Overview

QR Code Generator is a REST API that allows authenticated users to generate and manage QR codes. Built as a personal project to explore Go's ecosystem for building secure and well-documented APIs.

Features

• QR code generation from any text input, stored as image data in the database
• User authentication with registration, login, and JWT-based route protection
• Password hashing with bcrypt for secure credential storage
• Interactive Swagger docs for exploring and testing all endpoints
• Hot-reload development with Air for a fast feedback loop

API Endpoints

Method	Route	Description
POST	/api/auth/register	Create a new user account
POST	/api/auth/login	Authenticate and receive a JWT token
POST	/api/qrcode/generate	Generate a QR code (requires auth)

Tech Stack

The API is built with Go using Gin as the HTTP framework and GORM for database interaction with PostgreSQL. Authentication is handled through JWT tokens with bcrypt password hashing. The codebase follows a clean layered architecture with separate packages for controllers, services, repositories, models, and middlewares.
