DevNexus unifies the fragmented workflow of modern software engineers. It combines real-time collaborative coding, AI-powered assistance, Kanban-style task tracking, and documentation management into a single, cohesive ecosystem.
Unlike traditional applications that use slow database Regex queries (O(N) scanning), DevNexus leverages MongoDB Atlas Search.
- Architecture: Utilizes Apache Lucene Inverted Indexes to map content directly to documents.
- Performance: Achieves <10ms latency on searches across thousands of documents and code snippets (approx. 100x faster than standard queries).
- Capabilities: Enables Fuzzy Matching (typo tolerance), relevance scoring, and autocomplete functionality across the entire workspace.

-
Live Coding Rooms: Create instant rooms where multiple users can join via Room ID.
-
Socket.io Synchronization: See active users, typing indicators, and code changes in real-time. For data efficiency, we utilized MongoDB TTL indexes (24-hour expiry) for activity logs.
-
Integrated Compiler & Neural AI Engine: Powered by Google Gemini, offering instant "Explain Code" and "Refactor" capabilities with Direct Save to Code Vault. Supports execution in 7+ languages (C++, Java, Python, JS, etc.).
-
Documentation Hub: A dedicated space for project research and documentation with "Pin & Organize" functionality to keep critical notes at the top.
-
Advanced Editor: Built on TipTap, supporting bold, italics, code blocks, lists, and links.
- JWT Authentication: Stateless session management with secure HTTP headers.
- Reliable Recovery: Production-grade password reset flow using Brevo (SMTP) for high deliverability.
- Encryption: Sensitive data hashed using
bcryptjs.
- Syntax Highlighting: Store reusable algorithms with automatic language detection using react-syntax-highlighter.
- Direct Save: Push working code from the DevSpace compiler directly to your Vault.
- Smart Search: Instantly filter snippets by tags (e.g.,
#dp,#recursion) or title.
* **Resizable button**: to improve developer Experience
- Kanban Board: A drag-and-drop interface for managing engineering tasks.
- Visual States: Distinct visual indicators for Todo, In-Progress, and Completed items.
- Live Stats Aggregation: Automatically pulls and visualizes data from GitHub and LeetCode APIs.
- Smart Portfolio: Generates a public, shareable link (e.g.,
/u/username) that serves as a live resume. - Auto-Asset Generation: Uses OpenGraph to generate project cover images automatically.
DevNexus leverages a suite of powerful APIs to deliver a seamless experience:
- Socket.io: Enables bidirectional, real-time communication for the coding environment (DevSpace).
- Google Gemini API: Powers the Neural Engine for explaining code logic and refactoring suggestions.
- JDoodle / Compiler API: Provides the backend infrastructure for compiling and executing code in multiple languages securely.
- SkillIcons.dev: Dynamically renders high-quality SVG icons for the "Tech Stack" section.
- GitHub Open Graph API: Automatically fetches social preview images.
- GitHub Profile Summary Cards: Visualizes real-time GitHub stats.
- LeetCard API: Fetches live LeetCode statistics.
- Brevo (Sendinblue): Powers the secure SMTP email delivery system.
Follow these steps to run the complete DevNexus ecosystem locally.
git clone https://github.com/manasraj/DevNexus.git
cd DevNexus
cd backend
npm install
Create a .env file in the backend folder:
PORT=3000
MONGO_URI=your_mongodb_connection_string
JWT_SECRET=your_super_secret_key
# Email Service (Brevo)
BREVO_API_KEY=your_brevo_api_key
BREVO_SENDER_EMAIL=your_verified_email@gmail.com
# Frontend URL for Redirects
CLIENT_URL=http://localhost:5173
Start the Server:
npm run dev
cd ../frontend
npm install
Create a .env file in the frontend folder:
VITE_API_URL=http://localhost:3000
Start the Client:
npm run dev
DevNexus is fully dockerized. You can spin up the entire stack (Frontend + Backend + MongoDB) with a single command.
docker-compose up --build
The backend exposes a robust REST API. Here are examples of the primary routes:
POST /api/users/login
// Response
{
"id": "65f2...",
"username": "manas",
"email": "manas@example.com",
"token": "eyJhbGciOiJIUzI1Ni..."
}
GET /api/snippets
[
{
"_id": "65f2...",
"title": "Binary Search Template",
"language": "C++",
"code": "int binarySearch(vector<int>& nums, int target) { ... }",
"tags": ["algorithm", "search"]
}
]
POST /api/tasks
// Request Body
{
"content": "Refactor Authentication Middleware",
"isCompleted": false
}
