Magento 2 has been improved so much ever since it was released in 2010 with a bunch of more features and a brand new architecture. However, some tasks still need to be done by hand. Here we shall discuss the fine adjustments – the Magento 2 tips, to smoothen the customers’ experience at Magento 2 stores.

First thing is to activate the Developer mode: get SSH and use the following command:

The next step is to go to Stores → Configuration → Advanced → Developer. As you have set the Developer mode active, the Developer tab will appear. Any changes for better Magento 2 performance you make on this tab shall be carried out in other modes as well. 


Now in the Developer tab, we shall look at these Magento 2 tips:

  • CSS Settings: You are supposed to turn on the two CSS settings: Merge CSS Files and Minify CSS Files. 

To get back to the Production Mode, use this line: 

php bin/magento deploy:mode:set production

If you wish to ensure that you have returned to Production Mode, then this one:

php bin/magento deploy:mode:show

It then gets back to you:

Current application mode: production.

Tip #2. Javascript Quote Escape and URL Site Escaper

Tip #3. Use of Varnish Caching


It’s certain that you usually switch between the Production and Developer Modes. There comes this Magento 2 tip which is not available in Default nor Production Mode, but Developer only. 

In the natural Magento 2 setting, a built-in Magento catching tool administers the cache management, yet we have a better choice here for you. 

Navigate to Configuration in Stores, then choose Advanced → System, expand the Full Page Cache section. Now you are to disable Use system value in Catching Application, then select Varnish Cache (Recommended). Lastly, do not forget to click the Save Config button for applying changes. 

Tip #4. Object Order Restoration On Order Confirmation Page


For retrieving order objects like ID or details on order-success page in Magento 2 performance, first, you need to get to the Checkout Session:

* Checkout session
* @var \Magento\Checkout\Model\Session
protected $_checkoutSession;
* @param \Magento\Framework\View\Element\Template\Context $context
* @param \Magento\Sales\Model\Order $salesOrderFactory
* @param \Magento\Checkout\Model\Session $checkoutSession
public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Sales\Model\Order $salesOrderFactory,
        \Magento\Checkout\Model\Session $checkoutSession,
        array $data = []
    ) {
        $this->_checkoutSession = $checkoutSession;
        parent::__construct($context, $data);


Next, you retrieve the order you want with this code snippet:

* Retrieve current order
* @return \Magento\Sales\Model\Order
public function getOrder()
   $orderId = $this->_checkoutSession->getLastOrderId();
   return $this->_salesFactory->load($orderId);

Alternatively, this Magento 2 tip also suggests you can use the following different code:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$orderId = $objectManager->create('\Magento\Checkout\Model\Session')
$order = $objectManager->create('\Magento\Sales\Model\Order')

Tip #5. Product Object and Request Object Retrievation

It is possible to fetch back not only product object page but request object as well with these 2 code snippets:

For product object:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('\Magento\Catalog\Model\Product')

For request object:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('\Magento\Framework\App\Request\Http')
                            ->getParam('product', 0);  

Tip #6. Removal of Redundant Extensions


This one is the last Magento 2 tip, but also the easiest and most important one for better Magento 2 performance. A research used to show that one-third of the extensions installed in a store are left untouched and just take up space and resources. 

One important thing to notice is that there is a real difference between disabling and deleting an extension. Setting an extension inactive means that it is still present, and slows down the website due to the cron time and space taken in the module directory. Therefore, the best choice is to remove unused extensions.

In SSH, get to your Magento install section. Let’s just call the extension you want to get rid of as ‘Extensiontodelete’, then apply these code:

php bin/magento module:disable Extensiontodelete --clear-static-content
php bin/magento setup:upgrade
cd app/code/Extensiontodelete/
rm -rf Extensiontodelete

The above command has certainly disabled the useless extension and cleared its static content. Later, get Magento revise itself and clear cache. Lastly, go to the extension folder and delete the disabled extension above. Repeat these steps with other unused extensions and you will get your site spotless.
