Add below content in this file.

File Path=app/code/Mage2db/John/Controller/Index/Index.php

<?php
namespace Mage2db\John\Controller\Index;

use Magento\Backend\App\Action\Context;

class Index extends \Magento\Framework\App\Action\Action
{
	
    /**
     * @var \Magento\Framework\App\Cache\TypeListInterface
     */
    protected $_cacheTypeList;

    /**
     * @var \Magento\Framework\App\Cache\StateInterface
     */
    protected $_cacheState;

    /**
     * @var \Magento\Framework\App\Cache\Frontend\Pool
     */
    protected $_cacheFrontendPool;

    /**
     * @var \Magento\Framework\View\Result\PageFactory
     */

     *
     */
    public function execute()
    {
	    $this->resultPage = $this->resultPageFactory->create();  
        return $this->resultPage;
    }
}

Step [5] – Create Helper.php under your module.

Add below content in this file.

File Path=app/code/Mage2db/John/Helper/Data.php

<?php
namespace  Mage2db\John\Helper;
use Magento\Store\Model\StoreManagerInterface;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
	protected $storeManager; 

	/**
     * @param \Magento\Framework\App\Helper\Context $context
     */
	public function __construct
	(
   \Magento\Framework\App\Helper\Context $context,   StoreManagerInterface $storeManager
	) 
	{
	    $this->storeManager = $storeManager;	
		parent::__construct($context);
	}
	  
	public function getStoreManagerData()
    {
          //return $storeUrl = $this->storeManager->getStore()->getBaseUrl();
         // get Store Url without index.php
        return $storeUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_WEB);
           // get Link Url of store
          // $storeLinkUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_DIRECT_LINK);
         // get media Base Url
        //  $storeMediaUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
      // get Static content Url
      // $storeStaticUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_STATIC);
    }
}

Step [6] – Create Block under your module.

	) 
	{
	    $this->storeManager = $storeManager;	
		parent::__construct($context);
	}
	  
	public function getStoreManagerData()
    {
          //return $storeUrl = $this->storeManager->getStore()->getBaseUrl();
         // get Store Url without index.php
        return $storeUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_WEB);
           // get Link Url of store
          // $storeLinkUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_DIRECT_LINK);
         // get media Base Url

      // get Static content Url
      // $storeStaticUrl = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_STATIC);
    }
	  
}

Step [7] – Create view under your module.

under view folder create layout & template file

Layout File

app/code/Mage2db/John/view/frontend/layout/john_index_index.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
 <body>		
   <referenceContainer name="main.content">			
<block class="Mage2db\John\Block\Index\Index" name="index_index" template="index/index.phtml"> </block>
  </referenceContainer>      
 </body>
</page>

Template File

app/code/Mage2db/John/view/frontend/templates/index/index.phtml

<?php

   //Template index phtml 
  echo"<BR> Base URL===".$baseurl= $block->getbaseurldata();
        
?>		

Step [8] – Finally your custom module for Base URL, Media URL, Link URL etc . has been created

Run the following below commands at your Magento 2 root directory

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento indexer:reindex
php bin/magento cache:clean
php bin/magento cache:flush

Run below URL

https://mage2db.com/john/index/index

Magento 2 One-Page Checkout, all required checkout information will be put on a single page. When On-Page Checkout is enabled, the entire checkout process takes place on a single page. Each section of the checkout information is expanded as needed Accordingly, Shoppers won’t be directed to another page to complete their checkout process, It is much more time-saving than the normal checkout process.

On-Page Checkout is enabled by default, if the Store Owner wants to integrate another third party checkout extension, it is necessary to disable One-Page Checkout.

There are following below Admin setting required to disable One-Page Checkout

Step [1] – Go STORES > Configuration, redirects Configuration section.

Step [2] – Click on Left Panel Sales > Checkout

Step [3] – Once Right Panel (Checkout Options) expanded

Step [4] – Set Enable On-Page Checkout to No, after unchecked Use system value

There are 7 Products Types in Magento 2

1. Simple Product
2. Configurable Product
3. Grouped Product
4. Bundle Product
5. Virtual Product
6. Downloadable Product
7. Gift Card Product

[1] – Simple Product ::

The Simple Product is a physical item, most popular product type of a store, this product do not have attribute (selectable variations) as size, color, weight etc.
This product has a single SKU (Stock Keeping Unit)

[2] – Configurable Product ::

The configurable product is a combination of simple products, each simple product has its own attribute (size, color, weight etc) & SKU as well as own stock Inventory.

Example ::

Why Need Configurable Product

customers browse products in any store & getting multiple similar products, they will get annoyed & negatively rankings effect on search engine (Google, Yahoo, Bing etc.), that is why need to create configurable product.

Here Total products variations =12, if not creating configurable product, need to show 12 products on store, its not good presentation of products.

Total Simple Products Variations is 12 = One Configurable Product

[3] – Grouped Product ::

Grouped Product is a combination of multiple single(standalone) product, each product characteristics or are related to each other and presented on one page.

These single(standalone) product as Simple Product or Virtual Product or Downloadable Product etc.

These single(standalone) products are often related to each other and grouped by theme, season, or business purpose.

Each single product from Grouped Product can be purchased separately or group.

Example::

Customer can purchase grouped product Set of Sprite Yoga Traps

There are three set of Sprite Yoga Traps with various foot & prices

Customers can purchase any set of Sprite Yoga Traps as their need

[a] Sprite Yoga Traps 6 foot – 14.00 US$

[b] Sprite Yoga Traps 8 foot – 17.00 US$

[c] Sprite Yoga Traps 10 foot – 21.00 US$

Why Need Grouped Product

Customers can shop all their needed products at once instead of visiting separate product detail pages for shopping, This improve customers satisfaction and keep confident coming back to your store as well as Store business growth, That is why need to create Grouped Product

[4] – Bundle Product ::

Bundle Product is combination of various Simple products or Virtual Product and can be customized as per their need while shopping.

Magento 2, other product types have a button Add to cart in common, while in case bundle products have a different button named Customize and Add to Cart, This enables customers to customize the product using a list of options before adding to the cart.

Example ::

This bundled product Customize Spite Yoga Companion Kit appears with four individual items as

• Sprite Stasis Ball
• Sprite Foam Yoga Brick
• Sprite Yoga Strap
• Sprite Foam Roller.

Each product has several options for customers to select (product variations)

[5] – Virtual Product ::

Virtual Product do not have physical or digital entries. There are multiple products as non-tangible items such as memberships, services, warranties, or subscriptions and digital downloads of books, music, videos, OTT (Netflix, Amazon Prime Video) etc.. These products cannot be shipped or downloaded from the link. This is a great way to sell services or intellectual products such as warranties, subscription or updates.

Example ::

[6] – Downloadable Products ::

Downloadable Product have downloadable counterpart. There are multiple products as Software, eBooks, E-Learning, Fonts, Courses, Graphics & digital art, Video Game, MP3, MP4, Tickets etc. Downloadable product does not allow selecting a shipping method at checkout, simply because shipping is not needed and client receives purchased entity right away.

Example ::

[7] Gift Card (Adobe Commerce):: Gift Card products are applicable by Adobe Commerce.

“A Gift Card is a form of payment that can be used to do shopping at online stores or physical stores.”

Adobe Commerce 2.x supports three Gift Card

1. Physical Gift Cards [Printed Gift Cards]:: [Printed Gift Cards] to be mailed(Posted) recipients street address or postal address or shipping address or physical mail not by Email ID
   Physical Gift Cards can be mass produced in advance and embossed with unique codes.
2. Virtual Gift Cards:: A Virtual Gift Card has “No Stock Quantity” and is always “In Stock Quantity”. It is always required recipients Email ID.
3. Combined Gift Card = It is combination of Physical Gift Card & Virtual Gift Card

_{Adobe Commerce 2.x allow 7 Type Products including Gift Card Products}

_{Magento Open Source 2.x allow 6 Type Products}

Difference Between Virtual and Downloadable Products

What is CSRF and CSRF Token

Cross-site request forgery (CSRF or XSRF) , also know as One Click Attack, is a web security vulnerability that allows an Attacker / Hacker to attack on web application & to induce authenticated users to perform actions that they do not intend to perform. 

Cross Site Request Forgery = Cross Site + Request Forgery

Cross-Site Request Forgery Working Model

Attackers using multiple social engineering technique to attack by using CSRF or XSRF, This technique working as The victim into clicking a URL that having maliciously crafted or set of maliciously crafted , unauthorized request for a specific Web application, Then user’s browser sending this maliciously crafted or set of maliciously crafted request to a targeted Web application. The request also includes any credentials information to the particular website (user session or cookies). Id use as from of an active session with a targeted Web application, the application response this new request as an authorized request submitted by the authorized user.
Finally, The attacker successfully exploited the Web application infected with CSRF vulnerability.

There are multiple below cases, to attack CSRF

• Submitting or deleting a record Form
• Submitting a transaction Form
• Purchasing a product Form
• Changing a password Form
• Sending a message Form
• Contact Form

Application Prevent Against Cross-Site Request Forgery Attack

Preventing CSRF Attack, requires the inclusion of an unpredictable token in the body or URL of each HTTP request. Such tokens should at a minimum be unique per user session as well as be unique per request.

• Properly validate submission form before the relevant action is executed
• The preferred option is to include the unique token in a hidden field. The unique token can also be included in the URL itself, or a URL parameter.
• Check Referrer field of each request.
• Use Captcha on all critical page.

CSRF is a common form of attack and has ranked several times in the OWASP Top Ten (Open Web Application Security Project).

Magento 2 prohibits the direct use of the ObjectManager in code because it hides the real dependencies of a class

Magento 2.x Coding Standard Rules / Regulations

The main reason, the Object Manager directly is that direct use of the Object Manager causes the extension not to be installable in compiled production mode.

Never call the object manager directly because the Magento 2 Framework handles this automatically

By 2017, The Magento 2 Marketplace runs a compile and install test on all extensions by using properly Magento 2 Coding Standard. If your extension uses the Object Manager directly, it will fail these tests and be rejected from the Marketplace until you resolve this problem and reupload.

How To Setup Magento 2.x Coding Standard

Magento 2 Logs having ecommerce store information records for the analysis purpose, as each functionality of ecommerce store either working fine or not, Its both status store in log files One of the most common examples of such events is the error log.
