What are headless browsers and how can I integrate them into my project?

Headless browsers are web browsers without a graphical user interface. They are used for automated testing, web scraping, and more. You can integrate them using libraries like Puppeteer or Selenium.

Can you give me an example of using Puppeteer for web scraping?

Sure! Here's a simple example:

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(() => {
    return document.querySelector('h1').innerText;
  });
  console.log(data);
  await browser.close();
})();

What are the advantages of using headless browsers over traditional browsers?

Headless browsers are faster and consume less memory since they don't render a UI. They're ideal for automated tasks and testing.

Are there any limitations I should be aware of?

Yes, some limitations include lack of visual feedback, potential issues with JavaScript-heavy sites, and debugging can be more challenging.
