Rack::Relations

Dynamically add rel="nofollow noopener noreferrer" to links on your page, so you don't have to remember to do it yourself. This is useful if you include links in your app to user-submitted URLs, to which you don't want to confer SEO benefits nor expose your users to potential phishing via window.opener.

Installation

Add this line to your application's Gemfile:

gem 'rack-relations'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rack-relations

Usage

Add to your Rack app like so:

# Rack
use Rack::Relations::Middleware

# Rails, config/application.rb
config.middleware.use Rack::Relations::Middleware

Optionally pass it domains to safelist and not apply this attribute, as an array of strings (for exact domain matches) or regular expressions (for more fine-grained specificity):

config.middleware.use Rack::Relations::Middleware,
  safelist_domains: ["example.com", /\.org\Z/]

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. 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 tags, and push the .gem file to rubygems.org.
