How to enable uglifier for js compression and compress css in development?

Question

Ruby on Rails

Gemfile:
gem 'uglifier'
development.rb:

config.assets.prefix = "/dev-assets"
  config.assets.debug = false
  config.assets.raise_runtime_errors = true
  config.assets.digest = true
  config.assets.js_compressor = :uglifier
  config.assets.compress = true

I end up with a large application.js and application.css glued together that assemble correctly but don't shrink at all. I would like to test in development before production. First time doing this. Is it possible to shrink in development?

Answer 1

Why not just do:

RAILS_ENV=production rake assets:precompile
RAILS_ENV=production rails s
