How can I use headless browsers for performance monitoring?

You can use headless browsers like Puppeteer or Selenium to automate the testing of your web applications. They allow you to simulate user interactions and measure performance metrics like load times.

What specific metrics should I focus on when monitoring performance?

Key metrics include page load time, time to first byte, and resource loading times. You should also consider user-centric metrics like First Contentful Paint (FCP) and Time to Interactive (TTI).

Can I integrate these tools with my CI/CD pipeline?

Yes, you can integrate headless browsers with CI/CD tools like Jenkins or GitHub Actions to automate performance tests during your deployment process.

Are there any best practices for using headless browsers?

Absolutely! Some best practices include running tests in a clean environment, using realistic user scenarios, and regularly updating your testing scripts to reflect changes in your application.
