Example 07: Service Registration Pattern

Overview​

The service registration pattern implements a sophisticated dependency injection system that integrates with SYSPRO's plugin architecture while maintaining clean separation of concerns.

Implementation​

Registration Architecture​

The RegisterServiceProvider class orchestrates service registration:

  • MepDash plugin services
  • Application services
  • Singleton lifecycles
  • Configuration injection

Service Lifecycle Management​

Careful lifecycle management ensures:

  • Proper initialization order
  • Resource sharing
  • Memory efficiency
  • Clean disposal

Integration Points​

Services integrate with:

  • SYSPRO session management
  • Database contexts
  • Logging infrastructure
  • Configuration systems

Dependency Resolution​

Service Dependencies​

Complex dependency graphs:

  • Circular dependency prevention
  • Lazy initialization
  • Factory patterns
  • Service locator pattern

Configuration Injection​

Configuration management:

  • Environment-specific settings
  • Runtime configuration
  • Secret management
  • Feature flags

Testing Support​

The pattern enables:

  • Unit test isolation
  • Mock injection
  • Integration testing
  • Performance testing

Benefits​

This pattern provides:

  • Clean architecture
  • Testable code
  • Flexible configuration
  • Maintainable structure

Summary​

The service registration pattern provides a robust foundation for dependency management, enabling clean architecture and testable code while integrating seamlessly with SYSPRO's infrastructure.
