To reduce initial load time, defer heavy component rendering using Angular 17+ Deferrable Views with the @defer directive. This postpones heavy view work until triggered by viewport entry, user interaction, or hover, preventing unnecessary work during first render.

Viewport-triggered lazy loading defers heavy components like charts and maps until they enter the viewport using the Angular @defer directive with on viewport. This improves time-to-interactive by keeping initial payloads minimal.

Yes, you can load modals and dialogs only when a user action requires them using Angular @defer with when expressions. This interaction-triggered loading prevents heavy components from initializing during first render.

Yes, the Angular @defer directive supports hover-triggered preloading to defer small UI pieces or tooltips until hover. This keeps initial payloads minimal while enabling fast perceived responses for user interactions.

To maintain layout stability and accessibility with lazy loading, provide lightweight placeholder content using the @defer directive's placeholder fallbacks. This ensures the layout remains stable while deferred views load.

Deferrable Views for lazy loading components require Angular 17+ applications. The @defer directive usage patterns, including on viewport, when expressions, on hover, and placeholder fallbacks, are consistent with Angular documentation.
