DevSync - Encrypted Code & Text Sharing

Overview

DevSync is a secure and encrypted code/text-sharing platform designed for developers and teams. Built with a layered architecture, it ensures privacy, real-time access, and efficient handling of data.

🏗 Architecture Overview

The system is designed using a modular approach with different layers handling specific responsibilities.

1️⃣ User Interaction Layer

• Next.js UI – Modern, responsive frontend for user interaction.
• Form Validation – Ensures proper input before submission.
• API Call Handling – Manages communication with the backend.

2️⃣ API Gateway

• Middleware – Processes incoming requests.
• Request Processing – Handles incoming API calls.
• Authentication – Secure access control.
• Rate Limiting – Prevents abuse and excessive usage.

3️⃣ Business Logic Layer

• Data Validation – Ensures data integrity before storing.
• Storage Logic – Manages how data is written to the database.
• Retrieval Logic – Handles fetching of stored data.
• Optional Encryption – Encrypts stored snippets for enhanced security.

4️⃣ Database Layer

• PostgreSQL – Stores encrypted text/code snippets.
• Schema:
  • Key – Unique identifier for each snippet.
  • Text – Encrypted or raw text data.
  • Created_at – Timestamp of snippet creation.
  • Expiration_time – Auto-deletion schedule for snippets.

5️⃣ Security Layer

• Input Sanitization – Prevents SQL injection and XSS attacks.
• Logging & Monitoring – Tracks system activity for security and debugging.

6️⃣ Background Jobs

• Expiry System – Removes expired snippets automatically.
• Alerts & Logs – Monitors system health and security events.

🚀 Features

✅ End-to-End Encryption for private sharing
✅ Self-destructing Snippets with expiration controls
✅ Real-time API for developers
✅ Secure & Scalable PostgreSQL Backend

📜 How It Works

1. User submits code/snippet via the Next.js UI.
2. The API Gateway authenticates and processes the request.
3. The Business Logic Layer validates and optionally encrypts data.
4. Snippet is stored securely in PostgreSQL with an expiration time.
5. Expired snippets are deleted automatically via background jobs.

📌 Setup

To deploy DevSync, follow these steps:

git clone https://github.com/Suhaib3100/DevSync.git
cd DevSync
docker-compose up -d
