Evaluating React Application Performance with a Sip of RUM
watch on portal.gitnation.org ↗https://portal.gitnation.org/contents/evaluating-react-application-performance-with-a-sip-of-rumsummary
Coverage of using OpenTelemetry and Real User Monitoring (RUM) to find performance bottlenecks in React apps, showing front-end tracing and basic metrics (including an example HTTP POST trace with pathway and timing). Explains observability pillars—logs, metrics (throughput, latency, Core Web Vitals), and traces—notes React client instrumentation is experimental, and describes RUM as a complementary way to capture metrics OpenTelemetry currently lacks.
