Is NodeJS Still Relevant ?

Node.js is extensively used for back-end development and, according to Stack Overflow Research, is a worldwide leader among frameworks. Many experts say whether is node js worth learning 2022 or not depends on your preferences. However, before you answer, you must know that Node js popularity in 2022 is expected to grow even more.

Let us note that there is some confusion regarding the definition of Node.js, some calling it a JavaScipt library, as Wikipedia has it, or a JavaScript framework.

What is Node.js?

In fact, Node.js is neither a library nor a framework, but rather a runtime environment based on Chrome’s V8 JavaScript engine.

What Node.js is used for?

If you wonder what can node js be used for, we provide a brief answer here. Node.js technology was created as an alternative to the client/server model, in which the server reacts only in response to the client request and closes the connection immediately after each response. Node.js establishes a two-way connection and interactive communication between the server and the user’s browser, which allows achieving low latency and high throughput.

What does it all mean?

Well, about a 50% increase in application performance with a simultaneous decrease in response time (PayPal saw a decrease of 35%) and development costs. A good reason for startups to consider Node.js development services, isn’t it? It is actually why Node popularity is so fast-increasing. It looks like not a bad tendency for NodeJs future, right?

The Reasons Why Node.Js Is Popular

Node js in 2022 looks like a massive trend that is going to evolve even more. It offers some undeniable benefits that make it the best choice for software developers. Here we overview a few of them.


It offers a caching ability. In other words, it stores data for some future requests. When the user’s action requires some data, they are involved from the cache. It allows making an application much faster.

Available for many hosting services

Node.js has evolved a lot during recent years, and it has made it available for many hosting service providers.

Node.js is light and fast

This technology uses Google’s V8 JavaScript engine that is built on C++. It makes the app significantly faster and lightweight.


Node.js provides an opportunity to develop applications that can run on both Android and iOS devices.

Node.js Performance Benefits that Still Apply

Here we will consider the five most important Node Js benefits that will make you consider the technology for your next web or app development project.

Modern Architecture and Scalability

Microservices are getting extremely popular today as they allow iterative development and fast scalability of the software. Node.js propels communication among the parts of the applications (APIs of microservices) making it run faster. It gives the opportunity to scale apps without decreasing speed or performance.

Faster Time to Market

Node.js has 700,000 modules on NPM. Using ready-made modules instead of coding mundane things anew cuts the development time dramatically. What’s more, according to the 2018 Node.js Survey, 68% of developers and project managers consider Node.js a factor increasing developer productivity. This contributes to the faster release of products and updates.

Fast Performance

Users’ expectations concerning the loading speed continue to rise. Node.js has been always known to speed up the delivery of back-end services and continues to evolve. One proof is the performance of eBay and AliExpress that Node.js powers.

Open Source Community

Node.js is an open-source technology. It is not only about being free; it is also about the collaboration of highly creative and engaged developers from various corners of the world. For Node.js, there is no rigid money-oriented governance, but a community with an intrinsic motivation to continuously build a product to be proud of.

When You Should Use Node.js

  • Real-time applications. Node.js can power real-time applications (RTA) that process a high volume of short messages and require a minimal delay. For example, Yahoo, LinkedIn, and Uber are all built on Node.js.
  • Data streaming. Considering its asynchronous nature, Node.js is also good for real-time streaming of media, streaming of data from various resources and apps that presuppose multiple file uploads. Netflix running on Node.js is a prominent example here.
  • API servers. Another good application of Node.js is for creating an API server. This is because Node.js allows handling many concurrent connections simultaneously and easily converting JavaSript objects in JSON format.
  • DevOps projects. As mentioned above, Node.js is perfect for writing fast and lightweight pieces of application – microservices – that allow development teams to build, deploy and maintain software at the same time. Continuous development and continuous integration are at the core of DevOps.

A Secret Souce

Here we provided some predictions on the future of Node Js 2022 and for what Node Js is used the most commonly. Now, we also know the key advantages of Node js over Java. Do you ask whether is Node js worth learning? We will just say that Node.js is still a good choice for startups, and NodeJs popularity 2022 is gaining momentum.

However, everything is not necessarily that smooth with Node.js and there are some mistakes in Node.js development developers should learn to avoid. Thus, it is vital to find a reliable Node.js development company that will carry out the project to the best quality standards.

Decoding Nodejs

The main goal of this blog is to explain the “Architecture of Nodejs” and to know how the Nodejs works behind the scenes,

Generally, most of the server-side languages, like PHP, ASP.NET, Ruby, and including Nodejs follows multi-threaded architecture. That means for each client-side request initiates a new thread or even a new process.

In Nodejs, all those requests from the clients are handled in a single-thread using shared resources concurrently as It follows the “Single-Threaded Event Loop Model”.



Event-Loop programming is a flow control in an application-defined by events. The basic principle of Nodejs’s event-driven loop is implementing a central mechanism that hears for events and calls the callback function once an event is turning up.

Nodejs is an event-loop that implements a run-time environment model to achieve non-blocking asynchronous behavior runs on Google Chrome’s V8 engine.
