Rollout::UI

Minimalist UI for the rollout gem that you can just mount as a Rack app and it will just work.

Usage with Rails

Add it to your application's Gemfile:

gem 'rollout-ui'

Mount it

Rails.application.routes.draw do
  mount Rollout::UI::Web.new => '/admin/rollout'

  # ...
end

And to configure it with your Rollout instance, you can put your configuration in routes.rb or in a standalone initializer.

Rollout::UI.configure do
  instance { $rollout }
end

Authentication

If you are using Rails, you can put constraints on your mount.

So in case of usafe with Devise, your constraints might look like:

module Constraint::Admin
  def self.matches?(request)
    id = request.session["warden.user.user.key"].try(:[], 0).try(:[], 0)
    return false if id.blank?

    user = User.find_by(id: id)
    user&.admin?
  end
end

Rails.application.routes.draw do
  mount Rollout::UI::Web.new => '/admin/rollout', constraints: Constraints::Admin

  # ...
end

API Endpoints

The index and show routes can also respond with JSON data instead of HTML when the request's Accept header is application/json

The index route also accepts query parameters to filter by user or group: /admin/rollout?user=someone /admin/rollout?group=developers

Logging

To get the most out of rollout-ui, we recommend you to turn on logging on your rollout instance to see history of changes in the UI.

$rollout = Rollout.new(Redis.current, logging: { history_length: 100, global: true })

To also see who updated states of your rollouts, you can configure actor and actor_url. So if you are using Rails with Devise, your configuration might look like:

Rollout::UI.configure do
  instance { $rollout }
  actor { current_user&.username }
  actor_url { |actor| "/#{actor}" }
end

To run this project for development in isolation:

bundle install
bundle exec rerun rackup

Alternatively you can also configure which Redis with:

REDIS_HOST=localhost REDIS_PORT=6379 REDIS_DB=10 be rerun rackup
