broccoli-csssplit

Split Your CSS With Broccoli

Pass your tree to broccoli-csssplit and it will split any file (eg. foo.css) with more than 4095 selectors into separate files.

Be sure to select CSS files only in your input tree. broccoli-caching-writer will ensure that it can skip CSS Spliting if the files have not changed.

var pickFiles = require('broccoli-static-compiler');
 
var styles = pickFiles(tree, {
  srcDir: '/css',
  files: ['app.css'],
  destDir: '/css'
});
 
module.exports = csss(styles);
