Frappe HRMS is a full-featured Human Resource and Payroll management system built as a Frappe/ERPNext application. It covers the complete employee lifecycle including recruitment, onboarding, attendance and shift management, leave administration, payroll processing, expense claims, performance appraisals, and separation. The system provides both a desktop interface via the Frappe framework and a mobile-first Progressive Web App (PWA) built with Vue.js and Ionic for employee self-service. A separate roster application handles shift scheduling and assignment. The architecture follows Frappe's monolithic pattern with custom DocTypes, server-side Python controllers, client-side JavaScript, and extensive reporting. Payroll processing is a key strength, supporting salary structures with formula-based components, tax slabs, multi-currency, gratuity, and benefit claims. The codebase demonstrates strong engineering practices with comprehensive test coverage, data migration patches across versions, and reusable patterns such as safe formula evaluation, immutable leave ledger entries, and push notification mixins. It integrates tightly with ERPNext for accounting entries and payment processing.
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.
