SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a clear and maintainable way to manage the dependencies of the project, ensuring that all necessary components are initialized correctly and resources are properly released.

Core Features & Use Cases

  • Eager Initialization: All dependencies are created at startup for fail-fast behavior.
  • Explicit Wiring: No reflection or magic, making the dependency graph transparent.
  • Single Container: A central Dependencies struct holds all application dependencies.
  • Resource Management: Ensures proper cleanup of resources via a Close() method.
  • Use Case: When adding a new service, this Skill guides you through integrating it into the existing dependency container, ensuring it's available and managed correctly throughout the application's lifecycle.

Quick Start

Use the dependency-injection skill to understand how to add a new dependency to the project's dependency container.

FAQPage Schema
How do I manage project dependencies in Golang without using reflection?▼

To add a new service, integrate it into the existing dependency container. This ensures the new dependency is properly initialized, managed correctly via getter methods, and cleaned up through the container's Close() method.

How do I add a new service to an existing dependency container?▼

To add a new service, integrate it into the existing dependency container. This ensures the new dependency is properly initialized, managed correctly via getter methods, and cleaned up through the container's Close() method.

What's the best way to ensure proper resource cleanup for initialized dependencies?▼

Yes, the dependency injection pattern supports testing by allowing the creation of real dependency instances with test configurations. This enables you to inject mock or specific test data into the explicit wiring.

Why use eager initialization for a dependency injection container?▼

Use eager initialization to create all dependencies at startup for fail-fast behavior. This immediately exposes configuration or wiring errors, ensuring all components are ready before the application serves requests.

Can I use dependency injection to support testing in my project?▼

Yes, the dependency injection pattern supports testing by allowing the creation of real dependency instances with test configurations. This enables you to inject mock or specific test data into the explicit wiring.
