Value Objects Bundle Laravel Package

Product Decisions This Supports

• Domain-Driven Design (DDD) Adoption: Enables structured modeling of business logic via value objects (e.g., Money, Email, DateRange), aligning with DDD principles for cleaner domain layers.
• Type Safety & Validation: Reduces runtime errors by enforcing immutable, validated objects (e.g., Email with regex checks) early in the pipeline.
• Roadmap for Legacy Systems: Justifies modernizing Symfony 2.x/3.x monoliths by introducing DDD patterns without full framework upgrades.
• Build vs. Buy: Avoids reinventing value-object logic (e.g., custom Money classes) while maintaining consistency across microservices or modules.
• Use Cases:
  • E-commerce (e.g., ProductPrice, InventoryQuantity).
  • SaaS (e.g., UserEmail, SubscriptionPeriod).
  • Financial systems (e.g., CurrencyAmount, TransactionId).

When to Consider This Package

• Adopt if:

  • Your team uses Symfony 2.x–5.x and needs lightweight DDD integration.
  • You prioritize immutable, validated data over ORM entities (e.g., Doctrine).
  • Your domain requires rich types (e.g., Email, Percentage) but lacks time for custom implementations.
  • You’re migrating from procedural code to DDD and need a low-risk starting point.

• Look elsewhere if:

  • You’re on Symfony 6+ (use native DDD tools or symfony/ux-dnd for modern patterns).
  • Your stack is non-Symfony (e.g., Laravel, Node.js—use native packages like moneyphp/money).
  • You need complex behavior (e.g., event sourcing) beyond simple value objects.
  • Your team lacks DDD familiarity (requires buy-in for design changes).

How to Pitch It (Stakeholders)

For Executives: "This bundle lets us model business data (e.g., prices, emails) as self-validating objects, reducing bugs and making code more maintainable. For example, an Email object will reject invalid formats at creation—no more runtime errors in user registration. It’s a lightweight upgrade for our Symfony apps that aligns with modern DDD practices, saving dev time on boilerplate while improving reliability."

For Engineers: *"The cubicmushroom/value-objects-bundle wraps nicolopignatelli/valueobjects, giving us immutable, validated objects (e.g., Money, Email) with minimal setup. Key benefits:

• No ORM bloat: Value objects live outside Doctrine, keeping domain logic pure.
• Symfony 2–5 compatibility: Works with legacy systems without forcing upgrades.
• Extensible: Add custom objects (e.g., ProductSku) by extending base classes. Tradeoff: Limited to Symfony; for new projects, consider Symfony 6’s native DDD tools."*
