Understanding Drupal: Core Concepts and Architecture

Before diving into development, it’s essential to understand what makes Drupal unique and how its architecture works.

What Sets Drupal Apart as a CMS

Drupal distinguishes itself from other content management systems through several key characteristics:

Flexibility and Extensibility: Unlike more rigid CMS platforms, Drupal allows developers to customize virtually every aspect of the system.
Scalability: From small personal blogs to enterprise-level applications serving millions of users, Drupal scales efficiently to meet diverse requirements.
Security: With a dedicated security team and strict coding standards, Drupal maintains a strong security posture that makes it suitable for government and enterprise applications.
Community-Driven Development: The vast Drupal community contributes thousands of modules and themes, constantly improving and extending the platform’s capabilities.
API-First Architecture: Modern Drupal embraces a decoupled approach, making it ideal for creating content hubs that serve multiple frontends through robust APIs.

According to recent industry statistics, Drupal powers approximately 14% of the top 10,000 websites as of 2025, demonstrating its continued relevance in the enterprise space.

Drupal’s Architectural Overview

Understanding Drupal’s architecture is fundamental to effective development:

Drupal Core: The foundation of any Drupal installation, providing essential functionality and APIs.
Modules: Extensions that add new features or modify existing functionality.
- Core Modules: Included with Drupal but can be enabled/disabled as needed
- Contributed Modules: Created by the community and available for download
- Custom Modules: Developed specifically for a particular project
Themes: Control the visual presentation and user experience.
- Core Themes: Basic themes included with Drupal
- Contributed Themes: Community-created themes
- Custom Themes: Tailored designs for specific projects
Configuration System: Manages site settings and states in a version-controllable format.
Content Entities: Structured content types like nodes, users, taxonomy terms, and comments.
Field System: Allows adding custom fields to any entity type, creating flexible content structures.
Plugin System: Provides a standardized way to create reusable components with swappable implementations.
Services & Dependency Injection: Modern PHP architecture that promotes maintainable, testable code.

In 2025, Drupal’s architecture continues to evolve toward a more decoupled, API-first approach, with 68% of enterprise Drupal implementations now utilizing some form of decoupled architecture.

Evolution of Drupal: From 7 to 10 and Beyond

Drupal has undergone significant transformations over its releases:

Drupal 7: Still in use but reaching end-of-life, characterized by its procedural programming approach.
Drupal 8: Introduced modern PHP practices, Symfony components, and object-oriented programming.
Drupal 9: Focused on removing deprecated code and updating dependencies while maintaining API compatibility with Drupal 8.
Drupal 10: Released with updated dependencies, improved frontend tools, and enhanced developer experience.
Drupal 11: Currently in development, focusing on improved content workflows, enhanced decoupled capabilities, and modern JavaScript integration.

As of 2025, industry surveys indicate that 82% of new Drupal projects are built on Drupal 10, with the remaining sites primarily on Drupal 9 with plans to upgrade.

Setting Up Your Drupal Development Environment

A properly configured development environment is essential for efficient Drupal development.

Local Development Options

Several approaches exist for local Drupal development:

Container-Based Solutions:
- DDEV: A Docker-based development environment that’s become the standard for Drupal development in 2025.
- Lando: Another popular Docker-based option with strong Drupal integration.
- Docker4Drupal: A lightweight Docker Compose setup specifically for Drupal.
Virtual Machine Solutions:
- Drupal VM: A VM for Drupal development, though less popular than container options in 2025.
Native Setup:
- Installing Apache/Nginx, PHP, MySQL/PostgreSQL, and other requirements directly on your machine.

According to 2025 developer surveys, 76% of Drupal developers now use container-based solutions, with DDEV being the most popular choice at 43% adoption.

Step-by-Step Environment Setup Using DDEV

DDEV provides a straightforward setup process:

Install Prerequisites:
- Docker Desktop (for Windows/Mac) or Docker Engine (for Linux)
- Git
- Composer

Install DDEV:

# For macOS with Homebrew

brew install ddev/ddev/ddev

# For Windows with Chocolatey

choco install ddev

# For Linux

curl -LO https://raw.githubusercontent.com/ddev/ddev/master/scripts/install_ddev.sh

bash install_ddev.sh

Create a New Drupal Project:

mkdir my-drupal-project

cd my-drupal-project

ddev config --project-type=drupal10 --docroot=web --create-docroot

ddev composer create drupal/recommended-project

ddev composer require drush/drush

Install Drupal:

ddev drush site:install –account-name=admin –account-pass=admi

Start the Development Server:

ddev start

Access Your Site:
- Web: https://my-drupal-project.ddev.site
- Admin: https://my-drupal-project.ddev.site/user/login

This streamlined setup process takes approximately 10-15 minutes and provides a complete development environment with all necessary tools.

Essential Development Tools

Beyond the basic environment, several tools enhance the Drupal development workflow:

Composer: Package management for PHP dependencies.
Drush: Command-line interface for managing Drupal sites.
Git: Version control system essential for collaborative development.
Xdebug: Debugging tool for PHP that integrates with IDEs.
Node.js and npm: Required for modern frontend workflows.
Gulp/Webpack: Task runners and bundlers for frontend assets.
IDE/Code Editor: Popular options include:
- PHPStorm: The most comprehensive IDE with Drupal-specific features
- Visual Studio Code: Lightweight editor with excellent Drupal extensions
- Sublime Text: Minimalist option focused on speed
Browser Developer Tools: For frontend debugging and performance analysis.

Recent Drupal developer productivity studies show that using the right toolset can reduce development time by up to 40%, with integrated debugging and automated testing tools providing the greatest efficiency gains.

Drupal Development Fundamentals

Understanding key Drupal concepts is essential before diving into hands-on development.

The Drupal Project Structure

A typical Drupal 10 project follows this structure:

project-root/

├── config/              # Configuration export files

├── vendor/              # Composer dependencies

├── web/                 # Drupal docroot

│   ├── core/            # Drupal core

│   ├── modules/

│   │   ├── contrib/     # Downloaded modules

│   │   └── custom/     # Custom modules

│   ├── profiles/        # Installation profiles

│   ├── sites/

│   │   ├── default/     # Site-specific settings

│   │   │   └── files/   # User-uploaded files

│   │   └── simpletest/  # Testing environments

│   └── themes/

│       ├── contrib/     # Downloaded themes

│       └── custom/     # Custom themes

├── composer.json        # Project dependencies

└── drush/               # Drush commands and configuration

Understanding this structure helps navigate the codebase efficiently and place custom code in the appropriate locations.

Drupal’s Hook System

Although largely replaced by object-oriented approaches in modern Drupal, hooks remain important:

What Are Hooks?: Functions that allow modules to “hook into” Drupal’s core functionality.
Common Hooks in Drupal 10:
- hook_form_alter(): Modify forms
- hook_entity_*(): Interact with entities
- hook_theme(): Register theme implementations
- hook_cron(): Execute code during cron runs
- hook_update_N(): Define database updates

Implementing Hooks:

function mymodule_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id) {

  if ($form_id == 'article_node_form') {

    $form['title']['widget'][0]['value']['#description'] = 'Enter a descriptive title.';

  }

}

While hooks are still used, modern Drupal development increasingly favors event subscribers, plugins, and services over traditional hooks.

The Entity API

Entities are the foundation of Drupal’s content architecture:

Content Entities: Data intended for display, like:
- Nodes (basic content)
- Users
- Comments
- Taxonomy terms
- Media
Configuration Entities: Settings that define site behavior, such as:
- Content types
- Views
- Image styles
- Role permissions

Working with Entities in Code:

/ Load a node

$node = \Drupal\node\Entity\Node::load(1);

// Create a new node

$node = \Drupal\node\Entity\Node::create([

  'type' => 'article',

  'title' => 'New Article',

  'body' => [

    'value' => 'Article content',

    'format' => 'full_html',

  ],

]);

$node->save()

In 2025, Drupal’s entity API continues to mature, with enhanced support for complex field types and improved performance for entity operations.

Drupal’s Database API

For direct database operations, Drupal provides a robust abstraction layer:

Static Queries:

$query = \Drupal::database()->select('node_field_data', 'n')

  ->fields('n', ['nid', 'title'])

  ->condition('n.status', 1)

  ->condition('n.type', 'article')

  ->orderBy('n.created', 'DESC')

  ->range(0, 10);

$results = $query->execute()->fetchAll()

Dynamic Queries:

$query = \Drupal::entityQuery('node')

  ->condition('status', 1)

  ->condition('type', 'article')

  ->sort('created', 'DESC')

  ->range(0, 10);

$nids = $query->execute();

Database Transactions:

$transaction = \Drupal::database()->startTransaction();

try {

  // Database operations

  // ...

}

catch (\Exception $e) {

  $transaction->rollBack();

  throw $e;

}

While direct database queries are sometimes necessary, best practices in 2025 Drupal development favor using entity API operations when possible for better maintainability and compatibility.

Drupal Module Development

Modules extend Drupal’s functionality through custom code.

Module Structure and Essential Files

A basic custom module requires these components:

Module Directory: /web/modules/custom/mymodule/

Information File (mymodule.info.yml):

name: My Module

type: module

description: 'A custom module example.'

core_version_requirement: ^10

package: Custom

Module File (mymodule.module):

<?php

/**

 * @file

 * Contains hook implementations for My Module.

 */

/**

 * Implements hook_theme().

 */

function mymodule_theme() {

  return [

    'my_template' => [

      'variables' => ['content' => NULL],

    ],

  ];

}

Services File (mymodule.services.yml):

services:

  mymodule.my_service:

    class: Drupal\mymodule\MyService

    arguments: ['@entity_type.manager'

Routing File (mymodule.routing.yml):

mymodule.example:

  path: '/mymodule/example'

  defaults:

    _controller: '\Drupal\mymodule\Controller\MyController::content'

    _title: 'Example Page'

  requirements:

    _permission: 'access content'

This basic structure provides the foundation for extending Drupal’s functionality through custom code.

Creating Controllers and Routes

Controllers handle HTTP requests and return responses:

Define a Route:

# mymodule.routing.yml

mymodule.hello:

  path: '/hello/{name}'

  defaults:

    _controller: '\Drupal\mymodule\Controller\HelloController::content'

    _title: 'Hello'

    name: 'World'

  requirements:

    _permission: 'access content'

Create the Controller:

// src/Controller/HelloController.php

namespace Drupal\mymodule\Controller;

use Drupal\Core\Controller\ControllerBase;

class HelloController extends ControllerBase {

  public function content($name) {

    return [

      '#markup' => $this->t('Hello, @name!', ['@name' => $name]),

    ];

  }

}

Access Control:

// Add to the controller class

public function access() {

  return \Drupal\Core\Access\AccessResult::allowedIfHasPermission(

    $this->currentUser(), 'view hello content'

  );

Modern Drupal development increasingly uses route controllers for structured page building rather than hook-based approaches.

Working with Services and Dependency Injection

Services provide reusable functionality across your application:

Define a Service:

# mymodule.services.yml

services:

  mymodule.data_processor:

    class: Drupal\mymodule\Service\DataProcessor

    arguments: ['@entity_type.manager', '@logger.factory']

Create Service Class:

// src/Service/DataProcessor.php

namespace Drupal\mymodule\Service;

use Drupal\Core\Entity\EntityTypeManagerInterface;

use Drupal\Core\Logger\LoggerChannelFactoryInterface;

class DataProcessor {

  protected $entityTypeManager;

  protected $loggerFactory;

  public function __construct(

    EntityTypeManagerInterface $entity_type_manager,

    LoggerChannelFactoryInterface $logger_factory

  ) {

    $this->entityTypeManager = $entity_type_manager;

    $this->loggerFactory = $logger_factory->get('mymodule');

  }

  public function processData($data) {

    $this->loggerFactory->notice('Processing data');

    // Process data

    return $processed_data;

  }

}

Using the Service:

// In a controller

$data_processor = \Drupal::service('mymodule.data_processor');

$result = $data_processor->processData($input);

// With dependency injection

protected $dataProcessor;

public function __construct(DataProcessor $data_processor) {

  $this->dataProcessor = $data_processor;

}

public static function create(ContainerInterface $container) {

  return new static(

    $container->get('mymodule.data_processor')

  );

}

Service-oriented architecture is now the standard in Drupal development, with 92% of custom modules in 2025 utilizing services and dependency injection.

Creating Custom Forms

Forms are built using the Form API:

Basic Form Structure:

// src/Form/ExampleForm.php

namespace Drupal\mymodule\Form;

use Drupal\Core\Form\FormBase;

use Drupal\Core\Form\FormStateInterface;

class ExampleForm extends FormBase {

  public function getFormId() {

    return 'mymodule_example_form';

  }

  public function buildForm(array $form, FormStateInterface $form_state) {

    $form['name'] = [

      '#type' => 'textfield',

      '#title' => $this->t('Name'),

      '#required' => TRUE,

    ];

    $form['email'] = [

      '#type' => 'email',

      '#title' => $this->t('Email'),

      '#required' => TRUE,

    ];

    $form['actions']['submit'] = [

      '#type' => 'submit',

      '#value' => $this->t('Submit'),

    ];

    return $form;

  }

  public function validateForm(array &$form, FormStateInterface $form_state) {

    if (strlen($form_state->getValue('name')) < 3) {

      $form_state->setErrorByName('name', $this->t('Name must be at least 3 characters.'));

    }

  }

  public function submitForm(array &$form, FormStateInterface $form_state) {

    $this->messenger()->addStatus($this->t('Form submitted successfully.'));

    // Process form values

  }

}

Form Route:

# mymodule.routing.yml

mymodule.example_form:

  path: '/mymodule/form'

  defaults:

    _form: '\Drupal\mymodule\Form\ExampleForm'

    _title: 'Example Form'

  requirements:

    _permission: 'access content'

Configuration Forms:

// src/Form/SettingsForm.php

class SettingsForm extends ConfigFormBase {

  protected function getEditableConfigNames() {

    return ['mymodule.settings'];

  }

  public function getFormId() {

    return 'mymodule_settings_form';

  }

  public function buildForm(array $form, FormStateInterface $form_state) {

    $config = $this->config('mymodule.settings');

    $form['api_key'] = [

      '#type' => 'textfield',

      '#title' => $this->t('API Key'),

      '#default_value' => $config->get('api_key'),

    ];

    return parent::buildForm($form, $form_state);

  }

  public function submitForm(array &$form, FormStateInterface $form_state) {

    $this->config('mymodule.settings')

      ->set('api_key', $form_state->getValue('api_key'))

      ->save();

    parent::submitForm($form, $form_state);

  }

}

Form API continues to be a core strength of Drupal, with modern UX enhancements like conditional fields and AJAX support making it more powerful in 2025.

Creating Custom Plugins

Plugins provide swappable implementations of functionality:

Plugin Types:
- Block plugins
- Field types, widgets, and formatters
- Views plugins
- Migration plugins

Block Plugin Example:

// src/Plugin/Block/ExampleBlock.php

namespace Drupal\mymodule\Plugin\Block;

use Drupal\Core\Block\BlockBase;

/**

 * @Block(

 *   id = "mymodule_example",

 *   admin_label = @Translation("Example Block"),

 *   category = @Translation("Custom")

 * )

 */

class ExampleBlock extends BlockBase {

  public function build() {

    return [

      '#markup' => $this->t('Hello from a custom block!'),

    ];

  }

}

Field Formatter Example:

// src/Plugin/Field/FieldFormatter/CustomFormatter.php

namespace Drupal\mymodule\Plugin\Field\FieldFormatter;

use Drupal\Core\Field\FormatterBase;

use Drupal\Core\Field\FieldItemListInterface;

/**

 * @FieldFormatter(

 *   id = "mymodule_custom",

 *   label = @Translation("Custom Formatter"),

 *   field_types = {

 *     "text",

 *     "text_long"

 *   }

 * )

 */

class CustomFormatter extends FormatterBase {

  public function viewElements(FieldItemListInterface $items, $langcode) {

    $elements = [];

    foreach ($items as $delta => $item) {

      $elements[$delta] = [

        '#markup' => '<div class="custom-format">' . $item->value . '</div>',

      ];

    }

    return $elements;

  }

}

The plugin system has matured in Drupal 10, with improved developer experience through better discovery and more consistent APIs.

Drupal Theme Development

Themes control the visual presentation and user experience of a Drupal site.

Modern Theming Approaches

Drupal theming has evolved significantly:

Component-Based Theming:
- Building reusable, modular UI components
- Integration with design systems
- Pattern libraries like Pattern Lab or Storybook
Starter Themes:
- Olivero: Drupal 10’s modern, accessible default theme
- Claro: Admin theme with improved UX
- Bootstrap: Integration with the Bootstrap framework
- Foundation: Based on the Foundation framework
Frontend Frameworks Integration:
- React
- Vue.js
- Alpine.js
- Tailwind CSS

In 2025, 63% of new Drupal themes use component-based architecture, with 47% integrating with a JavaScript framework for enhanced interactivity.

Theme Structure and Essential Files

A basic theme requires these components:

Theme Directory: /web/themes/custom/mytheme/

Information File (mytheme.info.yml):

name: My Theme

type: theme

description: ‘Custom theme for my site.’

core_version_requirement: ^10

base theme: olivero

libraries:

– mytheme/global-styling

regions:

header: Header

primary_menu: ‘Primary menu’

content: Content

sidebar: Sidebar

footer: Footer

Libraries File (mytheme.libraries.yml):

global-styling:

css:

theme:

css/style.css: {}

js:

js/script.js: {}

dependencies:

– core/drupal

Theme Settings (config/install/mytheme.settings.yml):

logo:

path: ‘themes/custom/mytheme/logo.svg’

features:

node_user_picture: true

comment_user_picture: true

comment_user_verification: true

Template Files:
- templates/page.html.twig
- templates/node/node–article.html.twig
- templates/block/block–system-branding-block.html.twig

This structure provides the foundation for customizing your site’s appearance and user experience.

Twig Templating in Drupal

Twig is Drupal’s templating engine:

Basic Syntax:

{# Comment #}

{{ variable }} {# Print a variable #}

{% if condition %} {# Control structure #}

Content

{% endif %}

Common Twig Functions and Filters:

{{ content|render }} {# Render a render array #}

{{ ‘Hello’|t }} {# Translate a string #}

{{ path(‘entity.node.canonical’, {‘node’: node.id}) }} {# Generate a URL #}

{{ file_url(node.field_image.entity.uri.value) }} {# Get a file URL #}

Template Suggestions: Drupal uses a pattern for template naming that allows for increasingly specific templates:
- page.html.twig (all pages)
- page–front.html.twig (front page only)
- page–node.html.twig (all node pages)
- page–node–article.html.twig (article nodes only)

Debug Mode: Enable Twig debug mode in development.services.yml:

parameters:

twig.config:

debug: true

auto_reload: true

cache: false

In 2025, Twig remains the standard for Drupal theming, though the integration with JavaScript frameworks continues to grow for more dynamic interfaces.

Responsive and Accessible Theming

Modern Drupal themes prioritize responsiveness and accessibility:

Responsive Design Approaches:
- Mobile-first CSS using media queries
- Fluid layouts with flexible grids
- Responsive images using <picture> element or srcset
- Viewport-based units (vw, vh)
Accessibility Best Practices:
- Semantic HTML5 markup
- ARIA roles and attributes
- Sufficient color contrast (WCAG 2.1 AA compliant)
- Keyboard navigation support
- Screen reader compatibility

Implementing in Drupal:

{# Responsive image example #}

{% if content.field_image|render %}

</picture>

{% endif %}

Drupal 10 core themes (Olivero and Claro) set high standards for accessibility, with WCAG 2.1 AA compliance built-in, establishing accessibility as a baseline requirement for modern Drupal themes.

Advanced Drupal Development

As you progress in Drupal development, several advanced topics become important.

Decoupled (Headless) Drupal

Decoupled Drupal separates the frontend and backend:

Approaches to Decoupling:
- Fully Decoupled: Drupal serves only as a content API
- Progressively Decoupled: Traditional Drupal with JavaScript enhancements
- Hybrid Decoupled: Mix of traditional and decoupled approaches
API Options:
- JSON:API: Built into Drupal core
- GraphQL: Available through contributed modules
- RESTful Web Services: Core module for simple REST endpoints
Frontend Technologies:
- React, Vue.js, Angular for single-page applications
- Next.js, Gatsby, Nuxt.js for static site generation
- Native mobile apps consuming Drupal APIs

In 2025, 56% of enterprise Drupal sites use some form of decoupling, with JSON:API being the most popular approach at 68% adoption among decoupled implementations.

Drupal Commerce Development

Building e-commerce functionality with Drupal Commerce:

Commerce Components:
- Products and variations
- Orders and carts
- Payment gateways
- Shipping methods
- Taxes and promotions
Custom Development Areas:
- Product types and attributes
- Checkout flows
- Payment gateway integrations
- Order workflows

Code Example: Custom Product Type:

// In a custom module’s .module file

function mymodule_entity_bundle_info_alter(&$bundles) {

$bundles[‘commerce_product’][‘subscription’] = [

‘label’ => t(‘Subscription’),

‘description’ => t(‘Subscription product with recurring billing.’),

];

}

Drupal Commerce has become increasingly popular for complex B2B e-commerce systems, with a 37% growth in enterprise adoption since 2023.

Performance Optimization

Optimizing Drupal for performance is critical for user experience:

Caching Strategies:
- Page cache for anonymous users
- Dynamic Page Cache for authenticated users
- BigPipe for personalized content
- Views caching for complex queries
Database Optimization:
- Query optimization and indexing
- Entity query caching
- Database connection pooling
Frontend Performance:
- Aggregation of CSS and JavaScript
- Lazy loading of images and iframes
- Critical CSS implementation
- Modern image formats (WebP, AVIF)
Infrastructure Optimization:
- Content Delivery Networks (CDNs)
- Redis or Memcached for caching
- Container-based hosting
- Edge computing integration

Performance benchmark studies in 2025 show that properly optimized Drupal 10 sites can achieve sub-second load times and Time to Interactive metrics, even for complex applications.

Automated Testing

Quality assurance through automated testing:

Testing Types:
- Unit tests for isolated functions
- Kernel tests for subsystems
- Functional tests for user interactions
- JavaScript tests for browser interactions
Testing Framework:
- PHPUnit for PHP tests
- Nightwatch for JavaScript tests
- Behat for behavior-driven development

Example PHPUnit Test:

// tests/src/Unit/ExampleTest.php

namespace Drupal\Tests\mymodule\Unit;

use Drupal\Tests\UnitTestCase;

use Drupal\mymodule\Service\Calculator;

class CalculatorTest extends UnitTestCase {

public function testAddition() {

$calculator = new Calculator();

$result = $calculator->add(2, 3);

$this->assertEquals(5, $result);

}

Continuous Integration:
- GitHub Actions
- GitLab CI
- CircleCI
- Tugboat for visual regression testing

According to 2025 development best practices reports, projects with comprehensive test coverage experience 71% fewer production issues and 43% faster development cycles for new features.

Adherence to standards improves code quality and collaboration:

Drupal Coding Standards:
- PSR-4 for class autoloading
- PSR-12 for code style
- Drupal-specific conventions
- Use PHP_CodeSniffer with Drupal standard
Documentation Best Practices:
- PHPDoc comments for classes and methods
- README.md files for modules and themes
- Code examples for complex functions
- Inline comments for non-obvious logic
Automated Tools:
- PHPCS for code standards checking
- PHPCBF for automatic fixing
- PHPStan for static analysis
- Drupal Check for deprecation checks

Development teams that enforce coding standards report 34% fewer bugs and 47% faster onboarding for new developers.

Security Best Practices

Security remains a top priority in Drupal development:

Security Principles:
- Least privilege principle
- Defense in depth
- Input validation and sanitization
- Regular security updates
Common Vulnerabilities to Prevent:
- Cross-site scripting (XSS)
- SQL injection
- Cross-site request forgery (CSRF)
- Remote code execution
Drupal-Specific Security Measures:
- Proper use of Text Formats and allowed HTML tags
- Sanitization with Html::escape() and Xss::filter()
- Private file system for sensitive uploads
- Twig autoescape for template output

Security in Code:

// Unsafe

$output = ‘<div>’ . $user_input . ‘</div>’;

// Safe

use Drupal\Component\Utility\Html;

$output = ‘<div>’ . Html::escape($user_input) . ‘</div>’;

According to security audits in 2025, sites following Drupal security best practices experience 82% fewer successful attack attempts compared to those with custom security implementations.

Continuous Learning and Community Involvement

The Drupal ecosystem evolves rapidly, making ongoing learning essential:
