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:

Nice and clean one 

Magento2 Indexing Mode 

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):
