How to Install and Serve Your First Angular Application: A Step-by-Step Guide

Angular is a powerful front-end development framework that allows developers to build dynamic and responsive web applications. If you are new to Angular, installing and serving your first Angular application may seem daunting. However, with the right guidance, it can be a straightforward process.

Here are the steps to install and serve your first Angular application:

1. Installing Node.js

Before you can install Angular, you need to install Node.js on your computer. Node.js is a JavaScript runtime that enables you to run JavaScript code on the server-side. You can download Node.js from the official website (https://nodejs.org/en/).

2. Install Angular CLI

Once you have Node.js installed, you can install the Angular CLI (Command Line Interface) using the Node Package Manager (NPM). Open your terminal or command prompt and run the following command:

sh
npm install -g @angular/cli

This will install the Angular CLI globally on your system.

3. Creating your first Angular application

After installing the Angular CLI, you can create a new Angular application using the following command:

sh
ng new my-app

This will create a new Angular application in a directory called `my-app`

4. Serving (running) the application

Once the application has been created, you can serve it using the Angular CLI. Navigate to the `my-app` directory using the terminal or command prompt and run the following command:

sh
ng serve

This will compile the application and start a development server. You can view the application by opening a web browser and navigating to `http://localhost:4200`.

Congratulations! You have successfully installed and served your first Angular application. From here, you can begin to explore the capabilities of Angular and build powerful web applications.
