Optimize Angular 20 performance by refactoring components to use Signals for state management and efficient change detection. This approach replaces manual change detection triggers, resulting in faster rendering and a more responsive user experience.

Reduce bundle size by implementing lazy loading and utilizing the @defer block for heavy child components. Deferring non-critical component rendering significantly improves initial load performance in Angular 20+ applications.

httpResource streamlines data fetching optimization by integrating resource loading directly with Angular's Signals architecture. It replaces complex RxJS observables for standard HTTP requests, yielding cleaner service refactoring and efficient data retrieval.

Yes, the optimization guidelines fully support native control flow syntax. Leveraging built-in control flow alongside signal inputs and outputs ensures modern, efficient template rendering without relying on deprecated structural directives.

Use @defer blocks when you need to conditionally render heavy child components on interaction or viewport entry, rather than routing-based lazy loading. This minimizes initial bundle parsing and improves initial load performance.
