ScyllaDB Bookshop

Overview

The ScyllaDB Bookshop is a web application that utilizes the Google Books API to fetch a list of books and allows users to add/remove books from their shopping cart, modify quantities, and calculate the total price. The frontend is built using React.js, while the backend is implemented in Go to serve the application and log user requests.

Inside the /backend folder rename the

env.example

into

.env

and then run

Backend

cd backend
docker-compose -f docker-compose.dev.yml up --build

Features

Main Page

• Displays a list of books fetched from the Google Books API.
• Each book includes a thumbnail image, title, page count, and listed price.
• Users can click "Add to Cart" to add a book to their shopping cart.
• If the book is already in the cart, clicking "Add to Cart" again does nothing.

Shopping Cart

• A "My Cart" button displays the number of items in the cart.
• Clicking "My Cart" shifts the book list left and displays the cart contents.
• Each cart item includes:
  • A remove button (X) to delete the book from the cart.
  • An input field to update the quantity.
  • If the quantity is invalid (not between 1 and 100), an error message appears.
• A total price box calculates the sum of all cart items (only displayed when items are in the cart).

Backend (Go Server)

• The app is served from a Go server.
• All user traffic is routed through the server and logged.
• Books responses are filtered by "maturityRating": "NOT_MATURE".
• If an ISBN is provided, the Open Library API is used to fetch the revision number (if greater than 1).

Bonus Features

• Persistence: Shopping cart data persists between page refreshes.
• Filtering: Users can filter books by title.
• Testing: Includes basic unit and functional tests.
• Dockerization: Supports Docker for easy deployment.
