AngularJS is a popular JavaScript framework for building web applications. In this article, we will learn how to install AngularJS on Ubuntu 20.04.

Prerequisites

Before we begin, make sure that you have a clean installation of Ubuntu 20.04 and a user with sudo privileges. You will also need to have the curl and unzip packages installed.

To check if the curl and unzip packages are installed, run the following commands:

dpkg -s curl
dpkg -s unzip

If the packages are installed, you should see a message saying Status: install ok installed for each package. If either package is not installed, you will need to install it by running the following command:

sudo apt install curl unzip

Installing AngularJS

To install AngularJS, we will first download the latest version of AngularJS from the official website. You can find the latest version of AngularJS at the following URL:

<https://code.angularjs.org/>

To download AngularJS, run the following command:

curl -o angularjs.zip <https://code.angularjs.org/>

This will download the AngularJS zip file to your current directory.

Next, we will extract the contents of the zip file by running the following command:

unzip angularjs.zip

This will extract the AngularJS files to a directory called angularjs.

After the extraction is complete, you can verify that AngularJS is installed correctly by navigating to the angularjs directory and running the following command:

ls

This command should list the files and directories in the angularjs directory, which should include the AngularJS files.

Using AngularJS

Now that AngularJS is installed, you can use it to develop web applications. To use AngularJS in a web application, you will need to include the AngularJS JavaScript file in your HTML file.

To include the AngularJS JavaScript file in your HTML file, you can use the following script tag:

<script src="/path/to/angular.min.js?x76608"></script>

Replace /path/to/angular.min.js with the actual path to the angular.min.js file in the angularjs directory.

After you include the AngularJS JavaScript file in your HTML file, you can use AngularJS to develop your web application. For more information on how to use AngularJS, you can refer to the official documentation at https://angularjs.org/.

Conclusion

In this article, we learned how to install AngularJS on Ubuntu 20.04. We downloaded and extracted the AngularJS files, verified that AngularJS was installed correctly, and included the AngularJS JavaScript file in an HTML file. AngularJS is a powerful JavaScript framework that allows you to develop rich and interactive web applications.
