Vendor Bundle Laravel Package

Product Decisions This Supports

• Domain-Driven Design (DDD) Adoption: Enables clean separation of domain logic (entities, repositories) from application services, aligning with DDD principles for maintainable, scalable architecture.
• Modularity & Reusability: Facilitates bundling domain logic into reusable packages, reducing duplication and easing vendor/service integration (e.g., third-party APIs, SaaS tools).
• Build vs. Buy: Justifies building a custom domain layer over buying monolithic solutions when domain complexity requires tailored logic (e.g., e-commerce, logistics, or niche workflows).
• Roadmap for Microservices: Paves the way for future decomposition into microservices by isolating domain boundaries early.
• Vendor Abstraction: Simplifies swapping dependencies (e.g., payment gateways, shipping providers) by encapsulating vendor-specific logic in the bundle.

When to Consider This Package

• Adopt if:
  • Your Laravel app has growing domain complexity (e.g., >50% of logic tied to external vendors/APIs).
  • You need clear separation between domain models (entities/repositories) and application layers.
  • Your team prioritizes long-term maintainability over quick hacks (e.g., monolithic service classes).
  • You’re integrating multiple vendors (e.g., Shopify + PayPal + FedEx) and want to avoid spaghetti code.
• Look elsewhere if:
  • Your project is small-scale or prototype-only (overhead of DDD may not justify benefits).
  • You lack developer buy-in for DDD principles (requires discipline in design).
  • Existing Laravel packages (e.g., Laravel Modules, Glide) already meet your modularity needs.
  • Your domain logic is trivial (e.g., CRUD apps with no external dependencies).

How to Pitch It (Stakeholders)

For Executives: "This package lets us future-proof our vendor integrations by isolating domain logic into reusable bundles. Think of it like a ‘plug-and-play’ system: Swapping a payment provider or shipping service becomes as easy as swapping a lightbulb. It reduces technical debt, speeds up feature delivery for new vendors, and aligns with our long-term architecture goals. Early adoption here will save us months of refactoring later."

For Engineering: *"Carguru’s VendorBundle gives us a structured way to encapsulate vendor-specific logic (e.g., Shopify product syncs, Stripe payments) into domain entities and repositories. This means:

• Cleaner code: No more ‘god classes’ handling 10 vendors.
• Easier testing: Mock repositories instead of API calls.
• Scalability: Add new vendors without touching core app logic.
• Team alignment: Forces us to think in DDD, which pays off as we grow. Downside: A slight upfront cost to refactor existing vendor logic into the bundle, but it’s a one-time investment for long-term gains."*

For Developers: *"This is like Laravel’s Eloquent, but for vendor APIs. Instead of scattering Shopify::syncProducts() across controllers, we’ll define a ProductRepository interface and implement it for each vendor. Benefits:

• Type safety: Autocomplete for domain methods (e.g., repository->fetchBySku()).
• No more ‘magic strings’: Vendor API endpoints/config live in one place.
• Collaboration: Other teams can extend the bundle without touching your code. Tradeoff: You’ll need to rewrite a few vendor classes to fit the pattern, but it’s worth it for large projects."*
