FeatureFlagger

Partially release your features.

Installation

Add this line to your application's Gemfile:

gem 'feature_flagger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install feature_flagger

Configuration

By default, feature_flagger uses the REDIS_URL env var to setup it's storage. You can configure this by using configure like such:

1. In a initializer file (e.g. config/initializers/feature_flagger.rb): ```ruby require 'redis-namespace' require 'feature_flagger'

FeatureFlagger.configure do |config| namespaced = ::Redis::Namespace.new("feature_flagger", redis: $redis) config.storage = FeatureFlagger::Storage::Redis.new(namespaced) end

2. Create a `rollout.yml` in _config_ path and declare a rollout:
```yml
account: # model name
  email_marketing: # namespace (optional)
    new_email_flow: # feature key
      description:
        @dispatch team uses this rollout to introduce a new email flow for certains users. Read more at [link]

1. Adds rollout funcionality to your model: ruby class Account < ActiveRecord::Base include FeatureFlagger::Model # .... end

Usage

account = Account.first

# Release feature for account
account.release(:email_marketing, :new_email_flow)
#=> true

# Check feature for a given account
account.rollout?(:email_marketing, :new_email_flow)
#=> true

# Remove feature for given account
account.unrelease(:email_marketing, :new_email_flow)
#=> true

# If you try to check an inexistent rollout key it will raise an error.
account.rollout?(:email_marketing, :new_email_flow)
FeatureFlagger::KeyNotFoundError: ["account", "email_marketing", "new_email_flo"]
