SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Dependency injection in Go helps build testable, loosely coupled code by decoupling constructors from concrete implementations, reducing global state, and enabling flexible wiring of services.

Core Features & Use Cases

Understands when to use manual constructor injection vs. DI libraries (wire, dig/fx, samber/do)
Provides guidance on interface design at the consumer boundary and lifecycle considerations
Includes quick-start patterns for common project sizes (small apps vs. large microservices)

Quick Start

Describe a practical DI plan for a Go service, including constructor injection examples and library options.

FAQPage Schema

How do I implement dependency injection in Go for scalable services?▼

Dependency injection in Go is implemented via manual constructor injection or libraries like wire and fx, decoupling constructors from concrete implementations to build testable and loosely coupled services.

What is the best way to choose between wire, fx, and samber/do for Go dependency injection?▼

Choose between wire, fx, and samber/do by evaluating your project size and lifecycle needs; wire offers compile-time safety, while fx and samber/do provide runtime injection and lifecycle management features.

Do I need a dependency injection library for a small Go application?▼

You do not need a dependency injection library for a small Go application; manual constructor injection is often sufficient, reserving libraries like wire or fx for larger microservices requiring complex wiring.

Why should I define interfaces at the consumer boundary when using dependency injection in Go?▼

Defining interfaces at the consumer boundary in Go dependency injection ensures loose coupling and testability, allowing you to mock dependencies easily without exposing unnecessary implementation details.

When should I avoid global state in Go dependency injection?▼

You should avoid global state in Go dependency injection entirely to maintain testable code, as global variables hide dependencies and make orchestration with libraries like dig or fx unpredictable.
