Awesome
Welcome to Sqwish
A Node based CSS Compressor. It works like this.
require('sqwish').minify('body { color: #ff33cc; }');
// => "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:
selectors[,more selectors] {
property: value;
another-property: another value;
}
Strict Optimizations
Aside from regular minification, in <code>--strict</code> mode Sqwish will combine duplicate selectors and merge duplicate properties.
/* before */
div {
color: orange;
background: red;
}
div {
color: #ff33cc;
margin: 1px 0px 1px 0px;
}
/* after */
div{color:#f3c;background:red;margin:1px 0}
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 <code>sink-test</code> submodule
$ npm install --dev
Tests can be added in <code>tests/tests.js</code>, and then run as such:
$ npm test
