Prasanna Gopinath

As you might know, JavaScript has been the most popular programming language for years now. This common software development technology was initially employed for front-end only, but recently it has become the main tool for back-end as well. It is also used for cross-platform mobile app development.

Node.Js is a buzzword in the development sphere and means a server-side platform. It’s often referred to as a programming language, but it is not. In fact, it’s not even a framework or a library. Node.JS is a cross-platform runtime environment. It’s built on V8, a high-performance open-source JavaScript engine.

Node applies event-driven, non-blocking IO paradigm. NPM or Node Package Manager is currently the most extensive software registry in the world. It was introduced back in 2009 and was immediately seen as an exciting piece of software.

Node.JS provides a more natural development process and more efficient performance. It is mostly preferred for API development due to its ability to scale smoothly while handling multiple requests. It makes Node. Js development a great choice if you want to build a streaming web app with multiple concurrent connections. So without further ado, let’s consider the most significant advantages of Node.Js.

Mobile Friendly

We are living in a mobile age, so mobile-friendliness is crucial for many industries today. Node.Js has impressive adaptability and efficiency and gives the possibility to handle the growing volume of mobile traffic. Furthermore, it helps prevent the server from crashing and allows creating responsive web sites faster than ever.


A core benefit for startups is Node. Js’ scalability. It perfectly fits most microservice architectures, ensuring their better flexibility. Node Js beaks the app logic in small modules allowing developers to add more modules to existing ones easily.

Node. Js is widely preferred now for developing microservice solutions. Walmart is an excellent example of an architectural approach. Moreover, Node applications support both vertical and horizontal scaling.

Faster Development Process

Node.Js is a perfect solution for startups due to the ability of a fast development process and shorter time needed to make a finished product hit a market. Node.Js is very lightweight and has plenty of tools to boost development speed. The NPM registry offers many solutions and libraries that help create value without excessive effort. It provides reusable temples as well. It reduces the app size and the number of bugs. All it leads to a shorter time-to-market.

Community Support

The Node.Js foundation was created back in 2015. It was established to handle the development and production of the Node. Js project. Some of its members are the industry leaders working for the giants such as IBM and Microsoft.

The Node.Js community currently consists of thousands of contributors. Node.Js is used by more than three hundred startups and established companies. It makes Node.Js a time-proof tool, which can’t be neglected.

Since we can’t list all of Node.Js benefits in one article, we will consider only the most actual use cases displaying Node Js’ advantages.

Real-Time Applications

Collaborative applications like Google Docs, messaging apps, and online gaming are great examples of real-time applications. All of them can significantly benefit from Node.Js architecture. Node.Js brings a solution for the low-latency, which is crucial for real-time apps to make them work more efficiently. It could handle multiple requests and makes the data sync between clients and the server happen much faster.


This leading company operates a global online payment system. It has replaced traditional paper payment methods. PayPal has recently shifted away from obsolete architecture to adopt an open-source model. They have moved to JavaScript and Node.js, in particular. It has given teams the ability to modularize the structure and deliver faster.

App Customisation

If you use Node.Js as your back-end technology, it allows modifying an app much easier. It could be a significant advantage, and it’s an absolute must for web apps that gain traction. Each module could be built with a different set of tools. It makes Node.Js very adaptive to changes. The modular approach is quick and easy to customize.


Groupon is among the biggest e-Commerce industries. It has now replaced Ruby on Rails, Java and PHP stacks with a combination of Node.Js, Java, and Ruby for back-end services. What drove this decision was the low learning curve, the ability to use elements of code over and over again, and better scaling.


Another specific example is Netflix. To improve and keep pace with business, they have decided to switch their backend from Java to Node.Js. It’s language consistency also had a crucial impact on that decision, as their frontend already ran on JavaScript.

Dow Jones

Dow Jones was among the first companies to implement Node.Js. They have been using it since 2011. Ever since then, Node.Js delivered all the expectations, providing efficient performance, and boosting the development time significantly.

Node.JS Development Is What Your Web App Needs

Today, many companies, including NASA use Node. They already know that it’s currently the best way to improve efficiency and performance. Node.Js provides many opportunities for developers.
