v2.1.0

⚠️ If you're somehow trying to migrate from RES 1.x to this version, please migrate to v2.0.0 first ⚠️

RubyEventStore

• Remove: Deprecated methods from previous release are gone [#946]

• Add: Record upcasting as a way to on-the-fly transform previous event versions into newer ones when reading [#836]

  Usage:

class Mapper < PipelineMapper
  def initialize(upcast_map: {})
    super(Pipeline.new(
      Transformation::Upcast.new(upcast_map),
    ))
  end
end

RubyEventStore::Client.new(
  mapper: Mapper.new(upcast_map: {
    'OldEventType' => lambda { |record|
      Record.new(
        event_type: 'NewEventType',
        data:        ...,
        metadata:    record.metadata,
        timestamp:   record.timestamp,
        valid_at:    record.valid_at,
        event_id:    record.event_id
      )
    }
  }),
  repository: ...
) 

• Add: Introduce explicit event type resolver [#837]

  Previously we'd always expect that a string with event type or anything responding to to_s can be passed to APIs expecting event type — of_type, subscribe etc. That stays as a default for backward compatibility but can be customized so that:

class SomeEvent < MyEvent
  self.event_type = "some.event"
end
      
client = RubyEventStore::Client.new(
  repository: InMemoryRepository.new,
  subscriptions: Subscriptions.new(event_type_resolver: ->(klass) { klass.event_type })
)
client.subscribe(lambda { |event| ... }, to: [SomeEvent]) 

# Previously this needed to be: [SomeEvent.event_type]
