base\Module $controllerMap

Mapping from controller ID to controller configurations. Each name-value pair specifies the configuration of a single controller. A controller configuration can be either a string or an array. If the former, the string should be the fully qualified class name of the controller. If the latter, the array must contain a class element which specifies the controller's fully qualified class name, and the rest of the name-value pairs in the array are used to initialize the corresponding controller properties. For example,

[
  'account' => 'app\controllers\UserController',
  'article' => [
     'class' => 'app\controllers\PostController',
     'pageTitle' => 'something new',
  ],
]
