Enable GZIP support on Heroku

So, I was working in a project with about 2MB of assets being loaded everytime without a good cache and this, my good friend, isn't cool. I was almost writing a Rack Middleware to handle this, when I found the heroku-deflater gem.

So, it's simple. Add this to your gemfile:

group :production do
   gem 'heroku-deflater'
end 

This will gzip every asset (except images) and (really) improve your application assets' load time.

Before:

After:

Hope you liked it!
