NITM MessTrack Portal

An industry-standard, secure, database-backed web application built for NIT Meghalaya (NITM) to track student mess fees, manage leaves, and automate meal refund calculations. This system replaces Excel sheets and manual paperwork with a centralized digital ledger.

🚀 Key Features

🏢 Panel Separation & Role-based Access

• Admin Dashboard: Overview of system statistics (active/leave students, net revenue, total refunds) with comprehensive search, filters, visual charts, and settings.
• Student Portal: Locked access allowing students to view their profile, mess fee payments, refund history, and apply for leaves.

📝 Mess & Leave Lifecycle Management

• Student CRUD: Complete management for adding, editing, deleting, and searching student records.
• Leave CRUD & Math: Missed meals (Breakfast, Lunch, Dinner) are tracked. Leave refunds are automatically calculated in real-time based on customizable meal rates and semesters.
• History Logs: Automated database triggers to adjust student refundEarned balance on leave creation, modification, or cancellation.

⚡ Smart UI Automations

• Email Autofill: Typing a student's roll number (e.g., B24CS038) automatically generates their institutional email (b24cs038@nitm.ac.in) in lowercase.
• Fee Mirroring: The paid fee amount is mirrored automatically from the mess fee during manual student addition.
• DOB Password Mapping: Date of Birth is a required field; the student portal password dynamically hashes the DOB, so changing the DOB updates their login password.

⚙️ Local Development Setup

Prerequisites

Ensure you have Node.js (v18+) and npm installed.

---

Step 1: Clone & Install Dependencies

1. Install root (frontend) dependencies:

   npm install

2. Install backend dependencies:

   cd backend
   npm install

---

Step 2: Configure Environment Variables

Create a .env file in the backend folder:

PORT=5000
NODE_ENV=development
DATABASE_URL="file:./dev.db"
JWT_SECRET="super-secret-key-12345-nitm-messtrack-app-production-key"

---

Step 3: Initialize the Database

1. Run Prisma database migrations to create local SQLite tables:

   npx prisma migrate dev --name init

2. Seed settings, default hostels, and initial student profiles:

   npm run prisma:seed

---

Step 4: Run the Application

1. Start the Backend API Server: Navigate to the backend/ folder and run:

   npm start

   The backend will boot up at http://localhost:5000.

2. Start the Frontend Client: Navigate to the project root and run:

   npm run dev

   Vite will start the client application (usually at http://localhost:5173 or http://localhost:5174).
