Core Web Vitals: How to make your angular app feel like a dream
summary
Explains concrete thresholds and fixes: LCP <2.5s is good, 2.5–4s needs work, >4s is poor; CLS <0.1 good, 0.1–0.25 needs work, >0.25 poor; INP <200ms good, 200–500ms needs work, >500ms forces a JS rewrite. Shows measurement with web-vitals.js, Lighthouse and RUM (e.g. Datadog) and lab vs field data, and practical fixes for Angular: preload / preload as, defer/deferrable views and ngComponentOutlet plus ngOptimizedImage, control flow, runOutsideAngular / experimental withoutNgZone and setTimeout/microtask patterns.
