Scrapy Scraper
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.
