidekiq_schedule_options
    { event_name: { perform_in: 5 } }
  end

  def self.event_name
    #...
  end

  #...
end

In both cases the perform_at option is also available.

The same Ruby versions as Sidekiq are offically supported, but it should work with any 2.x syntax Ruby including JRuby and Rubinius.

See the build status for details.

scripts/sidekiq
bundle exec rspec

To run sidekiq use scripts/sidekiq. This wraps sidekiq in rerun which will restart sidekiq when specs/dummy_app changes.
