Оказалось, из интересной заметки про микросервисы есть совсем небольшой alpine-rails

Сконфигурировать Rails для вывода production в STDOUT

Thu, 05 May 2016 08:24:49 +0100

For Rails 3.x, configure a logger in config/environments/test.rb:

config.logger = Logger.new(STDOUT)
config.logger.level = Logger::ERROR

This will interleave any errors that are logged during testing to STDOUT. You may wish to route the output to STDERR or use a different log level instead.

Sending these messages to both the console and a log file requires something more robust than Ruby’s built-in Logger class. The logging gem will do what you want. Add it to your Gemfile, then set up two appenders in config/environments/test.rb:

logger = Logging.logger['test']
logger.add_appenders(
    Logging.appenders.stdout,
    Logging.appenders.file('example.log')
)
logger.level = :info
config.logger = logger

Rails + SSE = попоболь

Прочитав простыню в http://www.sitepoint.com/mini-chat-rails-server-sent-events/
как подключается SSE в Rails.

ClojureScript + Datascript решает такую архитектурную проблему чуть более чем полностю.
