Dependency Injection in Go: A Primer

Dependency Injection (DI) is a software design pattern that allows for decoupling components and layers in a system. By providing dependencies from the outside rather than hard-coding them within a component, we achieve better modularity, testability, and flexibility. Go, despite its simplicity, can be enhanced with DI patterns to build scalable and maintainable applications. In this blog post, we'll explore what Dependency Injection is, why it's useful, and how to implement it in Go with code examples.
