If yarn start or yarn watch is throwing any errors, try git pull, and then yarn install

Create an advancedqueue

create a file like advancedqueue.advancedqueue_queue.ipc_merge_sync.yml in modules/custom/ipc_syncdb/config/install

id: ipc_merge_sync
label: 'IPC Merge Sync'
backend: database
backend_configuration: {}
processor: cron
processing_time: 180
locked: true

then import it with drush cim --partial --source=/home/ipc/www/ipc/docroot/modules/custom/ipc_syncdb/config/install

For a multiple-value field, to add the value to the end of the list, use the following code.

$node->field_code_used_by[] = ['target_id' => $user_id];

For a single use

$group_content1->group_roles->target_id = $role_id 

  use Drupal\Core\Site\Settings;

    $api_key = Settings::get('ipc_merge');
    $key = \Drupal::request()->server->get('HTTP_X_API_KEY');

then in settings.local.php or settings.php you would put

  $settings['ipc_merge'] = 'XXXXXXXXXXXXXXXXXXXXXXXX';

\Drupal::config('ipc_syncdb.settings')->get('transaction_api_log_level');

or

use Drupal\Core\Config\ConfigFactoryInterface;
$config = $this->configFactory->get('ipc_syncdb.settings');
 $requestParams->logLevel = $config->get('transaction_api_log_level');

This is working code, as a workaround in using entityquery:

look in theme.liquid to add the javascript to the head
look in header.liquid to find the header HTML in the theme.

Put this in their config:

{
  "send_stats": false,
  "translate_images": false,
  "language_selector" : [
            {
                "U" : "U",
                "T" : "T",
                "I" : "OneLinkJS_langSel",
                "C" : "C",
                "position" : "first"
            }
        ]
}

and the one liner in the head of the document.

 \Drupal::logger('ipc_order_sync')->notice('Adding the following order to the enqueJob @order_id
         with transaction id of @transaction_id',
          [
            '@order_id' => $order['order_id'],
            '@transaction_id' => $order['transaction_id'],
          ]);

In your settings.php:

$settings['foo'] = 'bar';

In your code:

use Drupal\Core\Site\Settings;

Settings::get('foo', 'mydefaultvalue');
