The Library Management System Using MERN Stack is a web-based application designed to simplify and digitalize everyday library operations. It provides a centralized platform where administrators can manage books, members, and borrowing transactions, while members can browse the book catalog and track their issued books.
This project is developed using MongoDB, Express.js, React.js, and Node.js. It includes separate Admin and Member roles, JWT-based authentication, book availability management, and a responsive user interface. The system helps reduce manual recordkeeping and makes library operations more organized and efficient.

Installation Guide for VS Code
Follow these steps to install and run the Library Management System on your computer.
Step 1: Extract the Project
Download and extract the project ZIP file. Open the extracted project folder in Visual Studio Code.
Step 2: Configure the Backend
Open the VS Code terminal and navigate to the backend directory.
cd backendCreate the environment configuration file.
copy .env.example .envOpen the .env file and configure the MongoDB connection and administrator credentials.
PORT=5000
MONGO_URI=mongodb://127.0.0.1:27017/library_management
JWT_SECRET=replace_with_a_long_random_secret
JWT_EXPIRES_IN=1d
CLIENT_URL=http://localhost:5173
LOAN_DAYS=14
ADMIN_NAME=Library Administrator
ADMIN_EMAIL=admin@example.com
ADMIN_PASSWORD=ChangeThisPassword123!Replace the example JWT secret and administrator password with secure values. Make sure MongoDB is running before starting the backend.
Step 3: Install Backend Dependencies
npm installStep 4: Create the Admin Account
Run the following command from the backend directory to create the administrator account using the configured environment variables.
npm run create-adminUse the configured administrator email and password to sign in. Member registration does not provide administrator privileges.
Step 5: Start the Backend Server
npm run devThe backend API will normally run at http://localhost:5000.
Step 6: Install Frontend Dependencies
Open a second terminal in VS Code and navigate to the frontend directory.
cd frontend
npm installStep 7: Start the Frontend
npm run devOpen the local URL displayed by Vite, normally http://localhost:5173, in your browser. Keep both frontend and backend terminals running while using the application.
How to Use the Project
Admin Role
The administrator can sign in using the account created during setup. The Admin Dashboard provides access to book management, member management, library statistics, and transaction records. Administrators can add new books, update existing records, adjust quantities, deactivate members, and monitor active or overdue loans.
Member Role
Members can register for an account and sign in to the application. They can browse the available book catalog, search by book details, borrow available books, and view their current loans and previous transactions. Members can also check due dates, identify overdue books, and update their profile information.
Project Benefits
- Reduces manual book and member recordkeeping.
- Provides centralized management of library information.
- Improves tracking of borrowed, returned, and overdue books.
- Helps prevent borrowing when no copies are available.
- Separates administrative operations from member activities.
- Provides practical experience with full-stack MERN development.
