kompress e-shop scrape

Snapshot of the live catalogue at http://e-shop.kompress.sk (PrestaShop 1.5/1.6), taken 2026-07-29. Only the product catalogue is captured — no CMS pages, no orders.

Re-run with python3 scrape.py (stdlib only, no dependencies). It is idempotent: already-downloaded images are skipped.

Files

File	Contents
`categories.json`	30 categories, flat list ordered parent-before-child
`products.json`	118 products, ordered by PrestaShop id
`images/<product_id>/<image_id>.jpg`	181 product images, original uploads
`images/categories/<category_id>.jpg`	30 category thumbnails, original uploads

Category schema

{
  "id": 8,                     // PrestaShop id_category, kept as the stable key
  "name": "Gáza, role, štvorce, prírezy",
  "title": "…",                // link title attr; often a longer marketing blurb
  "url": "http://e-shop.kompress.sk/8-gaza-role-…",
  "parent_id": 7,              // null for top-level
  "path": ["Zdravotnícke", "Gáza, role, štvorce, prírezy"],
  "depth": 1,                  // 0 = top level
  "description_html": "<p>…</p>",
  "description": "…",          // plain-text rendering
  "image": { "url": "…/img/c/8.jpg", "file": "images/categories/8.jpg" },
  "product_ids": [59, 62, …],
  "product_count": 8
}

The tree is 2 levels deep: 3 roots (Zdravotnícke, Somatické, Pre invalidov), 27 children. The roots hold a few products directly; Somatické and Pre invalidov hold none of their own.

}

breadcrumb/category_path is the product's primary category trail. categories lists every category the product is actually listed in — 7 products appear in more than one, so treat product↔category as many-to-many.

Variants

20 of the 118 products sell in several sizes/packagings — 74 combinations in total, across 4 attribute groups: Rozmer, Veľkosť, Balenie, Počet útržkov v balení. Each is its own purchasable unit with its own code, price and stock, so these map to product_variants rather than to plain products.

"attribute_groups": [
  { "id": 4, "name": "Rozmer", "slug": "rozmer",
    "attributes": [ { "id": 21, "label": "10cm x 10cm", "default": false }, … ] }
],
"variants": [
  {
    "id": 30,                          // id_product_attribute
    "attribute_ids": [23],
    "label": "5cm x 5cm",              // groups joined with " / " when there are several
    "attributes": [{ "group": "rozmer", "label": "5cm x 5cm" }],
    "reference": "1211",               // per-variant Kód; "" on some products
    "quantity_available": 500,
    "price_impact_tax_excluded": -2.35,
    "price_tax_excluded": 1.04,
    "price": 1.14,                     // tax included — what the shop shows when selected
    "minimal_quantity": 1,
    "image_id": 100,                   // null when the variant has no own image
    "is_default": true
  }
]

price is computed as (product.price_tax_excluded + price_impact_tax_excluded) * (1 + tax_rate/100), matching themes/default/js/product.js. Verified: every product's displayed price equals its default variant's computed price, and every product's quantity_available equals the sum of its variants' stock.

On variant products the top-level price/reference describe the default variant, and quantity_available is the total across variants. 14 of the 74 variants have an empty reference.

Images

images[].url points at PrestaShop's untouched original upload (/img/p/<digits split by slash>/<image_id>.jpg), not a generated thumbnail. For product 73 that is 53 KB versus 10 KB for the -large_default the page shows. Every downloaded file was verified to be a real JPEG; sizes run 3 KB – 634 KB.

Product 270 (Plachta na posteľ z PVC) has no image in the shop at all — its images array is empty and default_image_id is null.

Coverage notes

Product URLs came from crawling every category listing, unioned with sitemap.xml. All category listings fit on a single page, so nothing was lost to pagination.
sitemap.xml is stale: it advertises 182 products, but 83 of those (ids 8–55, 72, 86, 96, 103–105, 109, 118–197 among them) return HTTP 404 — they are disabled/deleted products, verified individually via index.php?id_product=<id>&controller=product. 118 live products remain.
Some products are served under both an old and a new slug (e.g. product 59 as …59-gaza-hydrofilna-skladana-zlozky-z-gazy.html and …59-gaza-hydrofilna-skladana.html). These are deduplicated by id, keeping the URL the category listing links to.
29 products have an empty top-level reference — that is genuine, the shop leaves the Kód field blank for them (the block is rendered display:none). 20 of those 29 12 of those 29 are variant products, where the code lives on each variant instead.
