Advanced tools
css-combine is a module/command-line utility that combines CSS files by resolving their @import directives.
$ npm install [-g] css-combine
$ css-combine /path/to/file > /path/to/build
var combine = require('css-combine')
var raw = '/path/to/file'
/*
@import 'one.css';
@import url(two.css);
@import url('/path/to/three.css');
@import "../to/four.css";
@import url("five.css");
@import url(https://resolves-external-files.too);
body:before {
content: 'Just regular CSS'
}
*/
combine(raw).pipe(
fs.createWriteStream('/path/to/build')
)
If your @import directives use absolute file-system paths (like three.css in the above example), make sure you run css-combine from the root directory so that everything resolves correctly.
