SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps to organize and implement services that encapsulate business logic, improving maintainability and scalability of applications.

Core Features & Use Cases

  • Service Encapsulation: Encapsulate business logic in services for better separation of concerns.
  • Dependency Injection: Utilize constructor-based dependency injection for services.
  • Single Responsibility: Ensure each service handles a single domain concern.
  • Repository Delegation: Delegate data access to repositories, maintaining separation of concerns.
  • Context-Aware Services: Design services to be context-aware with context.Context support.
  • Interface-Driven: Use interfaces for service implementations to promote composable and auditable code.
  • Single File Exports: Export all service interfaces from a single file for better organization.
  • Use Case: For a shopping cart application, encapsulate the business logic for adding items to the cart, processing payments, and generating order summaries in separate services.

Quick Start

Implement a new service for managing user profiles by following the guidelines outlined in the SKILL.md.

FAQPage Schema
When should I design context-aware services in Go?

You need knowledge of Go and dependency injection patterns to use this service design approach, which targets developers building robust, maintainable applications with clear interfaces and separation of concerns.

What is the best way to organize service interfaces in Go?

The best way to organize service interfaces in Go is exporting all service interfaces from a single file, promoting composable, auditable code while utilizing interface-driven implementations for clear separation of concerns.

How do I encapsulate business logic for a Go application?

Encapsulate business logic in Go by grouping domain-specific operations into distinct services, ensuring each service handles a single domain concern and delegates data access to repositories for scalable architecture.

Why use constructor-based dependency injection for service design?

Constructor-based dependency injection ensures each service receives its dependencies explicitly, maintaining single responsibility principles and making your service design composable, auditable, and easier to test.
