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']
})
