Optimize Angular images by using NgOptimizedImage with ngSrc, correct dimensions, and priority for LCP elements. This reduces slow initial rendering and improves loading stability for image-heavy UIs.

The best way to lazy load Angular components is using @defer with viewport, interaction, idle, or timer triggers. This defers non-critical feature areas while providing placeholder, loading, and error states to reduce initial bundle size.

Angular SSR and hydration improve SEO and startup time by rendering pages on the server before client hydration. Selecting appropriate SSR or SSG strategies based on page intent reduces sluggish initial rendering and improves search indexing.

Angular runtime jank and layout thrash occur when reflows and repaints are triggered inside lifecycle hooks. Avoid manipulating DOM layout during these events and use lazy routes to keep performance-friendly rendering stable.

Yes, you can use lazy routes to reduce Angular initial bundle size. Loading components and feature modules on demand speeds up navigation and ensures heavy feature areas only load when accessed.

Use @defer triggers instead of standard loading for heavy feature areas that should load on demand. Triggers like viewport, interaction, idle, or condition delay rendering until necessary, reducing initial load overhead.
