Static Sites with Ruby on Heroku/Cedar

Sometimes you just have a static website with one or two pages. Here is a simple way to host your static site and cache it on Heroku using a Rack app.

Your folder should be organized like this:

- MySite
  |- Gemfile
  |- public
    |- index.html
    |- images
    |- js
    |- css

In Gemfile file add the following:

source :rubygems

gem 'rack'

You should use bundler to generate the Gemfile.lock file:

    rack (1.4.1)



In file add the following:

use Rack::Static,
  :urls => ["/images", "/js", "css"],
  :root => "public"

run lambda { |env|
      'Content-Type'  => 'text/html',
      'Cache-Control' => 'public, max-age=86400'
    },'public/index.html', File::RDONLY)

This assumes that your template uses relative references to the images and stylesheets. Go ahead and deploy the app. If you are not sure how to deploy to Heroku check out the quickstart guide.

And there you go, a static site being served on Heroku completely cached and easily served using a single dyno.
