LeetCode Clone with .NET 8.0

Development Status: This project is in active development and is not production-ready. Breaking changes are expected until the first stable release.

This is a LeetCode inspired coding challenge platform built with .NET 8.0.
It allows users to solve coding problems and have their code executed securely inside Docker containers.

Features

User Management

• Authentication: ASP.NET Core Identity with JWT token-based authentication
• Profile Management: User registration, login, and profile customization

Data Layer

• Database: PostgreSQL for reliable data persistence
• Configuration: Flexible database connection setup

Code Execution

• Secure Sandbox: Docker-based isolation for safe code compilation and execution
• Multi-Language Support: Python and C/C++ challenges
• Security: Prevents malicious code from affecting the host system

Technology Stack

• Backend: .NET 8.0, ASP.NET Core
• Authentication: ASP.NET Core Identity, JWT
• Database: PostgreSQL
• Message Broker: RabbitMQ
• Containerization: Docker & Docker Compose
• Supported Languages: Python, C/C++

Architecture

Getting Started

Prerequisites

Before you begin, ensure you have the following installed

• Docker and Docker Compose
• .NET 8 SDK (optional - only needed for local development outside Docker)

Setup Instructions

Clone the repository

  git clone https://github.com/KakhaberiKarenashvili/LeetCode-Clone-with-.NET-8.0.git
  cd LeetCode-Clone-with-.NET-8.0

Start the application

  docker-compose up --build

Access the application

• Open your browser and navigate to http://localhost:5001

Configuration (Optional)

The application uses PostgreSQL and RabbitMQ services that are automatically configured via Docker Compose. If you prefer to use external services, update the configuration in appsettings.json:

Database Configuration:

{
  "ConnectionStrings": {
    "DBConnection": "Host=your-host;Port=5432;Database=your-database;Username=your-username;Password=your-password;"
  }
}

Message Broker Configuration:

{
  "MessageBroker": {
    "Host": "amqp://your-rabbitmq-host:5672",
    "UserName": "your-username",
    "Password": "your-password"
  }
}

Why Docker?

This platform must run inside Docker because the code execution service runs in a Linux-based container with:

• Security: Isolated execution environment prevents malicious code from affecting the host system
• Consistency: Ensures consistent runtime environment across different development machines
• Language Support: Pre-configured Linux container with Python and GCC compilers

Development Notes

• The project must run inside Docker containers for security reasons
• Code execution happens in isolated Linux containers with pre-installed compilers
• Frequent changes are expected during the development phase
• Database migrations are handled automatically on startup
