Artsy::EventPublisher

Lightweight helper for publishing events to rabbitmq in a pattern consistent with Artsy's ecosystem.

Add following line to your Gemfile

gem "artsy-event_publisher"

Example initialization:

# config/initializers/artsy-event_publisher.rb
Artsy::EventPublisher.configure do |config|
  config.app_id = "my-app" # identifies RabbitMQ connection
  config.enabled = true # enable/disable publishing events
  config.rabbitmq_url = "amqp(s)://<user>:<pass>@<host>:<port>/<vhost>" # required
  config.logger = Rails.logger
end

Publishing a sample event:

Artsy::EventPublisher.publish(
  "auctions", # topic
  "bidder.pending_approval", # routing key
  verb: "pending_approval",
  subject: {id: bidder.id.to_s, root_type: "Bidder", display: bidder.name},
  object: {id: sale.id.to_s, root_type: "Sale", display: sale.name},
  properties: {url: "..."} # optional additional properties
)
