Can I use this with API Platform?

Yes, the skill includes specific implementation patterns for using DTOs as input and output classes within API Platform resource operations.

Why should I separate Input and Output DTOs?

Separating them allows you to have strict validation rules for incoming data while providing custom formatting and filtered fields for outgoing responses.

How does this skill handle database persistence?

It provides patterns for Doctrine Embeddables, allowing Value Objects to be stored across multiple table columns while remaining a single, cohesive object in PHP.

Does it support modern PHP features?

Absolutely, it leverages PHP 8.1+ features like readonly classes and promoted properties to ensure strict immutability and concise code.

What is the benefit of using Value Objects in Symfony?

Value Objects ensure domain integrity by encapsulating validation and logic within immutable objects, preventing invalid data states from entering your application.

API Development

Implements immutable Value Objects and Data Transfer Objects for clean, validated domain modeling in Symfony applications.

This skill provides Claude with domain-specific patterns for designing robust Symfony architectures using Value Objects and DTOs. It emphasizes DDD principles such as immutability, self-validating constructors, and PHP 8.1+ readonly properties. By leveraging this skill, developers can automate the creation of complex domain concepts like Money, Email, and Address, while ensuring data integrity through Doctrine Embeddables and clear separation of concerns with API-ready Input and Output DTOs.
