What is Angular?

Angular is an open source, TypeScript based front end web application framework. It has been released by Google's Angular community.

Angular provides a large collection of tools, APIs, and libraries to build dynamic and interactive single-page applications (SPAs) with ease. It helps maintain an organized and scalable codebase, thanks to its component model and flexible dependency injection system.

Angular Example

In this example, we will write a Hello World! program in Angular. For this, create an Angular application and navigate to src folder. Inside this folder, you will find the app.component.html and app.component.ts files. Copy and paste the following code inside those files:

app.component.ts

 import { Component } from '@angular/core'; import { RouterOutlet } from '@angular/router'; @Component({ selector: 'app-root', standalone: true, imports: [RouterOutlet], templateUrl: './app.component.html', styleUrl: './app.component.css' }) export class AppComponent { title = 'Hello World App'; }

app.component.html

 <h3>{{title}}</h3> <p>Hello World!</p>

On running this application, you will get the following result −

Those web applications that load only one web page and update its content dynamically without reloading are called Single Page Application.

In Angular, decorators are methods more specifically design patterns that are prefixed with @symbol. They provides configuration metadata that specifies how a component, class, or method should be processed and used at runtime. Types of decorators are −

  • Property Decorators
