go-dependency-injection

What problem does it solve?

Go dependency injection guidelines to improve testability, modularity, and maintainable architectures in Go projects.

Core Features & Use Cases

• Define small, focused interfaces to decouple components and enable mock implementations.
• Use constructor-based wiring and patterns like functional options to assemble services cleanly.
• Leverage Uber Fx or Google Wire for scalable, type-safe dependency wiring and lifecycle management in real-world Go projects.
• Apply in service boundaries, clean architecture modules, and testable repositories to reduce coupling and improve testability.

Quick Start

Create a minimal Go module that wires a repository and a service using constructor-based DI with either Fx or Wire to demonstrate a startup.
