Welcome to Sqwish
A Node based CSS Compressor. It works like this.
;// => "body{color:#f3c}"
CLI
Install it.
$ npm install -g sqwish
Use it like this:
$ sqwish app.css # default output is <file>.min.css therefore app.css => app.min.css
$ # or...
$ sqwish css/styles.css -o prod/something-else.min.css
Notes
Sqwish does not attempt to fix invalid CSS, therefore, at minimum, your CSS should at least follow the basic rules:
Strict Optimizations
Aside from regular minification, in --strict
mode Sqwish will combine duplicate selectors and merge duplicate properties.
/* before *//* after */
This mode can be enabled as so:
sqwish.minify(css, true);
on the command line
$ sqwish styles.css --strict
Developers
Be sure you have the proper testing harness set up ahead of time by installing the sink-test
submodule
$ npm install --dev
Tests can be added in tests/tests.js
, and then run as such:
$ npm test
