How do I set performance budgets?

The skill utilizes assertions within the lighthouserc.json file to set minimum scores and maximum numeric values for specific performance metrics.

Can I use this skill to automate performance tests in GitHub Actions?

Yes, this skill includes specific templates and configurations for integrating Lighthouse CI and Playwright into GitHub Actions workflows.

Does it support mobile performance testing?

Yes, the skill provides configurations for simulating mobile devices and slow network conditions like 3G to ensure performance across all user segments.

What is the difference between RUM and Synthetic Monitoring?

RUM tracks real user experiences in the wild, while Synthetic Monitoring uses controlled lab environments to proactively catch issues before they affect users.

Which performance metrics can I track?

It focuses on Core Web Vitals like Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), along with TTI, Total Blocking Time, and custom navigation timing.

Analíticas y Monitorización

Implements automated performance testing and proactive monitoring using Lighthouse CI and Playwright to ensure consistent site speed and health.

Acerca de

The Synthetic Monitoring skill empowers developers to establish proactive performance gates within their CI/CD pipelines and scheduled environments. It provides standardized configurations for Lighthouse CI to audit Core Web Vitals, custom Playwright scripts for transaction-based performance testing, and integration patterns for scheduled monitoring platforms. By moving from reactive real-user monitoring to proactive lab testing, teams can catch performance regressions before they reach production, maintaining high scores for Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and overall site responsiveness.
