fix: ShopFiber24 sitemap-based scraping + Fibermall image extraction
ShopFiber24 (fiber24.ts): - Complete rewrite: was using JS-rendered catalog (all prices = 0) - New strategy: fetch sitemap_0.xml.gz → 310 product DE-URLs - Each product page has Schema.org microdata: itemprop=price, sku, image - Extracts: price (minPrice), SKU, image_url, name, specs - Rate: 1 req/1.5s, no Playwright needed FiberMall (fibermall.ts): - Add imageUrl to Product interface - Extract first fibermall.com/photo/*.jpg from product listing card - Write image_url to transceivers table (has_image=true) on upsert - SKU variants share parent product image - 304 FiberMall transceivers will get images on next scraper run

* ShopFiber24 Scraper — German compatible transceiver shop
|
||||
*
|
||||
* shop.fiber24.net — EUR prices, FO transceiver category.
|
||||
* Paginated catalog: /FO-TRANSCEIVER/de?p=N
|
||||
*
|
||||
* Rate limited: 1 req/2sec.
|
||||
* Strategy: The catalog page is fully JS-rendered (BMS/JTL shop system).
|
||||
* Product detail pages DO have static Schema.org microdata with real prices.
|
||||
*
|
||||
* Approach:
|
||||
* 1. Fetch sitemap_0.xml.gz → extract all /de product URLs
|
||||
* 2. Filter transceiver/optics URLs (keyword match)
|
||||
* 3. Fetch each product page → parse itemprop microdata (price, sku, image)
|
||||
* 4. Upsert transceiver + price_observation + image_url
|
||||
*
|
||||
* Rate limited: 1 req/1.5 sec.
