To enforce SOLID principles in Go, structure projects using modular architecture with strict file size limits and interface segregation. This prevents tight coupling by mandating small, focused interfaces in dedicated ports directories and ensuring adherence to layered responsibilities across handlers, services, and repositories.

The best way to structure Go code for maintainability is using modular architecture with an internal/modules/[feature]/ directory layout. This enforces clear separation of concerns, keeps files under 100 lines for readability, and mandates single responsibility across handlers, services, and repositories.

Yes, you can refactor existing Go applications to adopt clean code by enforcing interface segregation. This involves breaking down large interfaces into small, focused ones with 1-3 methods, placing them in dedicated ports directories, and reorganizing code into modular structures with layered responsibilities.

Enforcing clean code in Go benefits from strict file size limits, specifically keeping files under 100 lines. This promotes readability and single responsibility, preventing god objects and ensuring the codebase remains modular, maintainable, and testable.

Go architecture develops god objects when files lack strict size limits and layered responsibilities. Fix this by refactoring to a modular architecture that enforces files under 100 lines, uses dedicated ports directories for interface segregation, and separates concerns across handlers, services, and repositories.

Applying strict SOLID architecture to Go 1.23+ projects requires adherence to rigid constraints: files must stay under 100 lines and interfaces must contain 1-3 methods in ports directories. This may require significant refactoring effort for existing codebases with large files or coupled components.
