Overview

This is a Drupal extension scaffold template for creating contributed modules or themes. The project provides a complete development environment with CI configuration, testing setup, and deployment automation for publishing to Drupal.org.

Development Commands

HARD RULE - use the provided command wrappers, never the tool binaries directly. When make or ahoy exposes a command for a task, use that command; do not call the underlying binary directly. Each wrapper chdirs into build/ and runs the tool with the config, plugins, and environment that CI uses, so a raw invocation from the repository root silently diverges from CI - it can pass locally while CI fails (or vice versa), or crash outright when a relative path resolves against the wrong directory. If no wrapped command covers what you need, extend the make / ahoy target rather than making a one-off raw call; if that is not feasible, stop and ask.

Run each tool through its make wrapper, never the binary directly:

• PHPCS / PHPCBF: make lint / make lint-fix - never vendor/bin/phpcs or vendor/bin/phpcbf.

• PHPStan: make lint - never vendor/bin/phpstan.

• Rector: make lint (dry-run) / make lint-fix - never vendor/bin/rector.

• Twig CS Fixer: make lint / make lint-fix - never vendor/bin/twig-cs-fixer.

• ESLint / Stylelint: make lint / make lint-fix - never npx eslint or npx stylelint.

• CSpell: make lint - never npx cspell.

• PHPUnit: make test / make test-unit / make test-kernel / make test-functional - never vendor/bin/phpunit.

• Jest: make test-javascript - never npx jest.

• Drush: make drush <command> - never build/vendor/bin/drush directly.

Run each tool through its ahoy wrapper, never the binary directly:

• PHPCS / PHPCBF: ahoy lint / ahoy lint-fix - never vendor/bin/phpcs or vendor/bin/phpcbf.

• PHPStan: ahoy lint - never vendor/bin/phpstan.

• Rector: ahoy lint (dry-run) / ahoy lint-fix - never vendor/bin/rector.

• Twig CS Fixer: ahoy lint / ahoy lint-fix - never vendor/bin/twig-cs-fixer.

• ESLint / Stylelint: ahoy lint / ahoy lint-fix - never npx eslint or npx stylelint.

• CSpell: ahoy lint - never npx cspell.

• PHPUnit: ahoy test / ahoy test-unit / ahoy test-kernel / ahoy test-functional - never vendor/bin/phpunit.

• Jest: ahoy test-javascript - never npx jest.

• Drush: ahoy drush <command> - never build/vendor/bin/drush directly.

Build and Environment Management

Using Make (default):

• make build - Complete build (stop → assemble → start → provision)
• make assemble - Assemble codebase with dependencies
• make start - Start PHP development server
• make stop - Stop development server
• make provision - Install/provision Drupal site
• make reset - Clean build directory and logs (aliases: make delete, make destroy)

Using Ahoy (alternative):

• ahoy build - Complete build process
• ahoy assemble - Assemble codebase
• ahoy start - Start development server
• ahoy provision - Provision Drupal site

Code Quality

Linting:

• make lint - Run all linting tools
• make lint-fix - Auto-fix coding standards violations

• ahoy lint - Run all linting tools
• ahoy lint-fix - Auto-fix coding standards violations

Testing:

• make test - Run all tests

• make test-unit - Run unit tests only
• make test-kernel - Run kernel tests only
• make test-functional - Run functional tests only

• make test-functional-javascript - Run FunctionalJavascript tests (uses the local Chrome by default; set WEBDRIVER_BACKEND=selenium for Docker)

• make test-javascript - Run JavaScript unit tests with Jest (alias: make test-js)

• make browser-start - Start the browser for FunctionalJavascript tests (local Chrome by default; set WEBDRIVER_BACKEND=selenium for Docker)
• make browser-stop - Stop the browser

• ahoy test - Run all tests

• ahoy test-unit - Run unit tests only
• ahoy test-kernel - Run kernel tests only
• ahoy test-functional - Run functional tests only

• ahoy test-functional-javascript - Run FunctionalJavascript tests (uses the local Chrome by default; set WEBDRIVER_BACKEND=selenium for Docker)

• ahoy test-javascript - Run JavaScript unit tests with Jest (alias: ahoy test-js)

• ahoy browser-start - Start the browser for FunctionalJavascript tests (local Chrome by default; set WEBDRIVER_BACKEND=selenium for Docker)
• ahoy browser-stop - Stop the browser

Drupal Commands

• make drush <command> - Run Drush commands
• make login - Get one-time login link

• ahoy drush <command> - Run Drush commands
• ahoy login - Get one-time login link

Diagnostics

• make info - Print a read-only summary of PHP/Drupal/Composer/Drush/Node versions, webserver host/port (with source), XDebug state, build directory, database path, and active profile. (alias: make describe)

• ahoy info - Print a read-only summary of PHP/Drupal/Composer/Drush/Node versions, webserver host/port (with source), XDebug state, build directory, database path, and active profile. (alias: ahoy describe)

Project Structure

Key Directories:

• src/ - Extension source code (services, forms, etc.)

• tests/src/ - PHPUnit tests (Unit/, Kernel/, Functional/)

• config/schema/ - Configuration schema definitions
• build/ - Assembled Drupal codebase (symlinked extension)
• .devtools/ - Build and deployment scripts used by CI
• scripts/ - Custom lifecycle hooks: post-assemble (assemble-*.sh), post-provision (provision-*.sh), post-start (start-*.sh), and pre-stop (stop-*.sh). Run automatically during each phase in lexicographic order; non-zero exit aborts the parent. Excluded from distribution archives via .gitattributes

Template Files (before init):

• your_extension.* - Template extension files
• YourExtensionService.php - Main service class template

Architecture

• Service-based architecture: Main functionality in services registered via *.services.yml
• Configuration-driven: Uses Drupal configuration system with schema validation
• Test coverage: Unit, kernel, and functional test examples provided
• Form integration: Admin forms in src/Form/ for configuration

Environment Variables

• DRUPAL_VERSION - Target Drupal version (e.g., 10, 11, 11@alpha)
• WEBSERVER_HOST - Development server host (default: localhost)
• WEBSERVER_PORT - Development server port. Auto-discovered from range 8000-8099 and written to .env if not already set

• WEBDRIVER_BACKEND - FunctionalJavascript WebDriver backend: chromedriver (default, drives the locally installed Chrome with no Docker) or selenium (Docker container)
• WEBDRIVER_PORT - Port for the WebDriver endpoint (both backends). Auto-discovered from 4444 and written to .env if not already set, so several projects can run FunctionalJavascript tests simultaneously. The endpoint in phpunit.xml is the default for port 4444; tests reach the resolved port because the FunctionalJavascript base class rewrites the port in MINK_DRIVER_ARGS_WEBDRIVER from this variable, so FunctionalJavascript tests must extend that base class (or export their own MINK_DRIVER_ARGS_WEBDRIVER)

• GITHUB_TOKEN - GitHub API token to avoid rate limits
• DEBUG - Set to 1 to stream the full output of the underlying commands (Composer, npm, Drush). By default this output is suppressed and shown only when a command fails

Development Workflow

1. Run php init.php to customize template for your extension
2. Build environment: make build or ahoy build
3. Develop your extension code in src/
4. Check standards: make lint or ahoy lint
5. Run tests: make test or ahoy test
6. Access site at http://localhost:8000

Code Quality Tools

• CSpell: Spell checking across the codebase (config at .cspell.json)

• PHPCS: Drupal and DrupalPractice standards

• PHPStan: Static analysis with Drupal extensions

• Rector: Automated refactoring and deprecation fixes

• Twig CS Fixer: Twig template formatting

CI/CD Support

• GitHub Actions: .github/workflows/test.yml and deployment
• CircleCI: .circleci/config.yml configuration
• Matrix testing: PHP 8.3-8.5, Drupal 10-11
• Automated deployment: Mirror to Drupal.org on release

Important Notes

• The build/ directory contains the assembled Drupal site
• Extension files are symlinked from root into build/web/modules/custom/ (module) or build/web/themes/custom/ (theme)
• SQLite database created in /tmp/site_[EXTENSION_NAME].sqlite
• All quality tools run from within build/ directory

Updating the scaffold

When the user asks to update this project's scaffold (e.g. "update scaffold"), fetch the update skill from GitHub into the local .claude/skills/ directory, then invoke it:

1. Create the target directory if it does not exist:

   mkdir -p .claude/skills/update-consumer-drupal-extension-scaffold

2. Download the skill:

   curl -sSL https://raw.githubusercontent.com/AlexSkrypnyk/drupal_extension_scaffold/1.x/.scaffold/skills/update-consumer-drupal-extension-scaffold/SKILL.md -o .claude/skills/update-consumer-drupal-extension-scaffold/SKILL.md

3. Invoke the update-consumer-drupal-extension-scaffold skill and follow its steps.

The skill directory is git-ignored - it is fetched on demand and not committed to the project.
