Loomio::Event

Loomio::Event is a simple way to perform pub-sub style events from within your rails app.

Installation

Add this line to your application's Gemfile:

gem 'loomio_event'

And then execute:

$ bundle

Or install it yourself as:

$ gem install event_bus

Usage

Loomio Event caters to a Publish / Subscribe style for rails events. To listen to an event, create an initializer with the following:

Loomio::Event.configure do |config|
  config.listen('my_event_name') { |param| puts param }
end

NB: listen can take multiple event names for the same block, which can take an arbitrary number of params:

config.listen('my_event_name', 'my_other_event_name') { |param1, param2| puts "#{param1}, #{param2}" }

Then, to trigger the event in your application, call broadcast, and pass it your parameters, like so:

Loomio::Event.broadcast('my_event_name', 'Hello, world!')
