Settings::getSiteConfig() 

\nn\t3::Settings()->getSiteConfig($request = NULL); 

Get site configuration. This is the configuration that has been defined in the YAML files in the /sites folder since TYPO3 9. Some of the settings can also be set via the "Sites" page module.

In the context of a MiddleWare, the site may not yet be parsed / loaded. In this case, the $request from the MiddleWare can be passed to determine the site.

$config = \nn\t3::Settings()->getSiteConfig();
$config = \nn\t3::Settings()->getSiteConfig( $request );
