Hello World in Angular

In this blog, we’ll guide you through the process of setting up a basic Angular application and displaying your first “Hello World” message.

 

Prerequisite:

Node.js and npm: Angular relies on Node.js and npm (Node Package Manager). Ensure it’s on your machine before diving into the world of Angular. Visit https://nodejs.org/ to download and follow the installation instructions.

 

Create Angular app

To create a new Angular project using the Angular CLI (Command Line Interface) with Angular 16, follow these steps:

1.To get started with Angular 16, make sure you have the latest version of Angular CLI installed. Open your terminal and run the following command:

npm install -g @angular/cli@16

2. Once the Angular CLI is installed, you can create a new Angular project with the following command:

ng new YOUR_PROJECT_NAME

Replace YOUR_PROJECT_NAME with the desired name for the project.

3. The Angular CLI will prompt you with some options for project setup. You can choose your preferred options or simply press Enter to accept the default values.

4. Open the app.component.ts file and replace its contents with the code provided below.

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <div>
      <h1>{{ greetingMessage }}</h1>
    </div>
  `,
  styles: []
})
export class AppComponent {
  greetingMessage = 'Hello World in Angular 16';
}

In this example, we’ve created a basic Angular component (AppComponent) with a template that displays a greeting. The template syntax ({{ greetingMessage }}) binds the value of the greetingMessage property to the HTML, dynamically updating the content.

5. Change into the newly created project directory:

cd YOUR_PROJECT_NAME

6. Now, you can seamlessly serve your Angular application locally by executing the following command:

ng serve

This will compile your Angular application and start a development server. You can then open your web browser and navigate to http://localhost:4200/ to see your “Hello World in Angular 16” Angular application in action.

 

Congratulations! You’ve successfully created your first Angular application. Feel free to experiment and explore more features as you continue your Angular journey. Happy coding!
