🎯 Use Cases

1. Validate Google Alert Queries

Test if your alert queries actually return results:

node scripts/validate-scraping.js docs/google-alerts-broad.md

2. Scrape Search Results

Get actual search results with full details:

node scripts/playwright-scraper.js '"laptop repair" Toronto'

3. Monitor Reddit

Scrape Reddit with human-like behavior:

node scripts/playwright-scraper.js --url "https://www.reddit.com/r/toronto"

4. Custom Scraping

Use the library in your own scripts:

import { humanClick, humanType, humanScroll } from './scripts/human-behavior.js';

🔧 Customization

All behavior parameters are configurable in scripts/scraper-config.js:

mouse: {
  overshootChance: 0.15,      // 15% chance to overshoot
  overshootDistance: 20,       // pixels
  pathSteps: 25,              // bezier curve resolution
}

scroll: {
  minAmount: 100,             // minimum pixels
  maxAmount: 400,             // maximum pixels
  randomDirectionChance: 0.15 // 15% chance to reverse
}

typing: {
  minDelay: 50,               // fastest typing
  maxDelay: 150,              // slowest typing
  mistakeChance: 0.02         // 2% typo rate
}

🧪 Testing

Run the comprehensive test suite:

# With visible browser (recommended for learning)
npm run test:headed

# Headless (faster)
npm test

# Specific test file
npx playwright test tests/human-behavior.test.js --headed

⚠️ Important Notes

Rate Limiting

  • Default delay: 5 seconds between requests
  • Recommended: 10-15 seconds for production
  • Google may still show CAPTCHAs with heavy usage
  • Always respect robots.txt
  • Follow website Terms of Service
  • Use reasonable rate limits
  • Don't overload servers

Best Practices

  1. Start with --headless false to see behavior
  2. Increase delays between requests
  3. Test queries in small batches first
  4. Monitor for CAPTCHAs or rate limiting
  5. Use different IP addresses for high volume

🎓 Learning Resources

  1. Start Here: docs/QUICKSTART_PLAYWRIGHT.md
  2. Full API: docs/PLAYWRIGHT_SCRAPING.md
  3. Examples: scripts/example-usage.js
  4. Tests: tests/human-behavior.test.js
  5. Config: scripts/scraper-config.js

🔜 Next Steps

  1. Install dependencies: npm install
  2. Install browser: npx playwright install chromium
  3. 🎯 Try example: node scripts/example-usage.js 1
  4. 🧪 Run tests: npm run test:headed
  5. Validate alerts: node scripts/validate-scraping.js docs/google-alerts-broad.md
  6. 🚀 Start scraping with confidence!

💡 Tips

  • Headed mode (visible browser) is great for development
  • Headless mode is faster for production
  • Use --max 3 when testing to limit requests
  • Increase --delay if you encounter rate limiting
  • Check console output for detailed behavior logs

🎉 You're Ready!

Your Playwright setup is complete with state-of-the-art bot detection avoidance. All the tools, examples, and documentation you need are in place.

Happy scraping! 🚀
