How to remove a configuration object from the active configuration in Drupal 10

If you have a Drupal 10 custom module defining a field storage configuration object and you face issues while reinstalling the module after uninstalling it, you may need to manually remove the configuration object. To do so, you can use different methods like hooks, Drush commands, and Drupal console commands.

Method 1: Using hook_uninstall()

function my_module_uninstall() {
  \Drupal::configFactory()->getEditable('the_setting.you.want.to.delete')->delete();
}

Implement the hook_uninstall() function in your custom module, replacing 'the_setting.you.want.to.delete' with the configuration object you want to delete. This will remove the configuration when the module is uninstalled.

Method 2: Using Drush

drush config-delete <config_name>

Use the Drush command to delete a configuration object by replacing '' with the name of the configuration object you want to delete. After deleting the configuration, make sure to clear the cache using 'drush cr'.

Method 3: Using Drupal Console

Drupal::configFactory()->getEditable('the_setting.you.want.to.delete')->delete();

Use the Drupal Console to open an interactive session and run the above command, replacing 'the_setting.you.want.to.delete' with the configuration object you want to delete. This functionality will be added to the Drupal Console as well.

Method 4: Deleting Multiple Configuration Objects

If you want to delete multiple configuration objects at once, you can use the following approach:

function my_module_uninstall() {
  $config_names = [
    'the_first_setting.you.want.to.delete',
    'the_second_setting.you.want.to.delete',
    'the_third_setting.you.want.to.delete',
  ];

  foreach ($config_names as $config_name) {
    \Drupal::configFactory()->getEditable($config_name)->delete();
  }
}

Implement the hook_uninstall() function in your custom module and add the configuration object names to the '$config_names' array. This will delete all the specified configuration objects when the module is uninstalled.

Method 5: Using EntityTypeManager to Delete Configuration Entities

When working with configuration entities, it's better to use the entity storage system for deleting them. This ensures the proper execution of "predelete" and "delete" hooks that other modules may rely on for cleanup operations.

function my_module_uninstall() {
  $entity_type_manager = \Drupal::entityTypeManager();
  $entity_storage = $entity_type_manager->getStorage('your_entity_type');

  // Replace 'your_entity_id' with the ID of the configuration entity you want to delete.
  $entity = $entity_storage->load('your_entity_id');
  if ($entity) {
    $entity->delete();
  }
}

Replace 'your_entity_type' and 'your_entity_id' with the appropriate values for your configuration entities. This approach ensures that other modules' hooks will be triggered, providing a more accurate cleanup process.

Method 6: Deleting Configuration Objects with Contributed Modules

Some contributed modules provide an easy way to delete configuration objects. One example is the Config Delete module, which you can find at https://www.drupal.org/project/config_delete. After installing the module, you can use it to delete configuration objects without writing any custom code. Remember to always clear your cache after deleting configuration objects to avoid potential issues. You can use the 'drush cr' command to clear the cache when using Drush.
