Why is my theme library load on every page?












1














I'm beginning with D8, but I work a lot with D7 and Magento. I follow the developer documentation to add a library in my theme, and I don't understand why it's loading it on every page. I only want attach it to a brunch of page with a preprocess hook. Could you help me please?



In my theme.libraries.yml I add this at the end:



hover3d:
js:
js/hover3d.js: {}


In my theme.info.yml I add under libraries "theme/hover3d".



Here is specific information:




  • I deactivated JavaScript/CSS compression in the back office and in my settings.local.php file

  • My theme is a sub theme of bootstrap_barrio

  • My Drupal version is 8.6.3

  • There is no custom / contrib modules yet

  • I discover it by inspecting my page


js




  • I don't really understand how JavaScript parts are loaded, but I suppose it's with lazy builders which are called placeholder and in D8 for rendering JavaScript there are two (or more) which are js-placeholder and js-bottom-placeholder. I see in my HTML structure that in the js-placeholder is only loaded modernizer and in the js-bottom-placeholder all the others. I don't know if this is a correct JavaScript rendering procedure, so I keep it here if it can help you.

          That's why it's loaded on every page. libraries in the theme info file is:




          A list of libraries (which can contain both CSS and JavaScript assets) to add to all pages where the theme is active.




          To add it contextually, attach it to a relevant render array. For example:



          function MYTHEME_preprocess_node(&$variables) {
          // Library will only be loaded when a node is rendered on the page.
          $variables['#attached']['library'] = 'theme/hover3d';
          }
