Employee Database Management System
The Employee Management System is a web-based application developed using Node.js, Express.js, and MongoDB to streamline employee data management and operations. It offers comprehensive CRUD functionalities, allowing users to add, view, update, and delete employee records efficiently. The system features a dynamic user interface, leveraging Express.js for HTTP handling and a templating engine like Handlebars.js for rendering. MongoDB ensures robust database integration with support for querying, indexing, and data integrity. Middleware and routing in Express.js manage various functionalities, including error handling and authentication. Designed with modularity in mind, the application maintains a clear structure, separating routes, models, and controllers for easy maintenance and scalability.
Chat Application
To develop a one-on-one real-time chat application, I utilized modern web technologies to ensure seamless communication between users. The primary technology for real-time functionality is Socket.IO, a JavaScript library built on WebSocket that allows for event-driven, bidirectional communication between the server and the client. On the backend, I employed Node.js for its non-blocking I/O and event-driven architecture, making it ideal for real-time applications. Express.js, a lightweight web framework for Node.js, was used to handle routes and serve the frontend files. For the frontend, I implemented HTML, CSS, and JavaScript to design the user interface, ensuring responsiveness and intuitive usability. The application works by first prompting users to enter their username upon opening the interface; this username is stored temporarily on the server using Socket.IO's connection instance.
TelePresence - Collaborative Text Editor
TelePresence is a real-time collaborative document editor designed to provide seamless and dynamic editing experiences by integrating React.js for an interactive user interface, Node.js with WebSockets for real-time backend communication, and MongoDB for scalable and flexible data storage. The platform allows multiple users to join room-based sessions with unique IDs, ensuring private and focused collaboration. Real-time updates synchronize edits instantly across participants, with conflict resolution handled by Operational Transformation (OT) or Conflict-Free Replicated Data Types (CRDTs). User authentication is secured using JSON Web Tokens (JWT), and environment variables safeguard sensitive configurations. Features include text formatting, document saving/exporting, and error handling, with state management tools like Redux or Context API ensuring smooth performance. TelePresence combines cutting-edge technologies to deliver a robust, scalable, and feature-rich platform for efficient and secure collaborative editing.
NewsRoom - GNEWS API
This project utilized the GNews API to dynamically fetch and display four random news articles in English from India, focusing on functionality and design. JavaScript powered API requests and dynamic webpage updates, while logic ensured refreshed articles were non-repetitive. The responsive design, built with CSS Grid, featured a clean layout where each article was displayed as a styled card with a title, description, and link. The "Get News" button allowed users to refresh content and was designed with a modern look, hover effects, and smooth transitions. This project demonstrated the seamless integration of APIs, combining dynamic functionality with thoughtful design for an engaging user experience.
