How can I use headless browsing for web scraping?

You can use headless browsing to scrape websites without a graphical user interface. Tools like Puppeteer or Selenium are popular for this.

What are the advantages of using headless browsing over traditional scraping methods?

Headless browsing is faster and more efficient since it doesn't render the UI. It also allows for more complex interactions with web pages.

Can you give me a simple example of a headless browser script?

Sure! Here's a basic Puppeteer script:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  const data = await page.evaluate(() => document.body.innerText);
  console.log(data);
  await browser.close();
})();

Are there any legal considerations I should be aware of when scraping?

Yes, always check the website's terms of service and robots.txt file. Some sites prohibit scraping, and violating these can lead to legal issues.
