What is clean-css?

Clean-css is a node.js library for minifying CSS files. It does the same job as YUI Compressor's CSS minifier but much faster thanks to speed of node.js V8 engine.

Usage

How to install clean-css?

npm install clean-css

How to use clean-css?

You can minify one file public.css into public-min.css via:

cleancss -o public-min.css public.css

To minify the same public.css into standard output skip the -o parameter:

cleancss public.css

Or more likely you would like to do something like this:

cat one.css two.css three.css | cleancss -o merged-and-minified.css

Or even gzip it at once:

cat one.css two.css three.css | cleancss | gzip -9 -c > merged-minified-and-gzipped.css.gz

How to use clean-css programatically

var cleanCSS = require('clean-css');

var source = "a{font-weight:bold;}";
var minimized = cleanCSS.process(source);

How to run clean-css tests?

You need vows testing framework (npm install vows) then simply run:

make test
