How can I use Puppeteer for data extraction?

You can use Puppeteer to automate browser tasks and extract data from web pages. What specific data are you looking to extract?

I want to scrape product information from an e-commerce site.

You can navigate to the product page, select the elements containing the data, and use Puppeteer's methods to extract the text. Do you need help with the code?

Yes, please provide a sample code snippet.

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/products');
  const products = await page.evaluate(() => {
    return Array.from(document.querySelectorAll('.product')).map(product => ({
      title: product.querySelector('.title').innerText,
      price: product.querySelector('.price').innerText
    }));
  });
  console.log(products);
  await browser.close();
})();

This will log an array of product titles and prices.
