What are some examples of headless browser automation?
Headless browser automation allows you to run web browsers without a graphical user interface. Examples include using Puppeteer with Chrome, Selenium with Firefox, and Playwright for cross-browser testing.
Can you explain how Puppeteer works?
Puppeteer is a Node.js library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It can be used for tasks like web scraping, automated testing, and generating screenshots.
What are the advantages of using headless browsers?
Headless browsers are faster and consume less memory since they don't render a UI. They are ideal for automated testing and scraping tasks.
Are there any limitations to using headless browsers?
Yes, some limitations include challenges with debugging, potential differences in rendering compared to full browsers, and issues with websites that rely heavily on JavaScript.
