❗ Problem Statement

Aspiring developers often lack access to a beginner-friendly and structured platform that supports real-time practice, progress tracking, and interview-level coding problems — all in one place. Existing platforms are either paywalled, cluttered, or lack collaboration.

---

🎯 Objectives

• ✅ Structured coding problem sets categorized by difficulty.
• ✅ Real-time code collaboration using WebSockets.
• ✅ Secure authentication & user sessions.
• ✅ Admin-level problem management and uploads.
• ✅ Intuitive UI for smooth coding workflows.
• ✅ Beginner-focused, free-to-use experience.

🛠️ Tech Stack

Frontend	Backend	Realtime	Storage / Database
React.js + TypeScript	Node.js + Express.js	Socket.IO	MongoDB (NoSQL)
Vite + CSS	Multer (file uploads)	WebSocket Protocol	Local Disk for files
CodeMirror / Monaco	CORS Middleware	Room Events	Memory & DB Storage

🧠 System Architecture

• Frontend: Built with React + Vite + TypeScript. Handles the UI, problem display, authentication, and WebSocket sync.
• Backend: Node.js + Express with REST APIs for problems, users, and submissions. Handles Multer uploads and room sync.
• Database: MongoDB to store user data, problem sets, and submissions.
• Real-Time Engine: Socket.IO enables collaborative editing via WebSocket connections.

🧩 Modules

1. User Interface

• Responsive interface for problems, dashboard, login/signup.
• Dynamic rendering of problems and editors.

2. Authentication

• Secure login/signup.
• JWT or session-based auth.
• CORS-protected routes.

3. Problem Management

• Admin APIs for creating/editing problems.
• Metadata includes title, description, sample I/O, difficulty.

4. Solution & Evaluation

• Submit solutions with metadata.
• Track submission history and status.

5. Collaboration

• Live typing and sync across multiple users in a room.
• WebSocket-driven updates.

6. File Upload

• Accepts only .js, .py, .cpp, .txt, etc.
• Validates max 20MB size, rejects folders/ZIPs.

7. Progress Tracking

• Monitor attempted/solved problems.
• Display analytics, streaks, and category stats.
