KurrentDB PHP Client 0.20.0

🛠️ Improvements

• Major Architecture Refactoring: Complete implementation of facade pattern with service segregation

  • EventStore is now a pure facade delegating to specialized services
  • StreamReader handles all stream reading operations
  • StreamWriter manages stream writing and deletion
  • StreamIteratorFactory creates stream iterators for navigation

• Dependency Injection: Full implementation of proper dependency injection

  • HttpErrorHandler is now a shared dependency across services
  • StreamFeedFactory and EntryFactory are injected rather than created internally
  • EventStoreFactory manages all service dependencies and lifecycle

• Factory Pattern: EventStoreFactory is now the recommended way to create EventStore instances

  $factory = new EventStoreFactory($uriFactory, $requestFactory, $httpClient);
  $eventStore = $factory->create();

• Code Quality: Improved adherence to SOLID principles

  • Interface segregation with focused service interfaces
  • Dependency inversion throughout the service layer
  • Better separation of concerns and testability

• Developer Experience: Enhanced documentation and tooling

  • Updated README.md with new architecture examples
  • Added dependency validation with make check-src-deps
  • CI pipeline now includes dependency checking

🔧 Breaking Changes

• EventStore Constructor: Now requires service dependencies instead of HTTP clients

  // Before
  $eventStore = new EventStore($uri, $httpClient);
  
  // After (recommended)
  $factory = new EventStoreFactory($uriFactory, $requestFactory, $httpClient);
  $eventStore = $factory->create();

• Service Constructors: StreamReader and StreamWriter now require additional dependencies

  • HttpErrorHandler must be injected
  • StreamFeedFactory must be injected into StreamReader

📦 Dependencies

• Added explicit PSR dependencies: psr/http-message, psr/http-client, psr/http-factory
• Updated to ensure all used interfaces are explicitly declared
