webshop-scraper

Command line scraper for orders and item info from webshop(s)

This project was separated from it's parent project Homelab Organizer (having outgrown it), a web-based tool (Django) for keeping control of items and tools in your homelab.

Output

Output from finished scrapers consists of one JSON and a ZIP in a subfolder of the output/ folder.

The JSON file will follow the JSON schema defined in output/schema.json. Any extra data avaliable for the order or items will be added as keys to this file. All paths are relative to the root of the accompanying ZIP file.

Requirements

Python 3.10 or later. Should support both Linux and Windows.

Requires Firefox installed (not from snap, see instructions), and a profile setup for the scraping.

Creating and configuring a separate Firefox profile

Run

firefox -p

Create a new profile, named i.e. selenum. In the examples below you named the profile selenium, and your username is `awesomeuser``.

Find the path to the profile, you can start looking in these paths:

  • Windows: C:\Users\awesomeuser\AppData\Roaming\Mozilla\Firefox\Profiles\SOMETHINGRANDOM.selenium1
  • Linux / Mac: /home/awesomeuser/.mozilla/firefox/SOMETHINGRANDOM.selenium1

Add this path to the WS_FF_PROFILE_PATH_WINDOWS/LINUX/DARWIN config variable in .env.

Installing Firefox outside of Snap on Ubuntu

Firefox installed as a snap on Ubuntu is not supported.
To change to a apt install on i.e. Ubuntu 22.04, read this article for omg!ubuntu.

Scrapers

Adafruit

Tested on three orders, 28 items.

  1. Login to https://www.adafruit.com/
  2. Click "Account" -> "My Account"
  3. Click "Order History" (https://www.adafruit.com/order_history)
  4. Click "Export Products CSV" and save "products_history.csv"
  5. Click "Export Orders CSV" and save "order_history.csv"

Run the command too see where you should put the files.

python scrape.py adafruit

python scrape.py adafruit --to-std-json

Aliexpress

Tested on 229 orders, 409 items

Scrapes order list, item info and details to JSON, and saves a PDF copy of the Aliexpress item snapshot.

Aliexpress has a really annoying CAPTCHA that failes even if you do it manually, as long as the browser is automated.

To bypass this, open your selenium firefox profile, and log in to Aliexpress manually before each scraping session.

Try not to resize or move the autmomated browser window while scraping. You will be prompted if you need to interract, i.e. accept a CAPTCHA. If you happen to watch and see that a page is "stuck" and not loading, you can try a quick F5.

If you want to download some and some orders, you can start with i.e. WB_ALI_ORDERS_MAX=10, and then increment with 10 for each run. Remember to use --use-cached-orderlist so you do not have to scrape the order list every time.

python scrape.py aliexpress --use-cached-orderlist

python scrape.py aliexpress --to-std-json

Polyalkemi.no

Only tested on two orders.

This scraper supports the arguments

  • --skip-item-thumb
  • --skip-item-pdf
  • --skip-order-pdf

for scraping and export.

They will skip storing the item thumbnail, item PDF print, and order invoice while scraping and exporting.

It also supports the and the option

  • --include-negative-orders

for export. It will include negative orders (returns) in the export.

python scraper.py polyalkemi 

python scraper.py polyalkemi --to-std-json

Kjell.com

Tested on 53 orders, 191 items.

Currently only supports the norwegian shop front. (Swedish testers welcome!)

python scraper.py kjell

python scraper.py kjell --to-std-json

Amazon

Tested on TLDs (orders/items):

  • .de 59/210
  • .com 12/15
  • co.uk 8/11
  • co.jp 2/2
# Scrape this year and archived orders orders on amazon.de
python scrape.py amazon --tld de --use-cached-orderlist

# Scrape orders from 2021 and 2023 on amazon.es
python scrape.py amazon --use-cached-orderlist --year 2021,2023 --not-archived --tld es

# Scrape all orders on amazon.co.jp from 2011 onwards, including archived orders
python scrape.py amazon --use-cached-orderlist --start-year 2022 --tld co.jp

# See help for details
python scrape.py --help

# Export scraped data for amazon.de
python scrape.py --tld de --to-std-json

Komplett.no

Tested on 80 orders, 155 items.

Make sure to log in Komplett using the selenium Firefox profile BEFORE starting scraping.

Komplett has a weird scrape detector, that makes Firefox give weird transport/TLS errors. If this happens, the script should tell you to clear all the profile data (only komplett.no is not enough) and re-login to Komplett.no. If this happens you should be able to continue from where you left.

python scraper.py komplett

python scrape.py komplett --to-std-json

Acknowledgements

For steadfast bug fixing, having orders that totally scramble my scraping, and coming up with those excellent ideas when I have been struggling with a bug for an hour.

Why

  • Am i using Firefox and not Chrome/Other?

    • Efficiently printg to PDF is much easier in Firefox. Chorome does also not appear to give actual text in PDFs after printing as Firefox does.

  • Am i not using webdriver.print_page to get a PDF?

    • In testing it created redonkulously large PDFs. We are talkin 40-60 MB when printing via Mozilla/Microsoft printers created sub 10MB PDFs
