What Is Angularjs

Angularjs is a structural framework for dynamic web apps. You can use HTML as a template language and extend the HTML syntax to express your application’s components clearly and concisely. Angularjs data binding and dependency injection eliminate much of the code you would otherwise have written. And it all happens in the browser, making it the ideal partner for any server technology. Angularjs is what HTML should have been if designed for applications. In this guide, we will see how to install Angularjs On Linux Server.

Features Of Angularjs

Building a web application is therefore an exercise in what you need to do to make the browser do what you want it to do. Impedance mismatches between dynamic applications and static documents are often resolved in the following ways:

Libraries – A collection of functions that are useful when creating web apps. Your code is in charge and calls the library as needed. For example jQuery.

Framework – A specific implementation of a web application where code fills in the details. The framework is in charge and calls your code when something app-specific is needed. Examples: Durandal, Ember, etc.

Angularjs takes a different approach. By creating new HTML constructs, it tries to minimize the impedance mismatch between document-centric HTML and what your application needs. Angularjs teaches the browser new syntax through constructs called directives. For example:

  • Data binding like {{}}.
  • A DOM control structure for repeating, showing, and hiding DOM fragments. Support for forms and form validation.
  • B. DOM event handling that adds new behavior to DOM elements such as:
  • Group your HTML into reusable components.

How To Install Angularjs On Linux Server

In this guide, we are going to use Ubuntu 20.04 for showing how to install Angularjs.

  • Firstly update and upgrade all the systems to the latest to avoid errors in the next steps. Run the given command to upgrade and update the system components.

# sudo apt-get upgrade && sudo apt-get update -y

  • After that check the node version in your system. Nodejs is a dependency that we require in order to install Angular JS. Node JS is a  cross-platform JavaScript-based runtime environment for the backend. If Nodejs is not installed follow the given link to check how to install Nodejs. Enter the given command to check the Node version.

# node -v

With the output, you can see that Node v18.10.0 is already installed on the system.

  • For the installation of Angularjs Node Package Manager is also required. To install NPM enter the given command.

# sudo apt install npm -y

  • After the node package manager installation, you can run the given command to check its version.

# npm -v

  • Further, as both Nodejs and NPM are installed. We can run the given command to install Angularjs CLI.

# sudo npm install -g @angular/cli

  • Once the installationprocess is finished run the given command to check Angularjs version.

# ng version

How To Install Angularjs

If the ng version commands gives you this output then everything is installed correctly. Now you just have to select a directory where you will be compiling and serving the application. We have now completed all the steps on how to install Angularjs on Linux server.
