Products, Todo, and Auth REST API

This is a combined REST API for managing products and todo tasks, with JWT-based authentication and authorization. The API uses PostgreSQL for database management, Echo v4 as the web framework, and godotenv for environment variable management. It also includes image uploads for products, and static files are served using Nginx.

Features

• JWT Authentication: User registration and login with secure JWT tokens.
• Todo Management: Create, read, update, and delete todo items.
• Product Management: Full CRUD operations for products, including image uploads.
• PostgreSQL Integration: Uses PostgreSQL as the database.
• Nginx for Static Files: Nginx serves static files for products' images.

Tech Stack

• Golang: Backend API with Echo framework.
• PostgreSQL: Database for storing todos, products, and users.
• JWT: For secure authentication and authorization.
• Echo v4: Web framework used for routing.
• godotenv: For environment variable management.
• Nginx: For serving static files.
