Require a module that is incompatible with your Drupal Core version

lenient.sh

# Get lenient.
composer require mglaman/composer-drupal-lenient

# Add the module to the allow list. Use escapes for the quote signs. \" ... \"
composer config --merge --json extra.drupal-lenient.allowed-list '[\"drupal/module_with_incompatible_core_version\"]'

# You can check if the merge worked, either just take a look
# into the composer.json or use this command.
composer config --merge --json extra.drupal-lenient.allowed-list

lenient_allowed_list.json

"drupal-lenient": {
  "allowed-list": [
    "drupal/module_with_incompatible_core_version"
  ]
}

Issue:

Managing dependencies in a Drupal project where certain modules may not be compatible with the Core version you are using.

Prerequisites:

Your project needs to be Composer managed.

Solution:

The code uses the mglaman/composer-drupal-lenient package to allow specific Drupal modules that are incompatible with the core version to be installed without causing version conflicts.

Learn more in the Lenient install tutorial.

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.

  // UMD build and no *.min.css; Drupal aggregates them either way.
