angular-directives

To create reusable Angular directives for DOM behavior, use attribute directives to modify element appearance and structural directives for portals or overlays, leveraging Angular decorators and dependency injection to share patterns like focus or tooltip across components.

Attribute directives in Angular modify element appearance and behavior directly, while structural directives manipulate DOM layout by adding or removing elements, commonly used for managing portals and overlay rendering in component templates.

Use host directives in Angular v20+ to compose multiple behaviors on a single component by applying the directive composition API, allowing you to combine features like tooltip and focus patterns without repeating code.

Yes, you can use Angular signals when building custom directives to manage reactive state, enabling dynamic updates to element appearance or behavior through dependency injection in Angular v20+ projects.

The best way to build tooltip or focus directive patterns in Angular is to create attribute directives with a consistent API, using dependency injection to share the reusable behavior across multiple components.

Yes, implementing host directives requires knowledge of the directive composition API in Angular v20+ to properly compose multiple feature behaviors onto a single component host element.
