How to write a custom directive to handle copy event in Angular?

The copy command is the most used computer command around the world. Every application demands a futuristic copy command to make the app engaging and smooth for the users. A copy command copies the text or image and stores in a virtual clipboard. The fast-paced technology world wants futuristic copy commands to make the applications trending in the market. Although it is a challenging task for the developers, business owners are focusing on interactive copy features to market their apps efficiently.

The requirement for the copy command rose when I was working on an all-in-one business management platform. It was a necessary feature for UX actions to function smoothly. I was working on Angular; thus, the client wanted to write a custom directive to handle the copy event as copy directives were not available in Angular by default.

Upon intense research, I was able to figure out the right custom directive to be used in Angular. The copy command facilitated smooth UX functioning in the app.

Custom Directive:
import { Directive, Output, EventEmitter, HostListener } from '@angular/core';
@Directive({
selector: '[detectCopyEvent]',
})
export class CopyDetectorDirective  {
@Output() onItemCopied = new EventEmitter();

@HostListener('keydown.control.c') onCtrlC() {
this.onItemCopied.emit();
}
}

Note:- Need to import the class into the relevant module.
Usage:-  <div detectCopyEvent (onItemCopied)=”copyDetector()” ></div>

Technologies or frameworks or tools – Angular, Typescript, Javascript
Angular is an open-source web application framework that is maintained by Google and supported by a community of individuals and corporations. It is commonly used in building single-page applications and dynamic apps with the help of HTML and TypeScript. Angular solves almost all the challenges when creating a web app by combining dependency injection, declarative templates, end-to-end tooling, and integrated best practices. The MVC architecture implementation and enhanced design architecture of Angular make web applications easier and smooth for web app developers.
