Dor::Event::Client

Dor::Event::Client is a Ruby gem that acts as a client for the event services provided by dor-services-app.

Currently, the client only supports the asynchronous creation of events (via RabbitMQ). In the future, other operations (including synchronous operations via HTTP) may be supported. At present, additional event operations are supported by dor-services-client.

Add this line to your application's Gemfile:

gem 'dor-event-client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dor-event-client

To configure and use the client, here's an example for a Rails app:

In config/initializers/dor_event_client.rb:

Dor::Event::Client.configure(hostname: Settings.rabbitmq.hostname,
  vhost: Settings.rabbitmq.vhost,
  username: Settings.rabbitmq.username,
  password: Settings.rabbitmq.password)

# Create and list events for an object
Dor::Event::Client.create(druid:, type:, data:)

# For example:
Dor::Event::Client.create(
  druid: 'druid:bb408qn5061', 
  type: 'druid_version_replicated', 
  data {
      host: 'preservation-catalog-qa-02.stanford.edu',
      version: 19,
      invoked_by: 'preservation-catalog',
      parts_info: [
        {
          md5: '1a528419dea59d86cfd0c456e9f10024',
          size: 123630,
          s3_key: 'bb/408/qn/5061/bb408qn5061.v0019.zip'
        }
      ],
      endpoint_name: 'aws_s3_east_1'
    }:
  )

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
