Dispatch rider is a pub/sub kind of library that allows you to publish a message to a notification system (like Amazon SNS) and then you can subscribe to the channels that you subscribed to and start handling the messages.
Add this line to your application's Gemfile:
gem 'dispatch-rider'
And then execute:
$ bundle
Or install it yourself as:
$ gem install dispatch-rider
All configuration can be loaded from a hash instead of being done like the examples below. (currently only implemented for the publisher)
eg:
publisher = DispatchRider::Publisher.new
publisher.configure({
notification_services: {
file_system: {}
},
destinations: {
file_foo: {
service: :file_system,
channel: :foo,
options: {
path: "test/channel",
}
}
}
})You can load this configuration hash from a YAML file or something, whatever works well for your environment.
# For the publishing side
publisher = DispatchRider::Publisher.new
publisher.register_notification_service(:aws_sns)
publisher.register_destination(:sns_foo, :aws_sns, :foo, :account => 777, :region => 'us-east-1', :topic => 'aliens')
publisher.publish(:destinations => :sns_foo, :message => {:subject => "bar_handler", :body => {"bar" => "hola"}})
# For the subscribing side
module BarHandler
class << self
def process(options)
throw :process_was_called
end
end
end
subscriber = DispatchRider::Subscriber.new
subscriber.register_queue(:aws_sqs)
subscriber.register_handler(:bar_handler)
subscriber.setup_demultiplexer(:aws_sqs)
subscriber.process publisher.register_notification_service(:file_system)
publisher.register_destination(:file_foo, :file_system, :foo, :path => "some/folder")
publisher.publish(:destinations => :file_foo, :message =>
{:subject => "bar_handler", :body => {"bar" => "hola"}}) publisher.publish(:destinations => [:sns_foo, :file_foo], :message =>
{:subject => "bar_handler", :body => {"bar" => "hola"}})- Fork it
