Sinatra::LinkHeader ↑

Sinatra::LinkHeader adds a set of helper methods to generate link HTML tags and their corresponding Link HTTP headers.

Once you had set up the helpers in your application (see below), you will be able to call the following methods from inside your route handlers, filters and templates:

prefetch

Sets the Link HTTP headers and returns HTML tags to prefetch the given resources.

stylesheet

Sets the Link HTTP headers and returns HTML tags to use the given stylesheets.

link

Sets the Link HTTP headers and returns the corresponding HTML tags for the given resources.

link_headers

Returns the corresponding HTML tags for the current Link HTTP headers.

Classic Application ↑

In a classic application simply require the helpers, and start using them:

require "sinatra"
require "sinatra/link_header"

# The rest of your classic application code goes here...

Modular Application ↑

In a modular application you need to require the helpers, and then tell the application you will use them:

require "sinatra/base"
require "sinatra/link_header"

class MyApp < Sinatra::Base
  helpers Sinatra::LinkHeader

  # The rest of your modular application code goes here...
end
