Angular Basics

Welcome to the basics of Angular, a popular JavaScript framework for building dynamic web applications. Below, we will explore some fundamental concepts and resources to help you get started with Angular.

What is Angular?

Angular is an open-source web application framework maintained by Google. It is designed to simplify the process of building single-page applications by providing a robust structure and a wide range of functionalities.

Getting Started

Prerequisites

Before diving into Angular, ensure you have the following prerequisites:

• Basic knowledge of HTML, CSS, and JavaScript.
• Node.js and npm installed on your system.
• A code editor like Visual Studio Code or Atom.

Installation

To start using Angular, you need to install the Angular CLI (Command Line Interface). Open your terminal and run the following command:

npm install -g @angular/cli

Once installed, you can create a new Angular project by running:

ng new my-angular-app

Navigate to the newly created project directory:

cd my-angular-app

Building Your First Angular App

Let's create a simple Angular application that displays "Hello, World!" on the screen.

1. Generate a new component:

ng generate component hello-world

2. Open the src/app/hello-world/hello-world.component.html file and replace the content with the following:

<h1>Hello, World!</h1>

3. Now, navigate to the src/app/app.component.html file and add the following code:

<app-hello-world></app-hello-world>

4. Save the changes and run the application:

ng serve

Open your browser and go to http://localhost:4200/. You should see "Hello, World!" displayed on the screen.
