I am looking for a Ruby-based tool that can help me minify CSS

Searching for a CSS minifier that is compatible with Rails apps (not gziper) and doesn't require YUI compressor installation via command line. I'm developing a content management software where CSS is inputted into a textarea, then I need to minify it, gzip it, and send it to Amazon without any preprocessing through the command line. Please suggest any suitable solutions?

Online minifier services are also appreciated.

Answer №1

Another option to consider is using SASS with the parameters

:syntax => :scss, :style => :compressed
.

Answer №2

After much searching, I have discovered a true treasure:

'emerald-yui-minimizer'

Here's all that needs to be done:

gem "yui-minimizer", "~> 1.2.4", :require => "yui/minimizer"
....
minimizer = YUI::CssMinimizer.new
minimizer.minimize 'h1 {font-size: 2rem}            \np {line-height: 1.5}'

=> "h1{font-size:2rem}\\np{line-height:1.5}" 

Answer №3

Have you considered using Juicer?

Answer №4

1. Begin by installing Ruby and launching the program. 2. Once Ruby is installed, use the command 'gem install saas' and hit enter to download the necessary gem. 3. To compile your Sass code into compressed CSS, type 'sass --scss --style compressed [source file] [destination file]'.

For example: sass --scss --style compressed sass/_theme.scss css/theme.css
