Performance Optimisation

Performance improvements with Drupal 8 Libraries

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. Looking at the amount of unused CSS loading into any given page was a little bit painful.

Base themes without the bloat

Base themes in Drupal are incredibly useful but often add bloat to the finished sub-theme when care isn’t taken to remove unnecessary css files, or files that are 5% used and 95% overridden. When porting aGov to Drupal 8 we took the opportunity to improve how it’s theme inheritance is managed, making it easier to create trim, lightweight sub-themes.
