2: Set Up Your Development Environment

2.1 Use a Virtual Host

Configure Apache or Nginx to serve your Magento instance.

• For Apache:

     
      ServerName yourdomain.com  
      DocumentRoot /var/www/html/magento2
  
       
          AllowOverride All 
      
  
      ErrorLog ${APACHE_LOG_DIR}/magento2_error.log  
      CustomLog ${APACHE_LOG_DIR}/magento2_access.log combined  
   

  Enable the configuration:

  sudo a2ensite magento2.conf

  sudo systemctl restart apache2

• For Nginx: Create a server block configuration in /etc/nginx/sites-available/magento2:

 server {  
      listen 80;  
      server_name yourdomain.com;  
      root /var/www/html/magento2;

      location / {  
          index index.php;  
          try_files $uri $uri/ /index.php?$query_string;  
      }

      location ~ \.(php|phtml)$ {  
          fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;  
          include fastcgi_params;  
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
          fastcgi_param MAGE_RUN_CODE default;  
          fastcgi_param MAGE_RUN_TYPE store;  
      } 
  } 

Enable the configuration:

sudo ln -s /etc/nginx/sites-available/magento2 /etc/nginx/sites-enabled/

sudo systemctl restart nginx

2.2 Set Up Xdebug

• Install Xdebug to debug your Magento code:

  sudo apt install php-xdebug

• Add the following to php.ini:

  xdebug.mode=debug

  xdebug.start_with_request=yes

  xdebug.client_port=9003

  xdebug.client_host=127.0.0.1

• Restart PHP:

  sudo systemctl restart php7.4-fpm

2.3 Set Up Git

• Initialize Git in your Magento directory for version control:

  git init

  git add

  git commit -m "Initial commit"

3: Learn Magento 2 Architecture

3.1 Modular Structure

Magento 2 divides features into modules. Each module is self-contained and follows a specific directory structure:

• app/code: Contains custom modules

• etc: Stores configuration files

• Model: Handles data logic

• Controller: Handles user requests

• View: Manages Magento 2 layouts, templates, and styles

3.2 Dependency Injection (DI)

Magento uses DI to manage object dependencies. Instead of hardcoding dependencies, they are injected through constructors or XML configuration. It improves flexibility and testability.

Example

class Example {  
    `private $dependency;

public function __construct(DependencyClass $dependency) {  
        $this->dependency = $dependency;  
    }  
}

3.3 Observers and Plugins

• Observers: Listen to specific events and execute custom logic.

• Plugins: Modify or extend methods in existing classes without overriding.

3.4 Layouts and Templates

Layouts control the structure of pages using XML files. Templates contain HTML and PHP for rendering content. Together, they define the front-end look.

4: Master Command Line Tools

4.1 Common CLI Commands

• Clear Cache: php bin/magento cache:clean

• Compile Code: php bin/magento setup:di:compile

• Deploy Static Content: php bin/magento setup:static-content:deploy

• Reindex Data: php bin/magento indexer:reindex

4.2 Using CLI for Module Management

• Enable or disable modules using the CLI:

  php bin/magento module:enable Vendor_ModuleName

  php bin/magento module:disable Vendor_ModuleName

4.3 Setup Upgrade

• After making changes, run:

  php bin/magento setup:upgrade

It updates the database schema and applies necessary changes.

5: Develop and Customize Themes

5.1 Understand the Theme Structure

Themes are located in the app/design/frontend. The structure includes:

• etc/view.xml: Configuration for images and styles

• web/css: Contains CSS and LESS files

• templates: Stores PHTML template files

5.2 Create a Custom Theme

• Create a directory: app/design/frontend/Vendor/theme

• Add theme.xml:

  <theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
<title>Custom Theme</title>
<parent>Magento/luma</parent>
</theme>

• Register the theme in registration.php:

  \Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::THEME,
'frontend/Vendor/theme',
__DIR__
);

• Deploy the theme: php bin/magento setup:static-content:deploy

6: Build Custom Modules

6.1 Create a Basic Module

• Create the module folder: app/code/Vendor/ModuleName

• Add registration.php:

  \Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Vendor_ModuleName',
__DIR__
);

• Add module.xml in the etc folder:

  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Vendor_ModuleName" setup_version="1.0.0" />
</config>

• Enable the module:

  php bin/magento module:enable Vendor_ModuleName

  php bin/magento setup:upgrade

7: Debug and Test

7.1 Enable Developer Mode

Switch Magento to developer mode: php bin/magento deploy:mode:set developer

7.2 Check Logs

• Magento logs errors and issues in:

  var/log/system.log

  var/log/exception.log

7.3 Use Xdebug

Debug your code step-by-step using Xdebug and an IDE like PHPStorm.

7.4 Run Functional Tests

• Magento provides functional tests: vendor/bin/mftf run:tests

  It validates your store's functionality in different scenarios.
