Book Library – Library Management System

A Java-based library management system with a web frontend, mock API, and backend for business logic.

---

📊 Overview

The Book Library project is designed to manage a library's resources and user interactions. It supports:

• Book Management (CRUD)
• Borrow & Return Transactions
• User (Reader) Management

This was developed as a university/school project to apply Java + Spring Boot for backend, with a TypeScript-based frontend, and a mock API for testing.

├── client/       # Frontend (TypeScript, CSS)
├── mockApi/      # Mock API endpoints for testing frontend
├── server/       # Backend (Java, Spring Boot)
└── database/     # SQL schema and sample data

💡 Technologies Used

• Frontend: TypeScript (possibly React/Angular) + CSS
• Mock API: Node.js or JSON Server
• Backend: Java Spring Boot (Spring MVC, Spring Data JPA)
• Database: MySQL or H2
• Build Tools: Maven or Gradle

---

🗓 Setup & Run

1. Database Setup

• Import database/schema.sql if sample data is provided.
• Configure application.properties or application.yml in server/src/main/resources.

2. Run Mock API

cd mockApi
npm install
npm run start

3. Run Frontend

cd client
npm install
npm run start

The frontend runs on http://localhost:3000 and calls either mock or backend APIs.

4. Run Backend

cd server
mvn spring-boot:run    # or `./mvnw spring-boot:run`

The backend runs on http://localhost:8080.
