How can I use Puppeteer for advanced web scraping?

You can use Puppeteer to automate browser actions and scrape data from websites. What specific features are you interested in?

I want to handle dynamic content and pagination.

For dynamic content, you can wait for specific elements to load using page.waitForSelector(). For pagination, you can loop through pages and extract data.

Can you show me a code example for that?

Sure! Here's a basic example:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');

  // Wait for the content to load
  await page.waitForSelector('.dynamic-content');

  // Scrape data
  const data = await page.evaluate(() => {
    return Array.from(document.querySelectorAll('.item')).map(item => item.textContent);
  });

  console.log(data);
  await browser.close();
})();

This will scrape items from a page after the dynamic content loads.
