PDS Skeleton by Example: A Standard for File and Folder Structure

This article explores the php-pds/skeleton and uses it to build a small Laravel package that maps FAQ pages to exceptions. The PDS (Package Development Standards) skeleton promotes a consistent file and folder structure for PHP packages, improving organization and maintainability.

Key Concepts:

• PDS Skeleton: A standard for organizing PHP project files and folders, enhancing code readability and maintainability. It provides a consistent structure including directories for source code, tests, documentation, and configuration. It's designed to be flexible and adaptable to individual project needs.
• PSR Standards: While PDS focuses on file structure, PSR standards concentrate on coding style and conventions. They are complementary and often used together.

Package Functionality:

The example package maps exceptions thrown in a Laravel application to relevant FAQ pages, providing users with helpful information when errors occur. The final code is available on GitHub.

Building the Package:

The process involves:

1. Downloading the Skeleton: The php-pds/skeleton package is downloaded and extracted. Alternatively, it can be generated using Composer: composer require --dev pds/skeleton && ./vendor/bin/pds-skeleton generate.

2. Updating composer.json: The composer.json file is modified to define the package name, description, dependencies, and autoloading. The pds/skeleton is included as a require-dev dependency for tracking and command-line tools.

3. Git Initialization: The project is initialized as a Git repository, committed, and pushed to a remote repository on GitHub.

4. Directory Structure: The package adheres to the PDS skeleton structure, including src/, tests/, config/, resources/, public/, docs/, and other relevant directories.

5. Code Implementation: The core logic involves creating models (src/Models/Faq.php), a service provider (src/Providers/FaqProvider.php), a repository (src/Repositories/FaqRepository.php), and renderers for web and API responses. A database migration (resources/migrations/2014_10_12_000000_create_faq_table.php) and a view (resources/views/faq.blade.php) are also created.

6. Testing: Unit tests are written in the tests/ directory.

7. Documentation: A README.md file provides an overview, while more detailed documentation resides in the docs/ directory. A LICENSE file specifies the license (e.g., MIT). A CONTRIBUTING.md file outlines contribution guidelines. A CHANGELOG.md tracks changes between releases.

8. Validation: The pds-skeleton validate command verifies adherence to PDS standards.

Conclusion:

Using a standardized skeleton like php-pds/skeleton significantly improves code organization and collaboration. While other skeletons exist, PDS provides a widely applicable and verifiable structure for PHP package development. The article encourages discussion on the importance of standardized folder structures in software development.
