Pull the RSS feed for any website you want without worrying about the RSS feed existence or engine. The gem takes a URL address, finds the RSS feed, detects the generator and returns standardized feed interface as a simple Ruby object.
gem install rssable
In the most cases, all RSS feeds have the main structure standardized but sometimes it is required to parse the feed differently. Currently, following custom drivers are supported: wordpress, blogger, medium.com and jekyll. However, any RSS feed should work very well out of the box. If you will find a feed with the different structure that the gem does not handle well, please submit a new issue.
All you have to do is to subscribe to a given URL (without specyfing the RSS feed URL):
channel = RSSable.subscribe("http://pdabrowski.com/blog")
channel.title # => "Ruby on Rails and Stuff by Paweł Dąbrowski"If the RSS feed is not available it will return nil:
RSSable.subscribe("https://github.com") # => nilAccess the channel data
You can access the main channel attributes:
channel = RSSable.subscribe("http://pdabrowski.com/blog")
feed.title # => "Ruby on Rails and Stuff by Paweł Dąbrowski"
feed.description # => "Web development with Ruby on Rails"
feed.link # => "http://pdabrowski.com/blog"Access the channel items
You can access the channel items by calling #items on the channel instance:
items = channel.items
items.size # => 10
last_article = items.first
last_article.title # => "3 things that slow down and make your RSpec tests worse"
last_article.link # => "http://pdabrowski.com/blog/ruby-on-rails/testing/3-things-that-slow-down-and-make-your-rspec-tests-worse/"
