Drippings

Drippings is a gem used to quickly create drip campaigns within rails apps without boilerplate de-duping logic

Usage

To define a drip, create a subclass of Drippings::ProcessJob which implements process. For example:

class LeadFollowupJob < Drippings::ProcessJob
  
  # @param lead [Lead] the lead to email
  def process(lead)
    MessageSenderService.send(body: 'Hello, buy my product!', lead: lead)
  end
end

ProcessJob subclasses can also accept any ad hoc arguments you may need:

class LeadFollowupJob < Drippings::ProcessJob
  
  # @param lead [Lead] the lead to email
  def process(lead, phone:, transactional:)
    MessageSenderService.send(
      body: 'Hello, buy my product!',
      lead: lead,
      phone: phone,
      transactional: transactional
    )
  end
end

To define the schedule on which you want your drips to process, register a drip by defining a drip name, process job subclass, scope, and any additional arguments you want to pass via options:

# config/initializers/drippings.rb
Drippings.configure do |config|
  config.register(
    "Lead::Followup",
    LeadFollowupJob,
    -> { Lead.active },
    options: {
      phone: '555-555-5555',
      transactional: true,
    }
  )
end

You can also define a time to send your messages by defining a wait_until (formatted as a hash of time units) and a time_zone, which can either be a proc do determine a timezone per resource, or a string to define a timezone for all resources:

Drippings.configure do |config|
  config.register(
    "Lead::Followup",
    LeadFollowupJob,
    -> { Lead.active },
    wait_until: { hour: 16 }, # 4PM
    time_zone: ->(lead) { lead.time_zone },
    options: {
      phone: '555-555-5555',
      transactional: true,
    }
  )
end

Finally, add the Drippings::Kickoff job to your recurring job scheduler, such as sidekiq-scheduler

# sidekiq.yml
drippings_kickoff_job:
    cron: '*/15 * * * * UTC'
    class: Drippings::KickoffJob
    enabled: false
