Deptrac: A Comprehensive Guide
Introduction to Deptrac
Deptrac is a powerful static code analysis tool designed specifically for PHP projects. It plays a crucial role in the development environment by helping developers not only communicate and visualize architectural decisions but also enforce them effectively. By using Deptrac, you can define your project's architectural layers clearly and establish rules to manage them, ensuring organized and maintainable code structures.
Purpose and Functionality
Imagine working on a complex project with several modules, bundles, or extensions. Deptrac allows you to ensure these components remain independent of each other. This independence is vital for enhancing reusability and simplifying modifications without affecting unrelated parts of the project. Deptrac confirms adherence to architectural guidelines during the development process by checking for violations through static analysis.
Continuous Integration and Visualization
To maintain these architectural rules, Deptrac can seamlessly integrate into your Continuous Integration (CI) pipeline. This integration is especially beneficial when reviewing pull requests, as it ensures that new code contributions comply with your established architectural standards. Moreover, Deptrac offers visualization options through formats like Graphviz and Mermaidjs, allowing you to see an illustrative representation of your layers, rules, and any violations.
Getting Started with Deptrac
Setting up Deptrac in your PHP project is straightforward. It's available via Composer, a widely used PHP dependency manager. By running a simple command in your terminal, you can install Deptrac in your development environment:
composer require --dev qossmic/deptrac
Once installed, Deptrac requires a configuration file, written in YAML or PHP, housed typically in your project's root directory under the name deptrac.yaml. This configuration file defines the architectural layers and the rules governing them. To simplify the initial setup, Deptrac provides a command to generate a template configuration:
vendor/bin/deptrac init
After setting up the configuration file, analyzing your code is a breeze. Execute the following command to ensure your project remains architecturally sound:
vendor/bin/deptrac
It’s essential to have PHP version 8.1 or higher to run Deptrac. However, projects using older PHP versions can still be analyzed, provided they use a compatible version of nikic/php-parser.
