AngularJS is a Javascript open-source front-end framework that is mainly used to develop Single Page Applications(SPAs). It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML.  It is an open-source project which can be freely used and changed by anyone. It extends HTML attributes with Directives, and data is bound with HTML. 

Features of AngularJS:

  • It facilitates the Model View Controller that helps to connect the model and the view components that manage & responsible for rendering the application data.
  • It provides the concept of Data Binding which is a two-way process, i.e the view layer of the MVC architecture is an exact copy of the model layer, there is no need to write special code to bind data to the HTML controls. 
  • It makes use of the templates, that are passed by the browser into DOM, then DOM becomes the input of the AngularJS compiler and then AngularJS traverses the DOM template for rendering instructions which are called directives.
  • It provides the routing concept that helps to navigate one page to another, without actually refreshing the page. For this, it helps to develop single-page web applications(SPAs).

Example: This example describes the implementation of AngularJS.

HTML




<!DOCTYPE html>
<html>
  
<head>
    <title>AngularJS</title>
    <script src=
    </script>
</head>
  
<body style="text-align:center">
    <h2 style="color:green">GeeksforGeeks</h2>
    <div ng-app="" ng-init="name='GeeksforGeeks'">
        <p>{{ name }} is the portal for geeks.</p>
    </div>
</body>
</html>

Output:

 

Node.js is a cross-platform JavaScript runtime environment. It allows the creation of scalable Web servers without threading and networking tools using JavaScript and a collection of “modules” that handle various core functionalities. It can make console-based and web-based node.js applications.

Features of NodeJS:

  • It implements single-threaded architecture with event looping, making it very scalable. In contrast to typical servers, which create limited threads to process requests, the event mechanism allows the node.js server to reply in a non-blocking manner and makes it more scalable.
  • It provides the scalability that helps to develop scalable software. NodeJS can also handle concurrent requests efficiently. It has a cluster module that manages load balancing for all CPU cores that are active.
  • It facilitates the quick execution of the code by making use of the V8 JavaScript Runtime motor.
  • When data is transmitted in multiple streams, processing them takes a long time. Node.js processes data at a very fast rate. It processes and uploads a file simultaneously, thereby saving a lot of time. 

Example: This example illustrates the basic implementation of NodeJS.

Javascript




<script>
    var company = {
        Name: "GeeksforGeeks",
        Address: "Noida",
        Contact: "+919876543210",
        Email: "abc@geeksforgeeks.org"
    };
  
    // Display the object information
    console.log("Information of variable company:", company);
  
    // Display the type of variable
    console.log("Type of variable company:", typeof company);
</script>

Output:

Information of variable company: {
    Name: 'GeeksforGeeks',
    Address: 'Noida',
    Contact: '+919876543210',
    Email: 'abc@geeksforgeeks.org'
}
Type of variable company: object

Difference between AngularJS and Node.js:

Angular JS

Node.js

It is a structural framework for developing dynamic web apps.

It is a cross-platform run-time environment for applications written in JavaScript language.

It is entirely written in JavaScript.

It is written in C, C++, & JavaScript.

It is used to build single-page client-side applications.

It is used to build fast, scalable server-side and client-side networking applications.

Ideal for developing highly active and interactive web apps.

Ideal for developing small-size projects.

The developer only needs to add the AngularJS file to use it in his application.

The developer needs to install Node.js on his computer system.

Models and views in AngularJS are much simpler than what is found in other JavaScript client-side frameworks.

It uses the event-driven nature of JavaScript to support non-blocking operations and that makes the platform efficient.

It is based on the model-view-controller design pattern and embraces that pattern completely.

It is single-threaded meaning the web requests and processed and run on the same thread.

AngularJS is a Web Framework.

Node.js provides different Web Frameworks like Socket.io, Hapi.js, Meteor.js, Express.js, and Sails.js
