How to properly use AssetManager/ClientScript?

Question

Yii

How to use these classes in the controller to create groups of files, which are then loaded in the view?
This is something like the minify library, where we first create groups in groupsConfig, and then pull through ?g=groupName.
I saw the minScript extension - it uses minify, but I didn’t stick it how to do it. It just did a redirect. Can you tell me how to prepare it?
If it is possible to do all this without crutches / extensions, I will be grateful for the advice.
There is nothing in the documentation, except for the description of properties/methods. Thanks, my IDE also shows ...

Yii has a CClientScript component that is responsible for including script and css files. This component has a packages property , with which we can configure the packages of our JavaScript / CSS files, specify dependencies for them, and then connect these packages in the view using one method.
Example from config:

'components' => array( 
    'clientScript' => array(
        'packages' => array(
            'item' => array(
                'baseUrl' => 'js',
                'js' => array('item.js'),
                'depends' => array('jquery'),
            ),
            'filter' => array(
                'baseUrl' => 'js',
                'js' => array('filter.js'),
                'depends' => array('jquery'),
            ),
        ),
    ),
),

Here we have defined 2 packages (item and filter), each consisting of 1 JavaScript file. Both packages depend on a package that is part of the Yii core - jQuery. Thus, by connecting these packages to the view, the CClientScript component will first connect jQuery and only then the files from our package.
We connect our packages to the view in the following way:

Yii::app()->clientScript->registerPackage('item');
