ReadSphere Library Management System - Backend

Description:

This repository contains the backend of the ReadSphere Library Management System, a web application designed to manage library books, handle book borrowing, and provide user authentication. The backend is built using Node.js, Express, and MongoDB, with RESTful APIs for seamless integration with the frontend.

Key Features

1. Library Book Management

   • Add, edit, and update books.
   • Retrieve all books or filter books by category.
   • Access the latest books with sorting and limit options.

2. Book Borrowing Management

   • Borrow books by users.
   • Retrieve borrowed books by user email.
   • Return books and update the borrowing status.

3. User Authentication Integration JWT Integration

   • Routes designed to integrate with user authentication for personalized data retrieval.

   • The backend uses JSON Web Tokens (JWT) for secure user authentication. Users must register and log in to receive a token, which is then used to access protected API endpoints.

4. Filtering and Searching

   • Filter books by category or retrieve user-specific borrowed books based on email.

5. Database Operations

   • Optimized MongoDB queries with upsert and sorting capabilities.
   • Ensure efficient data handling and avoid duplicate entries with query checks.

.env Setup

To securely manage environment variables, create a .env file in the root of your project and include the following:

PORT = port number DB_USER = username DB_Pass = db pass JWT_SECRET = use your own NODE_ENV = development
