Overview

Simple interface for running background jobs as commands. Meant to be inherited like this: class SidekiqService < Utilisable::BackgroundService

def initialize(options)
  super(options, ServiceObjectWorker)
end

end

Needs a worker to work, that should look like this: class ServiceObjectWorker

include Sidekiq::Worker
sidekiq_options queue: :default, retry: true

def perform(klass, *args)
  klass.constantize.call(args)
end

end

Now you can create a command like this: class SimpleService < SidekiqService

attr_reader :foo

def initialize(foo, options = {})
  super(options)
  @foo = foo
end

private

def perform
  puts foo
end

end

And invoke it like this: SimpleService.call(foo, background: true, perform_in: 15.minutes)
