This Python script performs web scraping on a website to extract links, emails, and WhatsApp links from the specified domain (stei.itb.ac.id). It uses the requests library to fetch web pages and BeautifulSoup for parsing HTML content.

1. Ensure you have the required libraries installed:

   pip install requests beautifulsoup4

2. Modify the script to specify the target domain (DOMAIN), home URL (HOME_URL), and other settings as needed.

3. Run the script:

   python script.py

4. The script will perform the following actions:

   • Visit the home URL (HOME_URL) and extract all links from the specified domain (DOMAIN).
   • Collect email addresses (mailto: links) and WhatsApp links (api.whatsapp.com).
   • Save the extracted data to separate log files (scrape-links-stei.log, scrape-email-stei.log, scrape-whatsapp-stei.log).

5. The script will recursively follow links within the specified domain to gather additional URLs.

6. The extracted links, emails, and WhatsApp links will be saved in their respective log files.

• You can modify the HOME_URL, DOMAIN, TIMEOUT, or other settings in the script to target different websites or adjust the scraping behavior.

• To specify a different starting URL, change the value of HOME_URL in the script.

• Extracted links from the specified domain are saved in scrape-links-stei.log.
• Extracted email addresses are saved in scrape-email-stei.log.
• Extracted WhatsApp links are saved in scrape-whatsapp-stei.log.
