This skill facilitates the end-to-end setup of Real User Monitoring (RUM) for web applications, enabling developers to capture actual performance data from live users. It provides expert guidance on selecting appropriate RUM platforms like Datadog or New Relic, designing instrumentation strategies for Core Web Vitals, and generating the necessary tracking code for custom performance events. By monitoring metrics such as Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), this skill helps teams identify performance bottlenecks and improve overall site responsiveness based on real-world usage patterns rather than synthetic tests.
