  # Use environment names or environment variables:
  # break unless Rails.env.production? 
  break unless ENV['ENABLE_COMPRESSION'] == '1'
  
  # Strip all comments from JavaScript files, even copyright notices.
  # By doing so, you are legally required to acknowledge
  # the use of the software somewhere in your Web site or app:

The code is explained in further details at my article linked above.

thanks!

Something better of this solution?

I think my app slow down with this... a little...

We need the ability to compress only specific pages with this middleware
