Golang Backend Development

To structure a scalable Golang backend, adopt a layered architecture separating handler, service, and repository responsibilities. This enforces consistent coding practices, improves maintainability, and aligns new projects with existing repositories.

To implement dependency injection in a Go backend, initialize dependencies via constructors and strictly enforce their flow between layers. This ensures components remain decoupled, which simplifies testing and maintains clear architectural boundaries.

Using raw SQL in Golang backend development provides direct control over database queries within the repository layer. This practice aligns with strict layered architecture standards, ensuring predictable performance and avoiding ORM abstraction overhead.

Organize testing patterns for a layered Go backend by isolating tests across the handler, service, and repository layers. Strict dependency injection allows mocking dependencies effectively, ensuring thorough test coverage and reliable validation of business logic.

This Golang backend standard can work for small services, but it is designed to satisfy typical backend architectures at scale. Implementing the handler, service, and repository pattern ensures future scalability and easier onboarding regardless of initial service size.
