Are NodeJs Developers in Great Demand over any other Back-end Technologies?

When developers build a new website, they are going to emphasize front-end as well as back-end development. The front-end code is responsible for creating interfaces employing which the application can interact with users. The back-end code is accountable for interacting with the server to deliver content or data that is showcased to the website's users. 

With this noticeable shift in programming languages and technologies, developers are in the search for a runtime environment that will be able to deliver seamless back-end and front-end interaction and will also aid in building scalable and fast network apps. One of these platforms happens to be Node JS. Mainly because of the ever-growing NPM of Node JS, the developers can execute code quickly. It is not surprising that Node JS consulting happens to be amongst the most profitable career options in technology.

That being said, the popularity gained by Node JS does not translate to fortunes necessarily. On some occasions, shifting to Node JS might prove unproductive in the long run, and it can also be quite disappointing.

In the following paragraphs, we will look at Node JS's usage in different industries and why it is important to hire a Node.js developer. However, before everything else, we will mention a short background of Node JS.

A brief Node JS background

Being launched for the first time by Netscape in the year 2009 and supported by Linux and Mac OS X, Node JS had been created for patching up the Apache HTTP Server limitations, which was the most well-known web server at that time.

During that time, Apache HTTP Server had some drawbacks, including its inability to handle multiple simultaneous connections and difficulties in performing sequential programming.

Node JS was created at the proper time and in the proper place since JavaScript was starting to make headlines with its applications such as Flickr, Gmail, etc. Consequently, Node JS was considered a serious programming language offering a futuristic and innovative website experience. Nevertheless, JavaScript would also boast of having significantly better engines that enabled the users to take advantage of higher speeds and better performance.

There has been a significant improvement in the Chrome V8 engine of Node JS right now. Several innovative tools are offered by this platform for server-side development, thus enhancing the developers' efficiency. As per a survey made by Stackoverflow in the year 2018, Node JS had been voted as the technology which was most extensively used in the “Frameworks, Libraries, and Tools” category.

Some notable entities that have made use of Node JS for customizing their web application environment consist of NASA, Walmart, Uber, LinkedIn, and Paypal.

Will it be a good idea to make use of Node JS in your project?

You will come across various reasons why an increasing number of businesses are shifting to Node JS by ditching their previous back-end setups.

For beginners, being a server-side technology, Node JS will provide your development team with a fantastic boost as it uses the identical front-end and a back-end language. Consequently, it becomes simpler for the development team to function better and execute cross-functional chores easily. For example, in the year 2019, a 35% reduction was reported by PayPal in the average response time following switching to Node JS from Java, with the majority of their pages being served 200ms quicker.

Besides enhanced efficiency, Node JS likewise enables the reuse and sharing of code between the back-end and front-end, thus accelerating the product's development cycle in the long run. Despite this, the Node JS technology stack happens to be free and open-source, which helps to save on the development expenses plus, it comes with an ever-increasing list of tools as well in the NPM registry.
