Working with configs

// Read config with machine name 'system.site' 
// and get property 'name'
// initial configuration stored 
//    at 'core/modules/system/config/install/system.site.yml'
// sync (when enabled) - 
//    at 'config/sync/system.site.yml'
$this->config('system.site')->get('name');

$frontPage = $this->configFactory->get('system.site')
  ->get('page.front');

Configuration

States

\Drupal::state()->set('key','value');

$values = [
  'key' => 'value',
  'key2' => 'value2'
];
\Drupal::state()->setMultiple($values);

\Drupal::state()->delete('key');

Updates

/**
 * Convert syslog.settings.facility to an integer.
 */
function syslog_update_8400() {
  $config = \Drupal::configFactory()->getEditable('syslog.settings');
  $facility = (int) $config->get('facility');
  $config->set('facility', $facility)->save(TRUE);
}
