Feature flipping is the act of enabling or disabling features or parts of your application, ideally without re-deploying or changing anything in your code base.

The goal of this gem is to make turning features on or off so easy that everyone does it. Whatever your data store, throughput, or experience, feature flipping should be easy and have minimal impact on your application.

Installation

Add this line to your application's Gemfile:

gem 'flipper'

And then execute:

$ bundle

Or install it yourself with:

$ gem install flipper

Examples

The goal of the API for flipper was to have everything revolve around features and what ways they can be enabled. Start with top level and dig into a feature, then dig in further and enable that feature for a given type of access, as opposed to thinking about how the feature will be accessed first (ie: stats.enable vs activate_group(:stats, ...)).

require 'flipper'

# pick an adapter
require 'flipper/adapters/memory'
adapter = Flipper::Adapters::Memory.new

# get a handy dsl instance
flipper = Flipper.new(adapter)

# grab a feature
search = flipper[:search]

# check if that feature is enabled
if search.enabled?
  puts 'Search away!'
else
  puts 'No search for you!'
end

puts 'Enabling Search...'
search.enable

Of course there are more examples for you to peruse. You could also check out the DSL and Feature classes for code/docs.
