Request Dto Mapper Bundle Laravel Package

Product Decisions This Supports

• Accelerated API Development: Reduces boilerplate for request/response DTOs (Data Transfer Objects) in Laravel controllers, enabling faster iteration on API endpoints.
• Enhanced Validation & Error Handling: Leverages Symfony Validator (optional) for robust input validation, with violations stored as request attributes for consistent error responses.
• Architectural Flexibility: Supports decoupled validation logic via events (PostDtoValidationEvent) and customizable data extraction, aligning with clean architecture principles.
• Roadmap for Microservices: Ideal for modularizing request/response handling in microservices or monolithic apps with strict separation of concerns.
• Build vs. Buy: Eliminates the need to reinvent DTO/validation infrastructure, reducing technical debt compared to custom solutions.

When to Consider This Package

• Adopt if:
  • Your team uses Laravel for APIs and needs standardized DTO handling.
  • You prioritize validation-driven development with minimal boilerplate.
  • Your roadmap includes microservices or modular controllers.
  • You’re open to Symfony Validator (or already use it) for validation rules.
• Look elsewhere if:
  • Your stack relies heavily on non-Laravel frameworks (e.g., Symfony, Express).
  • You need real-time validation (e.g., frontend-first forms) without backend DTOs.
  • Your team prefers manual request parsing (e.g., for legacy codebases).
  • You require advanced features like nested DTOs with custom resolvers (consider api-platform or spatie/laravel-data).

How to Pitch It (Stakeholders)

For Executives: "This package cuts API development time by 30%+ by automating DTO validation and request parsing. It’s a drop-in solution for Laravel APIs, reducing bugs from manual validation while supporting our microservices roadmap. Low risk—just add a PHP attribute to controllers."

For Engineering: *"v1.0.0 stabilizes DTO handling with:

• Zero-config validation: Annotate controllers with [Dto] attributes.
• Event-driven hooks: Extend validation logic via PostDtoValidationEvent.
• Symfony Validator integration: Optional but powerful for complex rules.
• Error consistency: Violations stored as request attributes for unified API responses. Tradeoff: Breaking change from argument resolvers (migrate via kernel events). Unit tests included—ready for CI/CD."*
