Rise of Node.js

what's Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside the window.Node.js allows developers to use JavaScript to write command line tools and run server-side scripts to create dynamic web page content before the page is submitted to the user’s web browser for server-side scripting.

As a result, Node.js is a “JavaScript everywhere” paradigm that unifies the development of web applications around a common programming language, rather than separate server- and client-side script languages.

In plain words, Node.js shines through the use of push technology in real-time web applications over websockets. But what is so special about it?

It is unique because it has transformed an age-old standard based on a stateless web & request-response. With Node.js, we have finally entered the world of real-time web applications with two-way connections, where both server and client can start communication by openly exchanging the data. This used to be completely different earlier, when only the client had permission to initiate the communication

Node.js was first unveiled by Ryan Dahl at the annual European JSConf in 2009. Node.js was initially funded by hosting solutions and cloud storage provider Joyent as an open-source project.This business has also invested in many innovations, such as the Ruby on Rails platform, and has also provided LinkedIn and Twitter with hosting services.

Moreover, LinkedIn also became the first company to use Node.js technology for the backend development of its mobile application. Later on, many other companies like Netflix, Walmart, eBay, Uber, and many more adopted Node.js.

Rise of Node.js through stats

Not only is Node.js’ rise an ordinary claim, it’s well backed up by the stats. The graph below shows Node.js’ dominance in the IT world as of 2019.You should note that the chart above indicates and contrasts the growth and not the total number of workers.With the maximum number of work offers, Java also rules against it. The graph explicitly shows us that, relative to all other technologies, the growth rate of Node.js is the highest. Now many of you would argue that for all the innovations in their initial years, this trend will be the same. So, how could this be a big deal? Well, you got the first stuff right that in the beginning, any new technology gets a boost.

In addition, there are plenty of creative startups that would consider having a go at a relatively new technology. The thing that makes Node.js different from any other technology, though, is that many existing businesses have already implemented Node.js. This phenomenon is quite rare and it’s what makes Node.js different from all the other technologies.

How Node.js architecture works?

Node JS is built on an architecture that is event-driven. The two characteristics that make the output of the Node notable are its non-blocking nature for each I/O, along with the fact that it is asynchronous.

These features also increase its scalability for the creation of large-scale enterprise web applications consisting of large volumes (input/output) of transaction activities. Node also scales mobile applications and games seamlessly, which requires real-time collaboration, in addition to business solutions.

Let’s take a restaurant’s example to grasp Node.jS’s non-blocking and asynchronous existence. There are several tables in a restaurant where individuals sit and order. The waiter writes it down after the order is put and tells the chef to prepare the order.

A waiter takes several orders at once while the first order is still being prepared by the chef. Here, the waiter does not have to wait until the chef finishes making the first order for other tables to be served. It is also very close to working with Node.jS. Like a waiter, the thread assigned to handle a request can handle several requests at a time. To understand synchronous and blocking existence, we can use the same restaurant example. In this, the waiter takes the order from one table and then waits until it is ready in the kitchen. The waiter could not take any other items during the preparation of the meal.

In such cases, for each submission, you’d need one thread. This means that you can run out of threads if the number of requests is enormous.

These situations illustrate the counter-productivity of the synchronous and blocking nature, as several threads are made inoperative, you will have to wait because of those additional requests. This is exactly how synchronous and blocking technologies such as ASP.net and Ruby on Rails operate.

How Node.js architecture works?

Node.jS is based on a V8 JavaScript engine from Chrome. It’s an asynchronous JavaScript runtime driven by events. Using the non-blocking/event-callback method, it provides a single-threaded event-io model that allows all activities that run in parallel to be coordinated.

Moreover, it doesn’t require a large memory footprint to support multiple connections. Application of Node.js goes beyond than just web application development. It can be also used for:

Frontends

Backend and servers

API development

Microservices

Automation and scripting
