What problem does it solve?

This Skill introduces the concept of Value Objects to address the issue of primitives carrying domain meaning and the lack of type safety in domain code.

Core Features & Use Cases

  • Immutable Types: Encapsulates domain concepts as immutable types with validation at construction and value-based equality.
  • Self-Validating: Ensures that only valid instances are created, reducing runtime errors.
  • Use Case: Replace primitive types with Value Objects for domain entities like Money, EmailAddress, and UserId to prevent common bugs related to type mismatches and invalid data.

Quick Start

Implement a Value Object for money with validation for currency and amount.
