This tutorial extends the SSR explained on Server-side rendering (SSR) with Angular Universal page. This tutorial fixes the content flash occurs on SSR write after page loads due to content refresh caused by data received through network requests. If you are crazy about PageSpeed/Web Vitals score as much as me, this will help you to improve: Largest Contentful Paint (LCP) First Input Delay (FID) Cumulative Layout Shift (CLS) I have tested this on Angular 9 and 10.
