Flaggle Rock

View on RubyGems

Flaggle Rock is a simple feature flagging gem for use with Ruby on Rails applications.

It is designed for easily hiding features from end users to help enable a fast-moving CI workflow. It currently does not aim to support more advanced features such as A/B testing.

Installation

Add Flaggle Rock to your Gemfile:

gem "flaggle_rock"

And install

bundle install

Generate the migrations, and run them to add feature flags to your database:

bundle exec rails generate flaggle_rock:install
bundle exec rails db:migrate

Usage

All flags are off by default. There is no need to explicitly create a new flag—turning it on will do this.

To enable/disable a flag:

Rock.on(:flag_name)
Rock.off(:flag_name)

To check whether a flag is on:

Rock.on?(:flag_name)
Rock.off?(:flag_name)

To remove a flag which is no longer used:

Rock.delete(:flag_name)

To remove all disabled flags:

Rock.delete_all_disabled

Future

Goals with Flaggle Rock include the creation of a web UI for easily administering flags.

Compatibility

Flaggle Rock has been tested with Rails 7 and PostgreSQL 11, but should work with older versions of Rails and other database engines.
