A gem that provides a rack middleware to interact with Superfeedr[http://superfeedr.com/]‘s PubSubHubbub API. It let you subscribe, unsubscribe and receive incoming feed notifications. This should work with any Rack-compatible framework, as well as fully managed platforms like Heroku.

Warning : version 0.3 (July 2014) introduces a lot of breaking changes compared to previous versions. Upgrade carefully!


gem install rack-superfeedr


You first need a subscriber account with Superfeedr.

Warning : your web application needs to be accessible for Superfeedr to send notifications. If you want to test it locally, we suggest you use it with a tool like Passsageway which will make your local port accessible from the outside world.


See the example… and check the docs for more details.


Tested with Rails 3.2, but should work with any Rails version that supports Rack.

Install the gem (using bundle), and then in config/application.rb, inside the class Application < Rails::Application block, just add the following line.

config.middleware.use Rack::Superfeedr do |superfeedr|
