Overview

The Collaborative Online Judge System represents a sophisticated full-stack project designed to enhance the coding and problem-solving experience for users. Built with a modern Angular-based front end and a NodeJS restful API, it leverages a Docker-based code execution engine for seamless performance. This system is not only built for individual users to tackle problems but also facilitates real-time collaboration among multiple users, making it ideal for educational environments and programming contests.

The architecture of this system provides a robust solution to managing user-generated content and interactions. With support for CRUD (Create, Read, Update, Delete) operations for problems, the project ensures that both administrators and users can effectively contribute to and engage with a wide array of coding challenges. This setup serves as an excellent platform for aspiring developers to hone their skills while nurturing community collaboration.

Features

  • Real-Time Collaboration: Users can collaborate on problems simultaneously, enhancing learning and problem-solving effectiveness.
  • Robust API Integration: A NodeJS based restful API enables seamless communication between the front end and the database, ensuring swift data handling.
  • User Management System: Designed to effectively manage user roles and permissions, ensuring a secure environment for all participants.
  • Dynamic Problem Management: Administrators can easily create, read, update, and delete coding problems, keeping the content fresh and relevant.
  • High Scalability: Utilizing load balancers and Docker, the system can handle a high volume of users and code submissions, ideal for peak performance scenarios.
  • WebSocket Communication: Facilitates real-time data transmission between users and the server, essential for an interactive coding environment.
  • Code Execution Engine: Integrated Docker-based engine for executing submitted code efficiently and securely, providing immediate feedback to users.
  • Data Handling Efficiency: The system is optimized for high-frequency operations, ensuring that data is transmitted and stored with minimal latency.
