Project Description:

The Real-Time Collaborative Code Editor is a web-based platform that allows multiple users to write, edit, and debug code simultaneously in real time. This project mimics platforms like Google Docs (but for code) and is useful for pair programming, coding interviews, educational purposes, and remote development teams.

It supports syntax highlighting, language selection, auto-save, and real-time syncing using WebSockets or similar technologies. This can also include a chat feature, code execution, and version history tracking.

Key Features:

1. Multi-User Collaboration:

   • Real-time synchronization using WebSockets (e.g., Socket.IO in Node.js).

   • All users see live code changes as they happen.

2. Code Editor Functionality:

   • Syntax highlighting for multiple languages (HTML, JS, Python, C++, etc.).

   • Line numbering, auto-indentation, theme switcher (light/dark).

   • Support for keyboard shortcuts and multi-cursor editing.

3. Authentication & Session Management:

   • Users can create accounts or join anonymously.

   • Option to create a new code session or join an existing one via invite link.

4. Live Chat Panel:

   • In-built chat to communicate with other collaborators during sessions.

5. Code Execution:

   • Integrate backend services (e.g., Judge0 API or custom sandbox) to run code in supported languages.

6. Code History & Undo:

   • Maintain history of changes with undo/redo support.

   • Option to download or revert to earlier versions.

7. Role-based Access:

   • Owner (edit + manage), Editors (edit), Viewers (read-only).

8. Project Room Management:

   • Multiple rooms with unique IDs.

   • Password protection or invite-only access to rooms.

Tech Stack Suggestions:

• Frontend:

  • HTML, CSS, Bootstrap, JavaScript

  • Code editor library: Monaco Editor (used in VS Code) or Ace Editor

• Backend Options:

  • Node.js + Express with Socket.IO for real-time communication

  • Java (Spring Boot) or PHP (with Ratchet for WebSocket) for collaboration backend

• Database:

  • MongoDB or MySQL for storing users, code snippets, session data

• Code Execution API (Optional):

  • Judge0, JDoodle API, or custom Docker-based sandbox
