Master Angular Installation Like a Pro and Supercharge Your Web Development Journey!

Published on Jan 05, 2024

Hello and welcome to LSET Tech Bites. In this video, we will learn How to Install Angular in the Windows operating system.

First, let’s understand what Angular is.

The Angular framework was developed by Google in 2010 and is an open-source web application framework. TypeScript is an enhanced, statically typed superset of JavaScript that introduces optional types and other features to make the code more robust and maintainable.

As Angular is based on a component-based architecture, applications can be easily integrated using reusable components. The benefits of this approach include improved project organisation, maintainability, and scalability.

Who Uses Angular?

Many types of developers use Angular, including:

  • Web developers
  • Front-end developers
  • Full-stack developers

Angular’s advantages

Before we start, let’s briefly discuss some key advantages of using Angular for web development.

Encourages Reusability through Component-Based Design

Angular’s architecture, centred around components, inspires developers to craft modular and reusable components seamlessly integrated into extensive applications. This method enhances code organisation, fostering reusability and saving time and effort.

Strong Support for TypeScript

TypeScript, the statically typed superset of JavaScript, is a core part of Angular. TypeScript’s optional types and other features make writing robust and maintainable code easier. This aspect gains particular significance in extensive undertakings.

Emphasis on Modular Design Angular’s focus on modularity ensures that your applications can be effortlessly organised into smaller, more manageable components. This simplifies the process of scaling your projects. And maintain and update them over time.

Built-In Support for Reactive Programming

Angular incorporates built-in support for reactive programming via the RxJS library. This powerful paradigm enables you to handle asynchronous data streams, facilitating handling complex data efficiently flows and user interactions in your applications easier.

Robust Ecosystem and Tools

With Angular, you can access many tools, libraries, and resources to help you make the most of the framework. Angular CLI (Command Line Interface) and the extensive collection of third-party libraries make it easy to build, test, and deploy your applications.

Now, let’s move on to the installation part of the process.

Installing Angular is similar across Windows, macOS, and Linux operating systems. For best results, it is still recommended that you follow the specific instructions for your system.

Begin by installing Node.js and Node Package Manager.

To install Angular, you must ensure that Node.js and npm (Node Package Manager) are installed on your computer. If you still need to install them, please follow the instructions in our guide video on installing Node.js. You can view the video by clicking on the right button on the video or by checking the description box.

The second step is to install Angular CLI globally.

Proceed to install the Angular CLI. Tool. Open the Command Prompt and run the following command to install the Angular CLI globally on your system.

npm install -g @angular/cli

This command installs the most recent stable version of the Angular CLI tool, making it accessible throughout your system.

The third step is to run the Angular CLI commands.

The Angular CLI allows you to manage your Angular projects once installed. Run the following command in the Command Prompt to verify the installation’s success.

Ng version: Using this command, you can view the version of the installed Angular CLI and other relevant information about your environment.

The fourth step is to create an initial workspace for the application.

You will need to create a workspace to create a new Angular application. The workspace contains the configuration files and source code for your Angular projects.

Execute the subsequent command in the Command Prompt to generate a new workspace, replacing my-app with the name of your application:

Upon running this command, you will be asked if you wish to add Angular routing. If you want to install, type Y for Yes; otherwise, type N for No.

After pressing Enter, you will be asked which stylesheet format you want to use. For now, I’m selecting CSS and encouraging Enter to proceed to the next.

Executing this command generates a new directory with the specified name. Configures the necessary files and develops an initial Angular application within the workspace.

The fifth step is to run the Angular application in your browser.

Using the cd command, navigate to the newly created directory where your new Angular application will be tested.

Cd my-app Initiate the development server by executing the following command.

Ng serve Upon running this command, you will receive a prompt. The following message links to Google’s privacy policy, ensuring transparency about how the data will be handled. For this, you can press Yes.

The following command compiles your Angular application and starts a development server. The server runs on port 4200 by default.

Navigate to http://localhost:4200/ using your preferred web browser. Your new Angular application should appear in the browser.

Well, you are done! Your first Angular application has been successfully installed on your Windows computer. Now, you can begin building your projects.
