Module: DerivativeRodeo::Services::UrlService

Defined in:
lib/derivative_rodeo/services/url_service.rb

Overview

Note:

It is a good design idea to wrap a library (in this case HTTParty). The goal is to expose the smallest interface and make it something that would be easy to swap out.

A utility class for handling general URLs. Provided as a means of easing the implementation logic of those that use this class.
