Performance improvements with Drupal 8 Libraries

by Rikki Bochow /

For a long time I’ve been compiling my Sass into a single CSS file - styles.css, but recently, with our component based design/frontend process and Drupal 8’s lovely Library system I’ve been wondering if the single file was still a good idea.
