Ethical Web Scraping Project (Python)

📌 Overview This project demonstrates three types of ethical Python web scrapers:

• Static scraping** using BeautifulSoup
• Scalable scraping** using Scrapy
• Dynamic JS scraping** using Playwright

All scripts are designed with built-in middleware to respect ethical and legal constraints, including robots.txt, User-Agent transparency, and rate limiting.

📁 Project Structure

web_scraping_project/ ├── beautifulsoup_scraper.py # Static HTML scraper ├── scrapy_spider.py # Asynchronous crawler with Scrapy ├── playwright_scraper.py # Dynamic scraper with Playwright ├── ethical_mw.py # Middleware enforcing ethical rules ├── requirements.txt # Python dependencies ├── README.md # Project documentation

⚙️ Setup Instructions

1. Clone or download this repository.
2. Install required packages:

bash pip install -r requirements.txt playwright install # Needed for browser automation

For Jupyter Notebook users: python import nest_asyncio nest_asyncio.apply()

🚀 Running the Scrapers -BeautifulSoup Scraper:python beautifulsoup_scraper.py -Scrapy Spider:scrapy runspider scrapy_spider.py

• Playwright Scraper:python playwright_scraper.py

✅ Ethical Middleware Highlights (ethical_mw.py)

• Respects robots.txt (via urllib.robotparser)
• Delays requests (rate limit = 1/sec)
• Custom User-Agent: identifies scraper with contact URL/email
• Logs scraping actions (can be extended to database or file)

📚 Research Context This project supports the academic paper: “Advanced Web Scraping with Python: Ethical, Legal, and Technical Challenges” It benchmarks popular scraping tools and proposes best practices for responsible automation.
