What is Angular?

Angular is a frontend, TypeScript-based framework developed and maintained by the Google team. It helps build and develop Single-Page Applications (SPAs). Now, the first question that might come to your mind is what is an SPA?

What is an SPA?

SPA stands for Single-Page Application, which is a web application that updates content without refreshing the main page. If you navigate from one section to another, such as from Home to Contact, or Contact to Blogs, the main page does not reload or refresh. This behavior is what defines an SPA.

Why Angular is Important?

As discussed earlier, Angular is a frontend framework based on the TypeScript language. TypeScript is a superset of JavaScript that allows us to declare typed variables, unlike JavaScript.

Example:

// Using TypeScript
 name: string = '';
 // Using JavaScript
 let name = '';

In TypeScript, a variable declared with the string type cannot accept any value other than a string, whereas in JavaScript, a variable declared with the let keyword can accept any type of value, such as string, number, boolean, etc.

Since Angular is based on TypeScript, it provides better security, catches errors at compile time, and is well-suited for complex applications such as those in the banking and healthcare domains.

Features of Angular

Here are a few important features that make Angular highly in demand in the current market:

  1. Two-way data binding
  2. Reactive forms with robust validation support
  3. Its own built-in dependency injection
  4. A routing module for managing navigation throughout the application
  5. Support for building single-page applications
  6. Lazy-loading techniques
  7. Directives to manage DOM element behavior
  8. Signals for better state management in Zoneless applications
  9. Support for RxJS and NgRx libraries

Chapter 1: Getting Started with Angular

1. Prerequisites

Before getting started with Angular, you should have a basic understanding of the following

  1. HTML
  2. CSS
  3. TypeScript

2. Setup and Installation

  1. Install a supported IDE: VS Code is the recommended choice.
  2. Install Node.js (LTS version from https://nodejs.org/en/download).

3. Verify Node Installation

Verify the Node.js installation. First, open Command Prompt (cmd) or Node.js Command Prompt and type node -v, then press Enter. It will display a message similar to:

C:\Users\vkumar>node -v
v16.20.2

This verifies that Node.js is installed successfully with the respective version. The version may vary based on project requirements.

Once you are done with the installation of the above tools and software, let’s proceed with the further setup.

4. Steps to Create Your First Angular Application

Here are the easiest steps to create your first Angular application:

  1. Create one folder (e.g., AngularApplication) in your preferred location, such as Desktop, Documents, D drive, etc.
  2. Open your preferred IDE (such as VS Code) and open your created folder in it (go to File -> Open Folder -> select folder and open).
  3. Now you have two options to create your first Angular application.
  4. Open either Node.js Command Prompt or the terminal in VS Code IDE.

5. Install the Angular CLI

CLI stands for Command Line Interface, which is used to handle your entire Angular application via commands such as creating components, modules, pipes, directives, services, etc. Here is the command to install Angular CLI:
npm install @angular/cli
or
npm install @angular/cli@version

Where the version can be anything based on your requirements. Now let’s install the CLI globally:

npm install -g @angular/cli

Here, -g refers to global installation, which means it will be installed globally. Once you are done with the CLI installation, it’s time to create your first Angular application. Run the command below in your terminal:

ng new application_name

Here, application_name is the name of your Angular application, which can be anything. It varies from project to project and developer to developer. It might ask a few questions; go with the default options.

Now you are at the final stage of creating your first Angular application. Navigate to your project or application directory using:

cd application_name

and run the following command:

ng serve

Once you run the above command, the application will start on the default port 4200. Go to any browser (e.g., Chrome), enter http://localhost:4200, and press Enter.

Congratulations, you have created your first Angular application.

Honestly, being a full-stack developer, I would like to share my own experience with you. Doing all this setup and creating the first project took a lot of time and patience. No one will guide you this deeply, the way I am explaining every step. Contact us; we will guide you via a one-to-one meeting step by step in case you face any issues. Till then, keep learning and keep growing. Continue to the next Chapter.
