Bookstore API Backend with FastAPI

This project demonstrates a sophisticated backend API for a Bookstore application, built using FastAPI, a modern, fast (high-performance) web framework for building APIs with Python. The API provides features for managing books and authors, including full CRUD operations, JWT-based authentication, database integration using SQLAlchemy, and pagination. It also includes automated seeding of the database with fake data for testing purposes.

Introduction

The Bookstore API provides a secure and scalable backend service for managing books and authors in a bookstore. It demonstrates key backend development concepts using FastAPI, such as asynchronous endpoints, JWT authentication, and database integration with SQLAlchemy. The API is designed to be easily extended and deployed, making it a great starting point for more complex applications.

Features

• JWT Authentication: Secure API endpoints with JSON Web Tokens for authentication.
• CRUD Operations: Full Create, Read, Update, Delete operations for books and authors.
• Database Integration: Persistent storage using SQLite with SQLAlchemy ORM.
• Async Endpoints: Asynchronous endpoints for improved performance.
• Pagination: Efficient handling of large datasets with pagination.
• Error Handling: Graceful error handling with meaningful HTTP status codes and messages.
• Modular Structure: Organized codebase with multiple files for scalability and maintainability.
• Automated Database Seeding: Use of Faker library to generate and seed the database with fake data.
