Web crawler and scraper based on Scrapy and Playwright's headless browser.
To use the headless browser specify -p option. Browsers, unlike other standard web request libraries, have the ability to render JavaScript encoded HTML content.
To automatically download and beautify all JavaScript files, including minified ones, specify -dir downloads option - where downloads is your desired output directory.
Future plans:
- check if Playwright's Chromium headless browser is installed or not,
- add option to stop on rate limiting.

Tested on Kali Linux v2024.2 (64-bit).
Made for educational purposes. I hope it will help!
pip3 install --upgrade playwright playwright install chromium
Make sure each time you upgrade your Playwright dependency to re-install Chromium; otherwise, you might get an error using the headless browser.
