What is Directives?
The @Directive decorator is a TypeScript decorator provided by Angular that is used to create custom directives. Directives in Angular are classes decorated with @Directive that defined behavior and logic to be applied to HTML elements in the DOM. These directives can manipulate the appearance, behavior, or structure of elements based on certain conditions or user interactions.
Syntax:
import { Directive } from '@angular/core';
@Directive({
selector: '[appBasicDirective]',
})
export class BasicDirective {
constructor() {}
}
Purpose of the @Directive decorator.
In Angular, Directives are defined as classes that can add new behavior to the elements in the template or modify existing behavior. The `@Directive` decorator in Angular is used to create a directive, which is a class that allows us to attach behavior to elements in the DOM. Directives are a way to extend the functionality of HTML elements and attributes in Angular applications.
