Dependency Injection in Go: Is Manual Wiring the Best Approach?

Dependency Injection in Go: Is There a Better Way?

In Go, wiring dependencies manually in the main function is a common practice. However, some developers may find this approach repetitive or overly verbose. This begs the question: is there a more efficient or elegant way to handle dependency injection in Go?

Overcoming the Manual Wiring Approach

While the manual wiring approach is straightforward, it can become cumbersome in larger projects with numerous dependencies. This is because every time a dependency is introduced, it must be explicitly passed to the consumer function.

The Best Practice: Embrace Go Simplicity

Contrary to popular belief, the best practice in Go is not to employ a dependency injection library or framework. Go is renowned for its simplicity and clarity. Adding an additional layer of abstraction through a DI library may obscure the flow of dependencies and make code more difficult to understand.

Conclusion

While dependency injection libraries may provide convenience in other programming languages, they are generally unnecessary in Go. By embracing the simplicity of the language, developers can maintain clear and concise code without sacrificing maintainability or extensibility.
