This project structure is designed for Golang projects and is based on the hexagonal architecture, with some modifications😵.

This directory serves as the entry point for the application, containing the main.go file. Keep the code in this directory minimal.

This directory contains the functional code for the application, including routing and database interactions.

This directory contains the configuration file for the database used in the project. In this example, the database used is PostgreSQL.

This directory contains two files: repository.go and service.go. These files define the functions of the application, with repository.go responsible for querying the database (Data Access Layer) and service.go containing the business logic.

This directory contains the ORM (such as gorm) used to query the database on function calls from the service layer.

This directory contains functions called by the repository layer and contains the business logic of the application. It is framework agnostic.

This directory contains the application's routes and is not framework agnostic. Functions in this directory can only call the service layer.

This directory contains the database models with gorm and json extensions.

This directory contains the middleware functions used inside the handler directory

This directory contains any repeating code, such as code for generating IDs or verifying tokens.

This project structure is not suitable for small projects and may become unwieldy for large projects.
