Configify

Configify captures a simple pattern for setting up configuration properties, as well as enable loading configurations from environment variables.

Add this line to your application's Gemfile:

gem 'configify-rb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install configify-rb

The following shows how to Configify a service class:

  class TestService
    include Configify

    configuration do
      env_variable_prefix 'TEST'

      property :base_url, default: 'localhost:8080'
      property :init_count
    end

    def initialize config: config
      @base_url = config.base_url
      @init_count = config.init_count
    end
  end

With configified service class above, TestService.configuration can be used to access the configuration class for the TestService. For example:

  config = TestService.configuration.new
  config.init_count = 100

  servcie = TestService.new config: config

Configify also supports loading properties from environment variables:

  # Assume the following environment variables
  # TEST_INIT_COUNT = 100
  # TEST_BASE_URL = 127.0.0.1:1234

  config = TestService.configuration.new
  config.load_from_env

  servcie = TestService.new config: config

The preferred way to initialise a instance is to utilize the with_config:

  service = TestService.with_config do |config|
    config.load_from_env
    config.init_count = 100
  end
