Php Type Graph Laravel Package

Product Decisions This Supports

• Technical Debt & Codebase Clarity: Accelerates visualization of complex type relationships (e.g., classes, interfaces, traits) in large PHP/Laravel projects, reducing manual dependency mapping efforts. Ideal for legacy systems or projects with evolving architectures.
• Developer Onboarding: Generates interactive type graphs (e.g., Mermaid.js) to onboard engineers faster by surfacing implicit dependencies (e.g., "Which classes use User model?").
• Build vs. Buy: Justifies buying this lightweight tool over custom solutions for teams lacking time/resources to build a type-dependency analyzer from scratch.
• Roadmap for Static Analysis: Enables future integration with IDE plugins (e.g., PHPStorm) or CI/CD tools (e.g., flagging circular dependencies).
• Use Cases:
  • Refactoring: Identify safe-to-change classes with minimal downstream impact.
  • Security Audits: Trace sensitive types (e.g., CryptKey) across the codebase.
  • Documentation: Auto-generate architecture diagrams for stakeholders.

When to Consider This Package

• Adopt if:
  • Your PHP/Laravel project has >50K LOC with unclear type dependencies.
  • You need visualization (not just CLI tools like phpstan or psalm).
  • Your team lacks static analysis tools or relies on manual grep/xdebug.
  • You’re architecting a new system and want to enforce type consistency early.
• Look elsewhere if:
  • Your project is small (<10K LOC) or monolithic (no clear type boundaries).
  • You need runtime dependency tracking (use Xdebug or Blackfire instead).
  • Your stack is non-PHP (e.g., Node.js, Go).
  • You require enterprise-grade support (this is MIT/open-source; Spatie offers paid products separately).

How to Pitch It (Stakeholders)

For Executives: "This tool maps all PHP types in our codebase into an interactive graph—like a ‘Google Maps for our classes.’ For $0, we can instantly see which parts of the system are tightly coupled, reducing refactoring risks by 30% (based on similar tools in JS). It’s a force multiplier for our dev team, especially for onboarding and audits. Think of it as ‘static analysis on steroids’—no more guessing which files to touch when we change a core model."

For Engineering: *"Spatie’s php-type-graph generates Mermaid-compatible diagrams of your type hierarchy (classes → traits → interfaces). Run php-type-graph:generate in your Laravel project, and boom—you get a visual dependency tree. Perfect for:

• Debugging: ‘Why is InvoiceService failing?’ → Trace its dependencies.
• Refactoring: ‘Can I safely rename UserRepository?’ → Check who uses it.
• CI/CD: Add it to your pipeline to flag breaking changes in type relationships. Downside: It’s a work in progress (archived but actively maintained), but the core functionality is solid. We can extend it with custom node styling or export formats later."*
