Etsy Price Fetcher Cloudflare Workers script

A simple Cloudflare Workers script that augments Etsy product links on a webpage by adding price and quantity information to the link's title attribute.

The script finds all the <a> tags on the page with class='etsy' that links to an Etsy product, and adds title attribute to them with the product's Etsy price and quantity (fetched from Etsy API).

Example anchor link: <a class="etsy external" href="https://www.etsy.com/uk/listing/826425463/puteh-original-drypoint-etching-print?ref=shop_home_active_1"></a>

If the product is not found on Etsy API, then it is assumed that the product link is outdated, and will be removed from the page.

To use:

• Define ETSY_PRICES Cloudflare Workers KV, and add bindings to the CF Worker.
• Register with Etsy API and set the API key as ETSYAPIKEY env var for the CF Worker.
• Enable the Worker script in your Cloudflare zone.

To develop:

• Deploy using Wrangler cli or Cloudflare Workers dashboard or Github Action
