Contracts Laravel Package

Technical Evaluation

Architecture Fit

• Strong alignment with Laravel’s ecosystem: Contracts are tailored for Laravel 11/12, Symfony 6/7, and PHP 8.3+, ensuring seamless integration with modern Laravel applications.
• Clean Architecture & Dependency Inversion: Enables strict separation of concerns by defining interfaces for core systems (e.g., Cache\Store, Queue\ShouldQueue), making implementations swappable and testable.
• Modularity & Reusability: Ideal for modular monoliths or microservices where shared contracts reduce coupling between components.
• Framework-Agnostic Abstractions: While Laravel-specific, the contracts (e.g., Dtoable, Http\Builder) are generic enough to work across PHP projects using similar patterns.

Integration Feasibility

• Low-Coupling Design: Contracts are pure interfaces with no runtime dependencies beyond PHP, making them non-intrusive to existing codebases.
• Composer-First Adoption: Simple installation (composer require dragon-code/contracts) with zero configuration required.
• Backward Compatibility: MIT-licensed with no breaking changes in major versions (e.g., Laravel 11/12 support added incrementally).
• Symfony Dependency: Uses symfony/http-kernel (v6/7/8), which is already a Laravel dependency, reducing friction.

Technical Risk

Key Questions for TPM

1. Architecture Goals:

   • Is the team adopting clean architecture, DDD, or hexagonal design? If not, the value of contracts may be limited.
   • Are we building reusable internal packages or modular services? If yes, contracts accelerate development.

2. Laravel Version Strategy:

   • What’s the target Laravel version (11/12)? Ensure alignment with the package’s support matrix.
   • Is the team using Symfony 6/7/8 elsewhere? This package’s Symfony dependency may introduce consistency.

3. Adoption Scope:

   • Should we mandate contracts for all new components or adopt opt-in?
   • How will we enforce contract usage (e.g., static analysis, CI checks)?

4. Ecosystem Integration:

   • Are we using DragonCode’s other packages (e.g., helpers)? If yes, contracts like Dtoable are required.
   • Will this enable shared contracts across microservices or internal libraries?

5. Testing & Mocking:

   • How will contracts improve testability? (e.g., mocking Cache\Store instead of concrete implementations.)
   • Should we refactor existing tests to leverage these interfaces?

6. Performance Impact:

   • Are there performance concerns with interface-based dispatch? (None; contracts are compile-time only.)

7. Long-Term Maintenance:

   • Who will monitor updates (e.g., Laravel 13 compatibility)?
   • Should we fork the package if DragonCode abandons it?

Integration Approach

Stack Fit

Migration Path

1. Assessment Phase:

   • Audit existing custom interfaces (e.g., for caching, queues, DTOs).
   • Identify high-value candidates for replacement (e.g., ShouldQueue, Dtoable).

2. Pilot Integration:

   • Start with one module/service (e.g., a new feature or internal package).
   • Replace 2-3 custom interfaces with DragonCode’s contracts (e.g., Cache\Store instead of App\Contracts\CacheInterface).

3. Incremental Adoption:

   • Phase 1: Replace DTO-related interfaces (e.g., Dtoable for serialization).
   • Phase 2: Standardize queue/job contracts (ShouldQueue, ShouldBeUnique).
   • Phase 3: Adopt HTTP/caching contracts (Http\Builder, Cache\Ttl).

4. Enforcement:

   • Add PHPStan/PSR-12 checks to enforce contract usage in new classes.
   • Update CI/CD pipelines to fail on missing contract implementations.

5. Deprecation:

   • Gradually deprecate custom interfaces in favor of DragonCode’s.
   • Use abstract base classes to bridge old and new contracts during transition.

Compatibility

Sequencing

1. Pre-requisites:

   • Upgrade to Laravel 11/12 and PHP 8.3+.
   • Ensure Symfony 6/7/8 compatibility in the stack.

2. Critical Path:

   • Step 1: Install dragon-code/contracts in the root project and key packages.
   • Step 2: Replace DTO interfaces first (lowest risk, high reward).
   • Step 3: Standardize queue/job contracts (ShouldQueue, ShouldBeUnique).
   • Step 4: Adopt caching/HTTP contracts (Cache\Store, Http\Builder).

3. Parallel Work:

   • Refactor tests to use contract interfaces for mocking.
   • Update documentation to reflect new contract usage.

4. Post-Integration:

   • Monitor performance impact (none expected; contracts are compile-time).
   • Evaluate developer feedback on usability (e.g., IDE autocompletion, clarity).
