What is headless browsing and how can I use it?

Headless browsing is a way to interact with web pages without a graphical user interface. It's often used for automated testing or web scraping.

What tools can I use for headless browsing?

Popular tools include Puppeteer, Selenium, and Playwright. They allow you to control a browser programmatically.

Can you give me an example of a simple headless browsing script?

Sure! Here's a basic Puppeteer script that opens a page and takes a screenshot:

const puppeteer = require('puppeteer');

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

Are there any limitations to headless browsing?

Yes, some websites may block headless browsers, and debugging can be more challenging without a GUI.
