Magento 2 Development

To load custom mini-libraries with short popular global functions in Magento 2, run the following code:

<type name='\Magento\Framework\AppInterface'>
            <plugin
                        name='Df\Framework\AppInterfacePlugin'
                        type='Df\Framework\AppInterfacePlugin'
            />
</type>

<plugin

name='Df\Framework\AppInterfacePlugin'

type='Df\Framework\AppInterfacePlugin'

</type>

<?php
namespace Df\Framework;
use \Magento\Framework\AppInterface;
class AppInterfacePlugin {
            /**
            * @see \Magento\Framework\AppInterface::launch()
            * @param AppInterface $subject
            * @return array
            */
            public function beforeLaunch(AppInterface $subject) {
                        // Place your custom initialization code here.
                        return [];
            }
}

<?php

namespace Df\Framework;

use \Magento\Framework\AppInterface;

class AppInterfacePlugin {

/**

* @see \Magento\Framework\AppInterface::launch()

* @param AppInterface $subject

* @return array

public function beforeLaunch(AppInterface $subject) {

// Place your custom initialization code here.

return [];

}

In case of console apps, do everything as follows:

<event name='store_collection_load_before'>
            <observer
                        name='Df\Core\Boot'
                        instance='Df\Core\Boot'
                        method='storeCollectionLoadBefore'
            />
</event>

<observer

name='Df\Core\Boot'

instance='Df\Core\Boot'

method='storeCollectionLoadBefore'

</event>

<?php
namespace Df\Core;
use \Magento\Framework\Event\Invoker\InvokerDefault;
use \Magento\Framework\Event\Observer as _O;
class Boot {
            /**
            * @used-by InvokerDefault::_callObserverMethod()
            * @param _O $o
            * @return void
            */
            public function storeCollectionLoadBefore(_O $o) {
                        if (!self::$_done && 'cli' === PHP_SAPI) {
                                    self::run();
                        }
            }
            // other code here...
}
