I am studying sydekiq documentation for my Ruby on Rails application.
Railscasts episode 366 on Sidekiq (min 7:00) says that in order to use the web interface it is necessary to add the following gems to the Gemfile:
gem 'sinatra', require: false
gem 'slim'
Since the monitoring wiki section of the official mperham repository does not even mention these gems, I am wondering whether these gems are not more required for Sidekiq (the above Railscasts episode dates back to 2012) or they are still required.
