The Hidden Power of Angular Directives: Beyond ngIf and ngFor

Cover Picture

Angular directives are a powerful feature that allow developers to extend HTML functionality, handle DOM manipulations, and implement custom behavior without cluttering components. While most Angular developers are familiar with commonly used directives like ngIf and ngFor, there’s a lot more to Angular directives that often go unnoticed. This blog post will dive deep into custom directives, exploring how you can leverage them to handle advanced UI logic and discussing lesser-known use cases of Angular’s built-in directives.

3. Attribute Directives: These modify the behavior or appearance of an element (ngClass, ngStyle, custom attribute directives).

Custom directives, especially attribute directives, are the hidden gems of Angular, offering immense flexibility for handling complex and reusable UI…
