I want to include a CSS and a JavaScript file, without linking them to a theme in particular.
Sometimes, I create small sites without modifying the theme at all, but I still need some minor CSS/JavaScript changes that don't justify creating a sub-theme. I wouldn't mind creating two "quick" and "global" files directly on the Drupal directory just for that.
Can this be done?
Add a module, give it a libraries file (MODULE.libraries.yml):
global:
js:
/js.js: {}
css:
theme:
/css.css: {}
In the .module file, implement hook_page_attachments:
function MODULE_page_attachments(array &$attachments) {
$attachments['#attached']['library'][] = 'MODULE/global';
}
When you enable the module (or clear cache if it's an existing module), the CSS and JS will be included on every page.
