Common Value Objects Laravel Package

Product Decisions This Supports

• Domain-Driven Design (DDD) Adoption: Enables consistent implementation of value objects across microservices or monolithic applications, aligning with DDD principles for better domain modeling.
• Type Safety & Validation: Reduces runtime errors by enforcing constraints (e.g., UUID formats, non-empty strings) at the object level, improving data integrity.
• Reusable Infrastructure: Accelerates development by providing pre-built, validated value objects (e.g., Gender, DateTimeRange, Slug), reducing boilerplate code.
• API/Backend Standardization: Facilitates consistent data handling across services, especially in polyglot persistence or multi-service architectures.
• Security Compliance: Includes specialized objects like StrongPasswordField to enforce security policies (e.g., password strength) without custom logic.
• Roadmap for Composite Value Objects: Paves the way for integrating apie/composite-value-objects later, enabling complex domain objects (e.g., Address as a composite of Street, City, PostalCode).
• Build vs. Buy: Avoids reinventing value objects (e.g., UUID validation, slug generation) while maintaining flexibility to extend or customize classes.

When to Consider This Package

• Avoid if:
  • Your team lacks PHP/DDD experience; the package assumes familiarity with value objects and interfaces like IdentifierInterface.
  • You need highly customized value objects (e.g., domain-specific enums/rules) that aren’t covered by the package’s offerings.
  • Your project uses non-PHP backends (e.g., Node.js, Go) or requires cross-language compatibility.
  • You prioritize existing adoption (0 stars/dependents may signal unproven reliability; evaluate the Apie monorepo for maturity).
• Consider if:
  • You’re building a PHP/Laravel application with DDD principles or need standardized value objects.
  • Your domain requires strict data validation (e.g., UUIDs, slugs, passwords) without custom logic.
  • You want to reduce technical debt by leveraging battle-tested components (even if early-stage).
  • Your team is open to MIT-licensed open-source dependencies with minimal lock-in.

How to Pitch It (Stakeholders)

For Executives: "This package lets us standardize how we handle critical data types (like IDs, names, and passwords) across our PHP services, reducing bugs and speeding up development. For example, instead of writing custom UUID validation or slug generators, we’ll use pre-built, secure components—saving time and ensuring consistency. It’s a low-risk investment (MIT license) that aligns with modern software design practices, and it’s easy to adopt incrementally. The long-term payoff is cleaner code, fewer edge-case errors, and easier maintenance."

For Engineers: *"This gives us a set of ready-to-use value objects (e.g., UuidV4, DateTimeRange, StrongPasswordField) that enforce type safety and validation at the object level. Key benefits:

• No more reinventing wheels: Pre-built classes for common patterns (slugs, enums, ranges).
• DDD-friendly: Aligns with domain modeling by treating data as immutable objects.
• Extensible: We can subclass or compose these objects (e.g., UserIdentifier extends UuidV4) to fit our needs.
• Security: Built-in checks for passwords, UUIDs, etc., reduce vulnerabilities.
• Future-proof: Part of the Apie ecosystem, so we can add composite objects later if needed.

Tradeoff: It’s a new dependency (0 stars, but MIT-licensed and actively maintained in the monorepo). Let’s prototype it in one service first to validate the ROI."*
