angular-directives

You create reusable Angular directives by using attribute, structural, or host directives to encapsulate element behavior and composition without heavy NgModule boilerplate. This delivers a clean API with inputs, outputs, and host metadata.

Attribute directives customize element-level behavior like style or interaction state, while structural directives enable dynamic DOM composition for patterns such as portals and overlays. Both allow you to extend DOM behavior without custom structural constructs.

Host directives in Angular 20+ compose multiple behaviors on a single element and share logic across components. They provide a directive API surface with host metadata, enabling portable DOM behaviors without custom structural constructs.

Yes, Angular structural directives support portals and overlays by enabling dynamic DOM composition. This approach delivers portable DOM behaviors and practical portal patterns without relying on ad-hoc implementation patterns.

No, you do not need heavy NgModule boilerplate to build custom Angular directives. You can design and reuse attribute, structural, and host directives to extend DOM behavior directly without additional module wiring.

The best way to share directive logic across Angular components is using host directives to compose multiple behaviors on a single element. This enables cross-component directive composition and delivers portable, composable DOM behaviors.
