Optimize Angular performance by applying route-level lazy loading to split code and ChangeDetectionStrategy.OnPush to reduce rendering cycles, directly improving Core Web Vitals and overall application smoothness.

Handle heavy rendering costs for large lists in Angular by implementing CDK virtual scrolling, which renders only visible items, and applying trackBy functions to minimize DOM manipulations during updates.

Improve Core Web Vitals like LCP and INP in Angular by applying end-to-end performance patterns including route-based code splitting, NgOptimizedImage for responsive assets, and OnPush change detection.

Yes, you can use NgOptimizedImage in existing Angular projects to optimize images and assets with responsive sizing, which helps improve Largest Contentful Paint and overall perceived performance.

Angular applications often have large initial bundle sizes due to a lack of route-level code splitting; applying lazy-loaded routes reduces the initial payload by loading feature modules only when needed.

You need trackBy functions in Angular templates when rendering large lists or complex collections, as they optimize rendering efficiency by tracking item identities and preventing unnecessary DOM re-renders.
