Modern Angular components use signal-based input, output, and model APIs for predictable reactivity. You generate standalone components that apply OnPush change detection, host object bindings for ARIA attributes, and inject-based dependency injection to ensure consistent reactive component APIs.

Refactoring class-based inputs to signals involves converting @Input and @Output decorators to signal-based input, output, and model APIs. This shift provides predictable reactivity, enforces OnPush change detection, and removes inconsistent patterns across Angular v20+ projects.

OnPush change detection with host bindings in Angular v20+ is implemented by using signal-based inputs and host object bindings for attributes and events. This combination ensures efficient rendering and automatically satisfies OnPush requirements without manual change detection calls.

Yes, building accessible interactive widgets with Angular signals involves enforcing host object bindings, ARIA attributes, and keyboard interactions. This approach ensures your components meet WCAG/AXE accessibility requirements and pass automated accessibility checks.

Yes, this standalone component pattern fully supports content projection for header and footer templates, alongside lifecycle hooks. It recommends afterNextRender and afterRender patterns to handle rendering efficiently within the OnPush change detection strategy.

Use computed values to derive state reactively from signal inputs and use defer loading to optimize component rendering performance. These patterns are recommended for efficient rendering and managing lifecycle operations within modern Angular standalone components.
