IDURAR is a free, open-source ERP and CRM application built on the MERN stack (MongoDB, Express.js, React.js, Node.js) with Ant Design and Redux. It provides modules for invoice management, payment processing, quote generation, customer relationship management, inventory tracking, and financial reporting. The system features multi-language support (44 languages), PDF generation for business documents, role-based access control, and a responsive user interface. The architecture separates concerns with a RESTful API backend and a modular frontend utilizing React, Redux for state management, and Ant Design for UI components.
The Hostel Management system is a MERN stack application designed for managing student hostels. It features user authentication (login, registration, profile management), student CRUD operations, attendance tracking by room, and analysis views with CSV export capabilities. The frontend is built with React and Redux, utilizing React-Bootstrap for UI components, while the backend uses Node.js with Express and MongoDB for data storage, secured with JWT-based authentication. The architecture follows a traditional client-server model. The frontend communicates with the backend via RESTful API endpoints. Key modules include authentication middleware, token generation utilities, and reusable UI components such as a search box and form container. The system allows administrators to manage users and students, while regular users can view and update their profiles and attendance. Despite functional implementation, the codebase exhibits some areas for improvement, including missing dependency declarations in React hooks (leading to potential stale closures) and tight coupling in certain components. However, the core functionality is sound, and the system demonstrates competent full-stack development practices suitable for a small to medium-sized application.
