Creating a Component in Angular

One of the key features of Angular is its component-based architecture, allowing developers to create reusable and modular UI elements. In this guide, we will walk through the process of creating an Angular component using the Angular CLI and explore key concepts like component class, selector, and input parameters.

To create an angular component follow the following steps:

1. 1 Generate a Component

Use the Angular CLI to generate a new component:

ng generate component user-profile

1.2 Component Class

In the generated component file (user-profile.component.ts), define the component class. This class will contain the component’s logic and behavior.

// user-profile.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-user-profile',
  templateUrl: './user-profile.component.html',
  styleUrls: ['./user-profile.component.css'],
})
export class UserProfileComponent {
  // component properties and methods go here
}

• selector: Specifies the component’s tag name in HTML.
• templateUrl: Points to the external HTML file for the component.
• styleUrls: An array of external CSS files for styling.
