Duration : 00:02:45
Creating a Component
Components are the building blocks of Angular applications. They encapsulate the logic, UI, and behavior of a specific part of the application.Creating a Component Using the Angular CLI
Angular CLI simplifies component creation by automating the generation of files and boilerplate code.Example
ng generate component my-component
Creating a Component Manually
You can also create a component manually by creating the necessary files and defining the component class, template, and styles.Example
// my-component.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-my-component',
template: '<p>This is my component!</p>',
styleUrls: ['./my-component.component.css']
})
export class MyComponent { }
Specifying a Component's CSS Selector
The selector property in the @Component decorator specifies the custom HTML element where the component will be rendered.Example
@Component({
selector: 'app-my-component',
// ...
})
Defining a Component's Template
The template property in the @Component decorator defines the component's view, including HTML markup and Angular bindings.Example
@Component({
// ...
template: '<p>{{ greeting }}</p>'
})
Declaring a Component's Styles
The styleUrls property in the @Component decorator allows you to specify one or more CSS files for styling the component.Example
@Component({
// ...
styleUrls: ['./my-component.component.css']
})
