Raes

Raes is Rails Async Event Store. Executes a class method call asynchronously. Others use Rails' Active Job and Active Storage services to store files.

• Raes (※)

Usage

Dispatch a class name that has a call method.

Simple Echo

Same echo call method.

class SimpleEcho
  include Raes::UseCaller

  def initialize(params)
    @params = params
  end

  def call
    @params
  end
end

When executed, { message:'Hi' } is saved in state.

Raes.dispatch(SimpleEcho, { message: 'Hi' })
Raes.search(SimpleEcho).last.state # "{\"message\":\"Hi\"}"

File Maker

Rewrite old file newly.

class FileMaker
  include Raes::UseCaller
  include Raes::UseStorage

  def initialize(params)
    @raes_storage_id = params[:raes_storage_id]
  end

  def call
    old_file = raes_storage_content
    new_file = old_file + 'bar'

    raes_storage_attach({ io: StringIO.new(new_file), filename: 'new_file.txt', content_type: 'text/plain' })
  end
end

Content will be changed to the new file.

Raes.dispatch(FileMaker, raes_storage: { io: StringIO.new('foo'), filename: 'old_file.txt', content_type: 'text/plain' })
Raes.search(FileMaker).last.storages.first.content.download # foobar
