nakabonne/cleanarchitecture-sample

This system is a sample Go application designed to demonstrate Clean Architecture principles. It provides a structured codebase with a Gin-based HTTP server and a MySQL-backed user repository using GORM. The primary functionality allows users to manage user data through health check and creation endpoints, enforcing separation of concerns across domain and use-case layers.

The application is now available as a Go module, introducing a complete Clean Architecture structure. This includes a Gin-based HTTP server exposing endpoints for health checks and user creation, a MySQL-backed user repository using GORM, and domain/use-case layers that enforce separation of concerns. Users can now run the sample service to manage user data with a structured, modular codebase.

src · high confidence

The project now uses Go modules for dependency management, introduced by adding go.mod and go.sum files. This establishes the module path as github.com/nakabonne/cleanarchitecture-sample, sets the Go version to 1.13, and pins direct dependencies including gin v1.4.0, gorm v1.9.10, and pkg/errors v0.8.1.
