Go REST API Server

From my time as a Hashicorp intern where the I was mentored in go by the talented Johan Brandhorst-Satzkorn

This began using the standard library then as an evolution to teach myself popular libraries, i integrated Gorilla Mux

A production-grade RESTful API server built with Go, implementing modern backend development practices and features. This project represents my first venture into building a production-ready Go server, incorporating essential features for robust API development.

🌟 Key Features

• MVC Architecture: Clean separation of concerns with Models, Controllers, and a structured data store
• PostgreSQL Integration: Robust database integration using a PostgreSQL store
• RESTful Endpoints: Well-structured API endpoints for:
  • User management (CRUD operations)
  • Todo management
• Authentication: User authentication system with login functionality
• Error Handling: Centralized error handling with proper HTTP status codes
• Middleware Support: Using Gorilla Mux for routing and middleware
• Clean Project Structure:

  ├── controllers/    # Request handlers and business logic
  ├── models/        # Data models
  ├── server/        # Server configuration and setup
  ├── store/         # Database interactions
  ├── todos/         # Todo-related functionality
  ├── users/         # User management functionality
  └── utils/         # Shared utilities and helpers
  

🛠️ Technologies Used

• Go (Golang)
• Gorilla Mux (Router)
• PostgreSQL
• JWT for authentication

🚀 Getting Started

1. Ensure you have Go installed and PostgreSQL running
2. Clone the repository
3. Set up your PostgreSQL database
4. Update the database connection string in main.go
5. Run the server:

   go run main.go

   The server will start on localhost:5000

📡 API Endpoints

Users

• POST /login - User authentication
• GET /users - Get all users
• GET /users/{id} - Get user by ID
• POST /users - Create new user
• DELETE /users/{id} - Delete user

Todos

• GET /todos - Get all todos
• GET /todos/{id} - Get todo by ID

💡 Learning Highlights

This project served as an excellent learning experience in:

• Implementing clean architecture in Go
• Setting up proper error handling and response structures
• Working with PostgreSQL in a Go environment
• Building secure authentication systems
• Structuring a production-ready REST API

🔒 Security Features

• Secure password handling
• JWT-based authentication
• Proper error handling to prevent information leakage
