ReleaseFeature

ReleaseFeature is feature toggle.

Installation

Using bundler, please add following line to your Gemfile.

gem 'release_feature'

Using gem

gem install release_feature

If you want to use latest main branch, please add following line to Gemfile.

gem 'release_feature', git: 'https://github.com/junara/release_feature.git', branch: 'main'

And then execute:

$ bundle install

Usage

Prepare client by configuring repository and initialize client.

You can select 4 repository types. From yaml (YamlRepository), hash (HashRepository) or ActiveRecord ( ActiveRecordRepository).

Client can have maximum 2 repositories (called to base_repository and extra_repository). extra_repository is optional.

If extra_repository is set, base_repository is merged by extra_repository. extra_repository setting has priority

Using hash repository

config = { features: { hogehoge_function: { development: { open_at: Time.now, close_at: Time.now + 60 * 60 * 24 * 30 } } } }
hash_repo = ReleaseFeature::Repository::HashRepository.new(hash: config)
client = ReleaseFeature::Client.new(environment: :development, base_repository: hash_repo)
client.permitted?(:hogehoge_function) #=> true
client.permitted?(:hogehoge_function, time: Time.now + 60) #=> true
client.permitted?(:hogehoge_function, time: Time.now - 60 * 60 * 24) #=> false

Using yaml repository

Create yaml in 'release_feature_config.yml'. Write following.

timezone: +09:00
features:
  hoge_feature:
    development:
      open_at: 2000-01-01 00:00
      close_at: 2999-12-31 23:59
    staging:
      open_at: 2030-11-01 10:00
      close_at: 2999-12-31 23:59
    production:
      open_at: 2040-12-01 10:00
      close_at: 2999-12-31 23:59
  puyo_feature:
    development:
      open_at: 2000-01-01 00:00
      close_at: 2999-12-31 23:59
    production:
      open_at: 2022-12-01 10:00
      close_at: 2999-12-31 23:59

Set zone to timezone . zone is defined in https://docs.ruby-lang.org/en/3.1/Time.html

zone: a timezone, which may be: A string offset from UTC. A single letter offset from UTC, in the range 'A'..'Z', 'J' (the so-called military timezone) excluded. An integer number of seconds. A timezone object; see Timezone Argument for details.

path = 'release_feature_config.yml'
yaml_repo = ReleaseFeature::Repository::YamlRepository.new(path: path)
development_client = ReleaseFeature::Client.new(environment: :development, base_repository: yaml_repo)
development_client.permitted?(:hoge_feature) #=> true

staging_client = ReleaseFeature::Client.new(environment: :staging, base_repository: yaml_repo)
staging_client.permitted?(:hoge_feature) #=> false

Using ActiveRecord repository

Model have four attributes (name (:string), environment (:string), open_at (:datetime), close_at (:datetime)

You cac migrate model by command line.

rails g model ReleaseFeatureItem name:string environment:string open_at:datetime close_at:datetime

Above command create following migration file.

class CreateReleaseFeatureItems < ActiveRecord::Migration[7.0]
  def change
    create_table :release_feature_items do |t|
      t.string :name
      t.string :environment
      t.datetime :open_at
      t.datetime :close_at

      t.timestamps
    end
  end
end

And run migrate.

rails db:migrate

Using created ActiveRecord for base_repository like this.

model = ReleaseFeatureItem # migrated by active_record
ReleaseFeatureItem.create!(name: 'hoge_feature', environment: 'development', open_at: '2000-01-01 00:00 +09:00', close_at: '2002-01-01 00:00 +09:00')
ar_repo = ReleaseFeature::Repository::ActiveRecordRepository.new(model: model)
client = ReleaseFeature::Client.new(environment: :development, base_repository: ar_repo)
client.permitted?(:hoge_feature) #=> false

Using "extra_repository"

Document under Construction

extra_repository overrides base_repository.

ex)

base_repository is yaml repository. extra_repository is ActiveRecord repository.

path = 'release_feature_config.yml'
yaml_repo = ReleaseFeature::Repository::YamlRepository.new(path: path)

model = ReleaseFeatureItem # migrated by active_record

ReleaseFeatureItem.create!(name: 'hoge_feature', environment: 'development', open_at: '2000-01-01 00:00 +09:00', close_at: '2002-01-01 00:00 +09:00')
ar_repo = ReleaseFeature::Repository::ActiveRecordRepository.new(model: model)

client = ReleaseFeature::Client.new(environment: :development, base_repository: yaml_repo, extra_repository: ar_repo)

# activerecord_repository override yaml_repository hoge_feature.
client.permitted?(:hoge_feature) #=> false

release_feature_item = ReleaseFeatureItem.find_by(name: 'hoge_feature', environment: 'development')
release_feature_item.update(close_at: '2099-01-01 00:00 +09:00')

# Default caching time (10 min) later

client.permitted?(:hoge_feature) #=> true

Caching

In default, repository data is cached 10 min (600sec). Caching time is changed by refresh_interval_sec parameter.

Following exmple, refresh interval is 1 hour (60 * 60 = 3600 sec ).

config = { features: { hogehoge_function: { development: { open_at: Time.now, close_at: Time.now + 60 * 60 * 24 * 30 } } } }
hash_repo = ReleaseFeature::Repository::HashRepository.new(hash: config)
client = ReleaseFeature::Client.new(environment: :development, refresh_interval_sec: 60 * 60, base_repository: hash_repo)

client.permitted?(:hoge_feature) #=> true
# Repository data is cached and is not loaded for 1 hour (60 * 60 sec).

With Rails app

In Ruby on Rails app, Bt Yaml repository, you can use like this.

class YourAppFlag
  include Singleton

  def initialize(environment = nil, path:)
    environment ||= Rails.env
    yaml_repo = ReleaseFeature::Repository::YamlRepository.new(path: path)
    @client = ReleaseFeature::Client.new(environment: environment.to_sym, base_repository: yaml_repo)
  end

  def permitted?(feature)
    @client.permitted?(feature.to_sym)
  end

  def run_if_permitted
    return unless permitted?
    yield
  end
end

# Before use, please prepare 'release_feature_config.yml'. See above.
flag = YourAppFlag.instance.new(path: 'release_feature_config.yml')

# Using simple boolean flag.
if flag.permitted?(:hoge_feature)
  put 'run if permitted.'
end

# Using block
flag.run_if_permitted do
  put 'run if permitted.'
end

Development

After checking out the repo, run bin/setup to install dependencies.

Then, run rake spec to run the tests.

Then, run steep check to run rbs check.

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.
