Go REST API (Gin + GORM + PostgreSQL + Viper + Zap)

A clean and scalable Go REST API starter built using:

• Gin – HTTP router & middleware
• GORM – ORM for PostgreSQL
• Viper – Configuration & environment management
• Zap – Structured logging (Uber)
• Clean Architecture with cmd/, internal/, pkg/

This repository provides a production-ready base for building APIs with proper structure, configuration management, logging, services, and repository layer.
