## Usage

Open a connection to EventStore:

return 404 unless stream.exists?
stream_version = -1
stream.replay_forward do |event|
  if event.type == 'UserAccountClosed'
    return [410, JSON.pretty_generate({
      errors: 'User account already closed'
    })]
  end
  stream_version = event.number
end
return [400, JSON.pretty_generate({
  errors: "Stream #{stream} unexpectedly empty"
})] if stream_version < 0
event = EsHttpClient.create_event('UserAccountClosed', { userId:  user_id })
stream.append(event, stream_version) ? 200 : 409
