Your Complete Comparison Guide to Node JS and Angular JS 11 March, 2021   

There’s no doubt that JavaScript is the modern-day language of the web and tech worlds, and you can literally find it everywhere from the apps we use, the services we rely on, and the games we play. Online, there are so many websites that are built using this framework as a foundation.

From these foundations, other frameworks like NodeJS and AngularJS have risen up and today stand tall, but if you’ve clicked on this post, like so many others, you’re probably wondering what the difference between the two is.

Let’s get straight down into it and find out.

What is NodeJS?

Let’s start with the basics.

NodeJS is known as a ‘cross-platform’ runtime library and JavaScript environment that allows JavaScript applications to run outside of the traditional browser setting. Basically, if you want to run Java apps outside a web browser, say an app or a game like Minecraft, you’re going to need NodeJS.

All NodeJS applications are written in the JavaScript language, are both free and open-

sourced, so you can edit and adjust the framework however you want, ensuring your

applications are fit for purpose and you can run on both Linux and Windows systems.

What a lot of people love about NodeJS is the fact that it comes with such a vast library of

modules that you can use during the web development process to simplify and

uncomplicate what you’re doing.

What many developers are also loving at the moment is the fact that Node.jsteam now exists, which means the NodeJS can easily be used to create and develop mobile-ready applications, which is opening a whole new door of possibilities for JavaScript developers.

For clarity, the key features of NodeJS you’re going to want to think about are;

  • NodeJS is open-sourced and completely free. Anyone can download and use it as they please.

  • Allowing for non-blocking operations, you can make some really great web applications with this framework.

  • The super-powerful integrated APIs means you can connect to all kinds of servers with ease, including HTTP, DNS, TCP, and many more.

  • The scalability options of NodeJS are just insane, both vertically and horizontally, which means it can infinitely improve the performance of your application.

  • The built-in Jasmine system is a unit testing protocol that allows developers and coders to easily test the code they’re writing, only streamlining your ability to create products that work amazingly.

What is AngularJS?

Unlike NodeJS, AngularJS is all about staying within the web browser and provides a very helpful framework and structure that allows you to create really fancy, high-performing web-based apps.

What’s special about AngularJS is the fact that you can still use HTML languages as a template and can even allow HTML to syntax clearly. Lots of potential there. However, it’s still very much classed as a standalone JavaScript framework that has one very powerful goal.

To keep things simple.

This is why the framework specializes in single-page apps and supports the traditional MVC programming structure.

Just we did in the previous section, the key features that can help you define what AngularJS is are as follows;

  • The framework works in a fantastically integrated way with the effortless MVC framework, making it incredibly easier for you to build client-side applications that get the job done.

  • AngularJS is super easy to use and effortless for someone to pick up, especially when compared with other more complex JavaScript frameworks out there.

  • In addition to the MVC framework compatibility, Angular is accessible through the MVW architecture, which is essential when it comes to modeling, remodeling, and manipulating DOM. This works for both the data itself and the behavior of the output.

  • While these are all technical features, Angular works very well with plain and straightforward JavaScript functions, meaning there’s another reason why this framework is so easy to work with.

The Key Differences Between NodeJS and AngularJS

Okay, so let’s dive into this and make everything a bit more detailed. After all, there are some similarities, such as both NodeJS and AngularJS being the top, most used frameworks in 2017 and 2018, with NodeJS being used 47.1%, and AngularJS being 44.3%.

However, for this next section, we’re going to really focus on the core differences between the two JavaScript components.

For example, NodeJS is the cross-platform, open-sourced environment for JavaScript applications, whereas AngularJS is still open-sourced, but Google officially maintains it.

Sarah Farrow, a web developer at Originwritings and Coursework Writer, explains some of the other points you’ll want to consider.

“There are other key differences like NodeJS environments need to be downloaded and installed on your PC if you want to use them, whereas AngularJS can simply be added to a JavaScript file to work, just like other JavaScript files you’re probably using.”

She then goes on to say,

“Perhaps interestingly, NodeJS is actually classed as a platform that is built on the foundations of the Google V8 JavaScript engine, whereas Angular (although maintained by Google) actually just follows the mainstream syntax of modern-day JavaScript.”

I mentioned already that AngularJS is written in the JavaScript language, but it is actually written in a way that’s different from other similar frameworks, such as JQuery. NodeJS, on the other hand, is written in languages like C, C++ and mixed with JavaScript.

Getting into the technical side of things, you’ll find that NodeJS supports typical non-blocking I/O API. This includes other script types that include;

  • TypeScript

  • Ruby

  • CoffeeScript

  • Dart, and many more.

While AngularJS is compatible with the same frameworks and modules, it also allows for the addon of HTML syntax. However, both frameworks are capable of handling and supporting functional, object-orientated, and event-driven programming paradigms.

Finally, perhaps the most key difference of them all, NodeJS is designed to work alongside other JavaScript frameworks, including some of the likes as Express.js, Sail.js, and partial.js. Alternatively, AngularJS is actually a framework that can standalone with itself.

Which is Best for You?

Perhaps onto the real reason why you’re here, and that’s because you’re trying to decide which JavaScript component is best for you and whatever project you’re working on. You know the differences between the two, but which one is going to allow your project to shine?

“Well, know that both NodeJS and AngularJS are used for creating web applications, and while they both work and operate differently, they are both used for very similar functions. The main way you’re going to be able to distinguish the two is this, and I’m going to make this easy for you,” explains Terri Marie, a business writer at Academicbrits and Phdkingdom.

NodeJS is best for building powerful server-side applications. AngularJS is best for single-page, client-side, web-based applications. That’s the main difference. Both solutions are powerful and are commonly used in many applications around the world, so this is the very best way you’re going to determine between the two.


While similar in a lot of ways, there are some apparent differences between NodeJS and AngularJS frameworks, and hopefully this guide has explained everything you need to know to help you decide which framework is best for you and which one you’re going to use moving forward on your next project.

All you need to do to figure out which approach to take is to decide what kind of application requirement you’re working with and which one best suits you. However, at the end of the day, there’s no denying that both frameworks are fantastic choices as they both excel and doing what they do, and it’s very exciting to see what they’re going to be capable of doing over the upcoming years.

However, there may be other comparisons you want to make first, just to make sure you’re choosing the right framework. Other notable frameworks may include Knockout, JQuery, React, and Bootstrap, but that’s entirely up to you.
