Why Learn Node JS for Web App Development?

April 28, 2022

Web app development is no longer what it used to be. Time has changed, and so is the approach. A good web app requires strong backing from progressive, powerful technologies designed for that particular operation, just like JavaScript – The inseparable part of the web app development process.

We all know that JavaScript tops the most used front-end and back-end technologies. But what people don’t know is that JavaScript is also a crown holder of client-side programming languages. It has revolutionized web apps and the cross-platform app development sphere.

Node.js, React.js, and Angular.js all fall under the same roof as the most successful JS technologies, but as an experienced Node js development company, we’ve observed Node.js holding the prime positioning in server-side programming and plays a crucial role in developing web apps.

Owning massive respect due to its feature-packed status, Node.js is used by more than 49.9% of JavaScript programmers – Reported by Statista. 

Sounds interesting? Let’s have a profound understanding of Node.js and how is it perfect for website and application development.

What is Node.js?

Emerged in 2009 and quoted as the ‘most exciting single piece of technology in the JavaScript universe’, Node.js is neither a framework nor a library but an open-source, cross-platform runtime environment for JavaScript to build server-side and client-side web apps.

How Node.js is best to create fast and scalable web applications

Let’s have a closer look at Node.js advantages for web application creation: –

V8 Engine

Node’s architecture is designed and built on Google’s high-performance V8 engine. Though the engine was initially conceptualized for Chrome, the Node.js team leveraged it for their environment’s purposes. This engine transforms specialized JavaScript into general code based on C++.

V8 engine analysis the JavaScript that’s only understood by browsers and translates it into a language that’s easily processable by machines and servers. What makes the V8 one of the best engines in the industry is its constant updates. Team Google actively works on it to keep its performance intact and speed improved with every new version released.

Scalable Web Application Construction

Scalability is crucial, and Node.js was built to meet this scenario. Node.js has a cluster module that balances every running CPU core load. It can process multiple nodes simultaneously while keeping a serene communication flow. It further increases personalization and decreases workload through its horizontal partitioning feature, where an app can be split into several instances to present its variety of versions to users based on their age, interests, language, location, etc. Most important, Node’s non-blocking input/output model uses an event loop request-processing system for high speed, letting apps process thousands of requests without a jitter. When scalability is the concern, no web backend development solution can surpass Node.js.

Corresponds well with JavaScript

One of the most evident reasons that make Node.js suitable for web app development is its coherence with JavaScript. Being from the same programming family, Node’s syntax, structural principles, and functionality are similar to general JavaScript. If you have a team of JavaScript engineers, it will be easier for them to learn JS-based Node, an entirely new language. Moreover, the front-end and back-end codebase will be similar, easy to grasp, and maintain because everything is JS-based.

Powerful Data Processing

A backend development language or run time environment must be able to process requests seamlessly. Node.js is efficient in data processing through its data handling tool. Here’s how:-

  • Other back-end technologies use synchronous processing by placing all requests in a single line. In contrast, Node.js follows an asynchronous structure in which requests are processed together without block delays. Node helped SuperBowl (Web hosting company) handle 10,000 requests per second with absolutely no downtime.
  • Unlike other backend technologies that follow a linear software development approach, Node.js follows the event-based programming approach. Where a linear tool executes algorithms in a series regardless of users’ actions, Node’s event-based model enables the app to react to the users’ inputs. There are no unnecessary background operations, and only quick reactions will be seen as per visitors’ needs.

Reduces loading time by Quick Caching

Node.js facilitates load balancing over multiple CPU cores. It simplifies tasks with a module called caching. Every time your first module is asked, you are logged in. So users can browse quickly without waiting too long. eBay benefited quickly from NodeJS by including it on their IT stack, as they wanted it to be as effective as possible with live communication. Node.js minimizes the load speed by leveraging built-in API for developing HTTP and DNS servers and JSON, a data format, for smooth data exchange between client and web server.

Microservices development in a fast environment

There is another reason why Node.js became so popular so quickly. It is ideal for developing microservices (splitting monolithic functionality into dozens or hundreds of smaller services).

Microservices must communicate quickly, and Node.js is one of the fastest tools on the market. Node.js’ non-blocking algorithms are one of its main advantages for software development.

Multiple requests can be processed by Node.js simultaneously without waiting for the first one to finish. The messages can be sent to dozens of microservices, and the messages will be received and answered simultaneously.

Enhanced functionality from Node Package Manager

When you download the Node runtime environment, you get access to NPM (Node Package Manager). Some people in communities also call it a node.js package marketplace where you can find ready-to-use code libraries and additional functionality. Official statistics show that more than 100,000 new packages are added weekly. There are hundreds of Node.js modules, frameworks, and packages shared by top developers for free.

Vibrant community

The Node.js community is incredibly active on GitHubStackOverflowand Reddit. Developers are even allowed to create dedicated group chats on Slack and Gitter that everyone can join. The community reviews each other’s code, shares reusable fragments, suggests frameworks, and answers all Node-related questions. Node’s community is a great place for growth, learning, and innovation.

Big corporations vouch for Node.js

Joyent, the company that supported Node.js in its initial days, developed the Node.js Foundation, which has become a part of the JS Foundation. All companies are welcome to join and help the tool evolve. Presently, foundation members include Microsoft, PayPal, Trello, Medium, IBM, and others.

It is also one of the distinguishing factors of Node.js application development that it is not just limited to community resources but has a reach to the world’s leading corporate resources.

Top Node.js frameworks for client and web servers development

Top node js frameworks

As per a Node.js web survey report, Node.js is considered the best to increase a JS developer’s productivity through its 68% faster code execution, slacking off development costs, and enhancing app performance to a great extent. It is a result of the successful usage of Node.js frameworks.

Top companies that incorporated Node.js

Companies incorporate nodejs

As stated above, Node.js is one common thing among the world’s most popular brands’ mobile apps. Let’s understand how these brands utilized the features of Node.js to beat their challenges: –


Uber is the first of three companies that utilized Node.js in the complete production stage. It leveraged Node for high-speed and scalable application development in its cross-platform tech solution to manage a massive number of user requests. Node.js helped Uber match multiple riders to their drivers in seconds.


Netflix needed a reliable solution to handle multiple requests simultaneously. Because of over a billion hours of weekly data streaming, their developers used Node.js for efficient data circulation. Node also helped Netflix build a fast-loading SPA, improving its start-up time from 40 minutes to 60 seconds.


LinkedIn needed a powerful technology to support their enormous 59% of traffic logging in from their mobile app. Node.js helped LinkedIn reduce servers from 30 to 3, lower memory head, draw their focus from troubleshooting to app development and boost the holistic performance by 20 times in several cases.
