Angular is a JavaScript framework for building web applications. In this tutorial, we will guide you through the process of creating your first Angular 7 application.

Prerequisites

Before getting started, please ensure that you have the following installed on your machine:

• Node.js
• npm (Node Package Manager)
• Angular CLI (Command Line Interface)

Step 1: Setup

1. Install Node.js from the official website: https://nodejs.org
2. Open your terminal or command prompt and verify that Node.js and npm are installed by running the following commands:

node -v
npm -v

3. Install Angular CLI globally by running the following command:

npm install -g @angular/cli

Step 2: Create a New Angular Project

1. Open your terminal or command prompt and navigate to the folder where you want to create your Angular project.

cd angular7-first-app

2. Start the development server by running the following command:

ng serve

3. Open your browser and navigate to http://localhost:4200. You should see the Angular welcome page.

Step 4: Modify the App

1. Open the src/app/app.component.html file in your favorite code editor.
2. Replace the existing HTML code with your own content.

<h1>Welcome to My Angular 7 App!</h1>
<p>This is my first Angular application.</p>

3. Save the file.

Step 5: View the Modified App

1. Go back to your browser and refresh the page. You should see the updated content on the screen.
