This skill empowers developers to integrate Real User Monitoring (RUM) into their web applications, providing a vital bridge between raw performance data and actual user experiences. It guides users through the entire lifecycle of performance observability, from selecting the right platform and designing an instrumentation strategy to implementing the JavaScript tracking code required for Core Web Vitals and custom performance events. By focusing on real-world data rather than synthetic benchmarks, this skill ensures that performance optimization efforts are targeted and effective.
