Goodreads on Amazon

A Chrome extension that shows Goodreads ratings on Amazon and Kitapyurdu book pages.

What it does

• Injects a Goodreads rating + review count next to the book title/byline
• Clicking the rating opens the Goodreads page for the book
• Clicking the review count jumps straight to the community reviews section
• Caches results locally so repeat visits don't re-fetch

Supported sites

• amazon.com.tr — detects book pages via ISBN elements in the product details
• kitapyurdu.com — detects book pages via /kitap/ URL path + ISBN in attributes table

Installation

1. Clone or download this repo
2. Go to chrome://extensions
3. Enable Developer mode
4. Click Load unpacked and select the folder

Files

File	Purpose
manifest.json	Extension config, permissions, host matches
background.js	Fetches Goodreads rating via fetch() (runs in service worker)
content.js	Detects book pages, injects UI, handles caching

Notes

• Only activates on book pages, not search results or category pages
• Goodreads is queried by ISBN (preferred) or ASIN as fallback
• Ratings are cached in chrome.storage.local — clear extension storage to force a re-fetch
