Page Caching in Sinatra

[Jonas Nicklas]

Hey there,

I've been using Sinatra a bit, and all I can say is, it rocks! So I've been hacking around a bit, and implemented a simple-as-dirt solution for page caching. You could then put Sinatra behin an Apache proxy and serve the static files via Apache, and serve the rest via Sinatra. Good stuff.

Here goes:

===================

require 'fileutils'

module Caching

  

  def cache(text)

   # requests to / should be cached as index.html 

   uri = request.env["REQUEST_URI"] == "/" ? 'index' : request.env["REQUEST_URI"]

   

   # Don't cache pages with query strings. 

   unless uri =~ /\?/

      uri << '.html'

      # put all cached files in a subdirectory called 'cache'

      path = File.join(File.dirname(__FILE__), 'cache', uri)

      # Create the directory if it doesn't exist

      FileUtils.mkdir_p(File.dirname(path))

      # Write the text passed to the path

      File.open(path, 'w') { |f| f.write( text ) }    

    end

    return text

  end

end

Sinatra::EventContext.send :include, Caching

# you can then use it like this:

get '/' do

  cache erb( :index, :layout => 'app.erb' )
 
end

===============

Kinda brute force, but it's simple and does the trick.
