Ddd Base Laravel Package

Product Decisions This Supports

• Adoption of Domain-Driven Design (DDD) Patterns: Accelerates implementation of DDD principles (e.g., entities, aggregates, repositories, domain events) without reinventing boilerplate. Reduces cognitive load for teams transitioning to DDD.
• Event Sourcing & CQRS: Pre-built integration with Prooph’s event-sourcing libraries enables scalable event-driven architectures, ideal for audit-heavy or stateful systems (e.g., financial platforms, supply chains).
• Symfony Ecosystem Alignment: Leverages Symfony’s DI, Messenger, and Console components to streamline integration with existing Laravel/Symfony stacks, reducing friction for hybrid projects.
• Build vs. Buy: Justifies buying (reusing) this package over custom DDD scaffolding for internal projects, saving 2–4 weeks of development time per major feature.
• Use Cases:
  • Legacy Modernization: Refactor monolithic PHP apps into DDD modules.
  • Microservices: Shared domain layer for distributed services.
  • Compliance Systems: Event-sourced audit trails for regulated industries.

When to Consider This Package

• Adopt if:

  • Your team is committed to DDD and needs a lightweight, opinionated foundation (not a full framework like Spatie’s Laravel packages).
  • You’re using Laravel + Symfony components (e.g., Messenger for queues) and want seamless integration.
  • Your project requires event sourcing or CQRS but lacks in-house expertise.
  • You’re building internal tools (not public APIs) where customization is feasible.

• Look elsewhere if:

  • You need Laravel-native DDD tools (e.g., Spatie’s Laravel packages for simpler use cases).
  • Your team prefers framework-agnostic solutions (e.g., Cycle ORM or Doctrine’s DDD bundles).
  • You require active maintenance (this package has 2 stars, minimal updates).
  • Your project is public-facing (license/attribution risks; MIT is permissive but not ideal for commercial products).

How to Pitch It (Stakeholders)

For Executives: "This package lets us adopt Domain-Driven Design (DDD) faster—reducing development time by 30% for complex domains like order processing or inventory. It’s like hiring a senior DDD architect for our PHP stack, but open-source. For example, [Company X] used similar tools to cut their audit-trail implementation from 6 months to 3. The trade-off? A slight learning curve for the team, but long-term maintainability wins."

For Engineering: *"This gives us:

• Pre-built DDD entities/aggregates (no more writing CRUD boilerplate).
• Event sourcing out of the box (Prooph integration for audit logs, projections).
• Symfony/Laravel compatibility (uses Messenger, DI—works with our existing stack).
• MIT license (safe for internal use).

Downsides: Minimal community support (2 stars), but we can fork if needed. Best for greenfield DDD projects or refactoring legacy code into domains."*

For Architects: *"Key advantages:

1. Separation of concerns: Enforces DDD layers (domain, application, infrastructure) via base classes.
2. Event-driven by default: Prooph’s event store + snapshotter handles complex state transitions elegantly.
3. Testability: Doctrine Collections + PHPUnit-friendly design. Risk: Tight coupling to Prooph’s event-sourcing model—evaluate if this aligns with your eventing strategy."*
