Deptrac

Deptrac is a static code analysis tool for PHP applications that helps manage and enforce architectural rules in a codebase. It works by analyzing your project’s dependencies and verifying that these dependencies adhere to predefined architectural boundaries. The main goal of Deptrac is to prevent tightly coupled components and ensure a clear, maintainable structure, especially in larger or growing projects.

Key features of Deptrac:

1. Layer Definition: It allows you to define layers in your application (e.g., controllers, services, repositories) and specify how these layers are allowed to depend on each other.
2. Violation Detection: Deptrac detects and reports when a dependency breaks your architectural rules, helping you maintain cleaner boundaries between components.
3. Customizable Rules: You can customize the rules and layers based on your project’s architecture, allowing for flexibility in different application designs.
4. Integration with CI/CD: It can be integrated into CI pipelines to automatically enforce architectural rules and ensure long-term code quality.

Deptrac is especially useful in maintaining decoupling and modularity, which is crucial in scaling and refactoring projects. By catching architectural violations early, it helps avoid technical debt accumulation.
