Angular Universal enables server-side rendering. The server pre-renders HTML, so users see content faster and crawlers index better. Benefits: improved First Contentful Paint, better SEO, and graceful loading on slow devices. The client later hydrates to a full SPA.

Interpolation `{{ expr }}` outputs text into the DOM (e.g., inside a `<p>`). Property binding `[prop]="expr"` sets a real DOM property (e.g., `[value]`, `[src]`, `[disabled]`). Interpolation is for text nodes; property binding affects element behavior and attributes.
Use OnPush when your component inputs are immutable or you update state by replacing object references. It reduces checks to when inputs change, events fire from the component, or an observable emits via async pipe.
@Component({ changeDetection: ChangeDetectionStrategy.OnPush })Guards can return a UrlTree to redirect without side effects. Subscribe to router.events and handle NavigationError for global logging. In guards/resolvers, map server errors to a safe UrlTree (e.g., /error) to avoid half-rendered screens.
canActivate(): Observable<boolean|UrlTree> {
return this.api.isAllowed().pipe(
map(ok => ok || this.router.createUrlTree(['/forbidden'])),
catchError(() => of(this.router.createUrlTree(['/error'])))
);
}
this.router.events.subscribe(e => {
if(e instanceof NavigationError){ /* report */ }
});Prefer pure pipes over calling methods in bindings to avoid extra change detections. Use trackBy with *ngFor to prevent re-rendering unchanged items. Keep heavy logic in the component, not the template. Avoid deep async chains—use async pipe or resolvers. Split large templates into smaller presentational components.
