To build Angular components with signals and OnPush change detection, you structure inputs, outputs, and two-way bindings using signal-based models. This minimizes re-renders and replaces manual state management with computed signals for optimized performance.

Implementing smart and presentational component patterns in Angular separates state management from UI rendering. This approach improves testability, clarifies data flow, and facilitates component reuse across complex user interfaces.

Content projection in Angular uses ng-content to render external content within component templates. Combined with view queries and lifecycle hooks, it manages projected DOM elements and ensures robust UI composition ordering.

You need OnPush change detection with computed signals in Angular when optimizing component performance for complex UIs. This combination ensures components only re-render when signal dependencies change, reducing unnecessary DOM updates.

Angular component lifecycle ordering issues with content projection often stem from querying projected content before initialization. Using appropriate lifecycle hooks and view queries ensures projected content resolves correctly before rendering.
