Prevent empty views blocks from getting rendered even if they are empty.

Issue: https://www.drupal.org/project/drupal/issues/953034

my_module.module
<?php

use Drupal\views\Plugin\Block\ViewsBlock;

/**
 * Implements hook_block_alter().
 */
function hook_block_alter(array &$definitions) {
  foreach ($definitions as $block_id => &$block_definition) {
    if ($block_definition['class'] === ViewsBlock::class) {
      $block_definition['class'] = 'Drupal\my_module\Plugin\Block\ViewsBlock';
    }
  }
}

ViewsBlock.php
<?php

namespace Drupal\my_module\Plugin\Block;

use Drupal\views\Plugin\Block\ViewsBlock as ViewsBlockCore;

/**
 * Replaces the generic Views block.
 */
class ViewsBlock extends ViewsBlockCore {

  /**
   * {@inheritdoc}
   */
  public function build() {
    if (empty($this->view->result) && empty($this->view->empty)) {
      // Without caching.
      // return ['#cache' => ['max-age' => 0]];
      // With hard caching.
      return [];
    }

    return parent::build();
  }

}

Issue:

Sometimes blocks are rendered even when they are empty and even if the setting in views is activated that they should not be rendered when empty. This might be the case in combination i.e. with lazy loading. If an empty block is rendered, this may have impact on  the layout because the empty block might still have margins or paddings

Solution:

This snippet replaces the generic Views block and checks "manually" whether or not the block is empty.

Replace Tagify CDN-loaded contrib library with a local npm asset in Drupal

install_libraries_locally.sh
composer require npm-asset/yaireo--tagify:4.35.4
my_module.module
/**
 * Implements hook_library_info_alter().
 *
 * The tagify module loads Tagify from cdnjs.cloudflare.com. Serve it from
 * npm-asset/yaireo--tagify in /libraries instead, so no request reaches a
 * third party and the widget keeps working behind restrictive firewalls.
 */
function my_module_library_info_alter(array &$libraries, string $extension): void {
  if ($extension !== 'tagify') {
    return;
  }

  // Assigning replaces the CDN entries. The npm package ships an unminified
  // UMD build and no *.min.css; Drupal aggregates them either way.
  $libraries['tagify']['js'] = [
    '/libraries/yaireo--tagify/dist/tagify.js' => ['minified' => FALSE],
  ];
  $libraries['tagify']['css']['component'] = [
    '/libraries/yaireo--tagify/dist/tagify.css' => ['minified' => FALSE],
  ];
  $libraries['tagify_polyfils']['js'] = [
    '/libraries/yaireo--tagify/dist/tagify.polyfills.min.js' => ['minified' => TRUE],

Filter user entity reference field options to active users only

Option 1 (recommended): custom entity reference selection handler. Further options down below.

ActiveUserSelection.php
<?php

namespace Drupal\my_module\Plugin\EntityReferenceSelection;

use Drupal\Core\Entity\Plugin\EntityReferenceSelection\UserSelction;
use Drupal\Core\StringTranslation\TranslatableMarkup;

#[EntityReferenceSelection(
  id: "default:active_user",
  label: new TranslatableMarkup("User selection (only active users)"),
  entity_types: ["user"],
  group: "default",
  weight: 1
)]
class ActiveUserSelection extends UserSelection {

  /**
   * {@inheritdoc}
   */
  protected function buildEntityQuery($match = NULL, $match_operator = 'CONTAINS') {
    $query = parent::buildEntityQuery($match, $match_operator);
    $query->condition('status', 1);

    return $query;
  }

}

After implementing that plugin, you need to activate it on the entity form display for the field you want it.
