How should a project’s file structure be organized in Golang?

In Go, it is common to organize the project structure to be simple and understandable, with clear separation of responsibilities. General recommendations:

• cmd/ — folder with entry points (executable files), for example, cmd/app/main.go.
• internal/ — private packages that should not be used outside the project.
• pkg/ — public libraries that can be used by other projects.
• api/ — API descriptions, protobuf, swagger, etc.
• configs/ — configuration files.
• scripts/ — scripts for build, deployment, migrations.
• test/ — additional test data and utilities.

Example:

myproject/
├── cmd/
│   └── myapp/
│       └── main.go
├── internal/
│   ├── service/
│   └── repository/
├── pkg/
│   └── utils/
├── api/
├── configs/
├── scripts/
└── test/

This approach helps maintain code cleanliness and facilitates project scaling.
