Magento include a base .gitignore file with the Magento Open Source project repository. See the latest Magento .gitignore file. If you need to add a file that is in the .gitignore list, you can use the -f (force) option when staging a commit:

Caching plays an essential role in improving the page load time. In this article, I want to show you five blocks cache in Magento 2, or five approaches to caching, and when and how to use them. Interestingly, this article will cover both full page and block cache. Let’s explore each type of block cache together!

In case, cache_lifetime of the block is set to a number greater than 0, the block is cacheable

to cache any block, you need to override this function 

You can set the mode via command line

php bin/magento indexer:set-mode {realtime|schedule} [indexer-name]

“realtime” is equal to “Update on Save” and “schedule” is equal to “Update by Schedule”.

Add the following line to your CSS file:

.opc-summary-wrapper{

    display:none;

}

Goto following directory

vendor/magento/module-checkout/view/frontend/web/js/model

And open the file step-navigator.js

Copy this file to your working theme directory.

Edit the function getActiveItemIndex in step-navigator.js You will get 0,1 etc when console.log(activeIndex);

 

RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]

the best way to do do this is using the below method

$objectManager =   \Magento\Framework\App\ObjectManager::getInstance();
$productR =      $objectManager ->create('\Magento\Catalog\Api\ProductRepositoryInterface');
$product = $productR->get('product_sku');
$product->cleanCache();
$this->_eventManager->dispatch('clean_cache_by_tags', ['object' => $product]);

you need of course to follow the DI to implement this code, I just used this quick way to make it easy to understand

Using Object Manager

$storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
$websiteId = $storeManager->getStore()->getWebsiteId();
 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerRepository = $objectManager->create('Magento\Customer\Api\CustomerRepositoryInterface');
 
// load customer info by email
$customer = $customerRepository->get('[email protected]', $websiteId);
 
// load customer info by id    
$customer = $customerRepository->getById(1);
 
// Update customer Info
$cust

Magento profiler can help you with the store performance tuning before the store release or during the exploitation.
The old UI for enabling/disabling the profiler is not available in Magento 2 and the profiler is disabled by default.
To enable one of the profiler formats mentioned above, you can edit .htaccess (a configuration file for Apache Web Server software):

    Choose one of the next expressions:
