factory-function-composition

What problem does it solve?

This pattern helps developers enforce clear separation of concerns by injecting dependencies via factory functions, reducing hidden dependencies and improving testability.

Core Features & Use Cases

• Enables creation of services with injected clients and resources
• Supports multi-dependency factories and explicit option layering
• Improves testability by enabling mocks and isolation
• Use Case: When wiring together a client, a service, and its method options in a stable, predictable way

Quick Start

Create a service by wiring dependencies with a factory and call a method to exercise the resulting service.
