New Registrar Feature

What is this CodeIgniter\Shield\Config namespace?

It is just sample code. It is a sample namespace.
Probably in your context, a namespace that you use.

Any namespace may define implicit registrars by using the Config/Registrar.php file. These files are classes whose methods are named for each configuration class you wish to extend.

So I could create a app/Config/Registrar.php file like this:

PHP Code:

<?php // $Id$

namespace App\MyConfig;

use App\Filters\{DOSFilter, HostFilter, LoginSecurityFilter};
use App\Validation\NcrsEbnRules;

class Registrar
{
  public static function Filters(): array
  {
    return [
      'aliases' => [
        'host' => HostFilter::class,
        'dos' => DOSFilter::class,
        'loginsecurity' => LoginSecurityFilter::class,
      ],
      'globals' => [
        'before' => [
          'host',
          'dos',
          'loginsecurity',
        ],
      ],
      'methods' => [
        'post' => ['csrf'],
      ],
    ];
  }

  public static function Validation(): array
  {
    return [
      'ruleSets' => [
        NcrsEbnRules::class,
      ],
    ];
  }
} 


This works!

Simpler is always better
