RailsFeatureFlip

This gem provides a generator to create feature flip config classes that can be used to define what features can be used in what stage and/or how they should behave in what stage.

bin/rails generate rails_feature_flag:feature Thing enabled:boolean foo bar

This will create:
    config/features/thing_feature.rb

Then in application.rb:
    config.x.features.help_center = Features::Thing.new(enabled: false, foo: 'bar', bar: 'baz')
With that you can use:
    App.features.thing.enabled?
    # => false
    App.features.thing.foo
    # => bar

The main benefit over the default config.x namespace is the readability in code whereas

if App.features.thing.enabled?
  # do something with feature "thing"
end

is more readable than

if Rails.env.development?
  # do something with feature "thing" in development stage
elsif Rails.env.test?
  # do something with feature "thing" in test stage
else
  # do something with feature "thing" in production stage
end

Install the gem and add to the application's Gemfile by executing:

$ bundle add rails-feature-flip

After that setup the gem to work in your app by executing:

$ bin/rails generate rails_feature_flip:install

To get usage instructions run:

$ bin/rails generate rails_feature_flip:feature -h

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
