📍 Overview

This repository houses the backend for the Efficient Library Digital Management System MVP. This system streamlines library operations by providing a robust backend system for managing library resources, handling user authentication and authorization, processing borrowing requests, and tracking due dates. The tech stack includes FastAPI, Python, PostgreSQL, and leverages custom LLMs like Gemini and OpenAI.

📦 Features

	Feature	Description
⚙️	Architecture	The system uses a modular architecture with separate modules for authentication, book management, and user management, ensuring ease of development and maintenance.
📄	Documentation	This README file provides a detailed overview of the MVP, its dependencies, and instructions on how to set up and run the system.
🔗	Dependencies	The project relies on external libraries such as FastAPI, SQLAlchemy, psycopg2, and Pydantic for efficient development and robust data handling.
🔐	Security	The system implements security measures, including JWT authentication for secure access and data validation to prevent vulnerabilities.
⚡️	Performance	The system optimizes performance by leveraging FastAPI's high-performance capabilities, efficient database queries, and appropriate data structures.
📶	Scalability	The system is designed for scalability, utilizing a robust database like PostgreSQL and efficient architecture to handle increasing user load and data volume.
🔌	Integrations	The system can integrate with external APIs like OCLC or Worldcat for retrieving bibliographic data and external authentication systems.
🧪	Testing	Unit tests are included to verify the correctness and robustness of the authentication, book management, and user management logic.
🔀	Version Control	The project utilizes Git for version control and employs a robust CI/CD pipeline for automated builds and deployments.

💻 Installation

🔧 Prerequisites

• Python 3.9+
• PostgreSQL 15+
• Docker (recommended)

🚀 Setup Instructions

1. Clone the repository:

   git clone https://github.com/coslynx/Library-Digital-Management-System-MVP.git
   cd Library-Digital-Management-System-MVP

2. Create a virtual environment:

   python -m venv .venv
   source .venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Configure environment variables:
   • Create a .env file in the project root directory.
   • Copy the .env.example file and replace the placeholder values with your actual configuration:

     DATABASE_URL=postgres://user:password@host:port/database
     JWT_SECRET=your_secret_key
     HOST=0.0.0.0
     PORT=8000
     DB_HOST=localhost
     DB_PORT=5432
     DB_USER=user
     DB_PASSWORD=password
     DB_NAME=database
     

🏗️ Usage

🏃‍♂️ Running the MVP

1. Start the database (using Docker Compose):

   docker-compose up -d database

2. Start the backend server:

   uvicorn api.main:app --host $HOST --port $PORT --reload

3. Access the API:
   • The API is now accessible at http://localhost:8000 (or the specified port in .env).

⚙️ Configuration

• .env file: This file contains environment variables for configuring the database connection, JWT secret key, server host and port, and other settings.
• Database Configuration:
  • Ensure that the database is running and configured correctly.
  • Update the DATABASE_URL environment variable with your database credentials.
• JWT Secret Key:
  • Create a strong secret key for JWT token generation and store it in the JWT_SECRET environment variable.

📚 Examples

• Register a new user:

  curl -X POST http://localhost:8000/api/register \
  -H "Content-Type: application/json" \
  -d '{"username": "newuser", "email": "user@example.com", "password": "securepass123"}'

• Login an existing user:

  curl -X POST http://localhost:8000/api/login \
  -H "Content-Type: application/json" \
  -d '{"email": "user@example.com", "password": "securepass123"}'

• Search for a book:

  curl -X GET http://localhost:8000/api/books?title=The%20Hobbit
