routerLink is a declarative directive used in templates for anchor navigation, which also updates active link styling. router.navigate() is an imperative API used from code (e.g., after a save) to navigate programmatically with extras like query params and state.
<a [routerLink]="['/orders', order.id]"></a>
// TS
this.router.navigate(['/orders', id], { queryParams: { tab: 'items' } });Use @Input/@Output for parent↔child communication in a component hierarchy. Use router extras (queryParams, state) for cross-feature navigation or when no direct parent-child relationship exists. Router state is not persisted on hard refresh; URL params are shareable/bookmarkable.
// programmatic navigation with state
this.router.navigate(['/checkout'], { state: { cartId } });
// in target component
const cartId = history.state?.cartId;Emulated (default) scopes styles to the component by adding unique attributes—good balance of isolation and compatibility. ShadowDom uses native shadow root for stronger isolation; great for design systems. None applies styles globally—use sparingly for global themes or legacy overrides.
@Component({ selector:'x', template:'…', styles:[`:host{display:block}`], encapsulation: ViewEncapsulation.Emulated })
