Top Reasons Why Node.js Is Getting Popular Everyday

Node.js Development

In this digital world, metamorphosis requires breakneck development and mounting solutions. This becomes the cardinal reason for Node.js for getting the glare of publicity in programming languages.

Though the IT industry has such a rapid gait environment where technology becomes outmoded in a snap, the origin can never be taken out. JavaScript is that origin which had started the ball rolling for web development we see today. Node.js can be called as a brood of JavaScript. 

1. The Progenitress- JavaScript

JavaScript is used as the focal language by Node.js to build web development. Since JavaScript is known to many developers and had been used at some point in time, the adaption of Node.js becomes a five-finger. There is always an up to the minute and vigorous framework instigated for developers to set one’s cap at. Node.js has made JavaScript rejigged on the server making this development language to stay for a longer time in the market.


2. It’s Zippy:

Node.js is swayed by Google Chromium V8. The role of V8 is to collate and perpetrate JavaScript into an aborigine machine code resulting in a quick process. There is a single thread cabbalistic event loop in Node.js which pulls off all I/O operations in an asynchronous manner helping in the execution of several tasks in a contemporaneous manner.  


Inside the event loop:


As shown in the figure above, the event loop has 6 phases:


Timely: In this phase, callbacks are executed as per scheduled.
I/O callback: System error callbacks are executed such as Transmission Control Protocol (TCP).
Idle, Prepare: Only used internally
Poll: Here there are two things done by the poll phase. A) executes the scripts for timers whose threshold has elapsed. B) Processing events in the poll queue.
Check: callbacks are invoked here.
Close callbacks: After checking for callbacks in the queue, the event loop wraps up back to the timer to execute the callback.


As per study, an asynchronous task and a callback action are sent to the event loop when an application has to perform I/O operation after which it continues to perform the rest of the program. When the sync is completed the event loop automatically returns to the task at hand.

Thus, reading/writing to file system, network connections, and to the database is executed very fast in Node. It allows developers to build fast and highly scalable network applications that are capable of handling bulk amounts of simultaneous connections having high throughput. One of the best instances of using Node.js is Walmart who undaunted to transpose its out-and-out mobile traffic through the Node.js application on black Friday which is one of the busiest days for shopping. The CPU utilization of their servers didn’t even cross 1% even with 200,000,000 online users.


[3.] It’s Gossamer:


A typical architecture of Node.js is shown in the figure above. Since it has a basic event-driven architecture, every single operation executed is considered as a series of asynchronous callbacks. This is the reason why it runs on a single thread, unlike other web technologies. In other technologies, a new thread is always engendered for every client request. This concocts it to be light-in-weight and forms the nub of Node’s non-blocking I/O feature.


[4.] Solo vocalization for all layers:

Node.js has another windfall which is language re-use. Technologies like Spring or ASP.NET cry out for two languages one on the server side and other on the client side. Antithetically, Node uses the only JavaScript for both client and server sides making it easy for web developers to communicate in a solo language across all layers. Appending it, it can also be re-used repeatedly for future Adding to it, this can be re-used over and over again for future promulgation.


[5.] Extortionate Potential:

As per statista, most used frameworks used as early 2017 was Node.js with 47.1% of respondents. As per a case study, PayPal had uses Node.js which resulted in the escalation of a number of requests per second and reduction in response time by 35%. As per research, LinkedIn, the global networking site, moved from Ruby to Node to handle their mobile traffic resulting in the decrease in the number of servers from 30 to 3 which is almost 90% reduction. The new system was up to 20 times faster. This proof clearly designates Node.js performance capability.


[6.] Can Be Hosted Anywhere

With an expanding germination of Node.js in recent years, several cloud-based hosting providers and web servers are in support of web applications built on Node. Some examples are Google, Amazon AWS, Heroku, Microsoft Azure and many others.


[7.] Modification and maintenance friendly:

Whenever novel specification knocks at your door, built in applications turn out to be less attune and stiff. As they can’t handle the pressure, they start rasping due to stress imposed on those applications. With Node.js, developing new services are easier. It brings a bunch of small applications with itself rather than a single large application. This results in simplicity for modifying and adding new functionalities without diving deep inside the code base.


[8.] Palliate with installation:

Whatever attraction you make saying that the framework is feature-rich, if its installation causes you to invest a lot of time and effort then it defeats the whole purpose. The built-in support for package management using the NPM tool that comes by default with every Node.js installation provides much-needed relief for developers.


[9.] Swift Data Gushing

The reason that node.js development companies are playing om the safer side of the competition is the capacity of Node.js to manage the streams results in an advantage for the input/output bound apps. Being one of the most sturdy applications of Node.js, data streaming facilitates good utilization of time while another process is in motion. As the majority of data that come into the systems are in the form of streams, a lot of time can be saved during this process. Since the ultimate goal is to utilize the time during another operation, Node.js facilitates the same.


[10.] Serves As A Proxy Server


Node.js has an efficacious trait. It can be engaged to surrogate a number of services with distinct response time. For instance, if a server-side application is an indenture for liaising with third party resources, storing images or collecting data additionally, then Node.js can be used as emissary server if an enterprise lacks its professional proxy infrastructure.


[11.] Perfect for Real-Time Application

By reason of event-driven and non-blocking features, Node.js becomes the most pertinent language for applications. As its a brood of JavaScript, it gives you the prerogative to share some code between the client side and server side. Thus Node.js becomes one of the favorite platforms for real-time applications like chatting platforms, online-gaming app, live-tracking, etc. Thus the node.js becomes the secret mantra of web development companies.


[12.] Large & Intellectual Community

There is a cosmic and erudite community for Node.js. They have large-scale code packages and modules that can be put to use for building web applications. Node Package Manager (NPM) is an online archive where open source Node.JS projects are published.

NPM has provisions for packages of re-usable codes which can be assembled as per your project requirements. With around 650,000 reusable codes NPM hosts the world’s largest collection of Node.JS projects.


[13.] Scalability

As discussed earlier, Node.js has an event-driven architecture that facilitates managing requests even waiting for an I/O operation to get completed. Thus it has a non-blocking I/O model. Since it has a single-threaded model with an event loop, it can handle several amounts of traffics with less CPU utilization as mentioned earlier.



Node.js is the talk of the town currently. There is a high possibility that developers can clout to build highly brawny and scalable web applications in the real-time environment. Since it enables data streaming, there is an advantage for the developers to modify or add features in real-time without investing lot of processing time. Moreover, due to its event-driven architecture and non-blocking feature, it becomes like the most loved backend framework.
