Backend development is complex and affects the overall performance of a solution under development. So to ensure that the system will operate smoothly, it’s essential to choose the most reliable, proven tools. And there are plenty of options to choose from, starting with Python and Java and continuing with PHP, C#, and Node.js. The latter is precisely the focus of this article.

Learn why to choose this technology for backend development and take a look at how dedicated Node.js developers can apply it in different projects. 

So let’s start! 

What Is Node.js?

First of all, it’s a mistake to define Node.js as a separate programming language. It’s an 

open-source JavaScript runtime environment that provides technical specialists with the opportunity to run JavaScript code on the server. The technology perfectly fits web development needs and offers everything needed for the creation of dynamic web pages, command-line applications, and other solutions. 

Reasons to Use Node.js

The popularity of Node.js is high: this JavaScrip runtime environment has the status of the most popular web technology among developers in 2022 (according to Stack Overflow). And for good reasons! 

Let’s take a look at some of them.

It’s easy to learn. 

Why is it important? Because it becomes easier for a company to find qualified specialists to cover their development needs. 

It offers valuable features.

One of them is primitives to synchronize concurrent programming when using Node.js together with JS. It is worth saying that even some really advanced
techs for the backend lack this feature, so it’s a huge benefit. 

It offers opportunities for scalability.  

If there is a need, and in most cases it is, Node.js simplifies scaling of the platform under development, allowing to connect everything on one thread instead of creating new threads for each new connection in the RAM of a server.

It is based on best practices.

Need proof of that? The technology is powered by the JavaScript engine V8 - the one developed by trusted Google specialists and the one having open-source code and a range of good libraries. 

It minimizes the loading time.

Everyone wants their solution to be fast, and Node.js is a good help at this point. It has a caching module that allows the shortening of the loading time in solutions created with this technology in a number of ways. For example, it ensures that the application receives a request and transfers it to in-app memory in the shortest time, in this way contributing to a very satisfying user experience: results requested by a user can be accessed in microseconds.

It can be applied to a variety of projects. 

Node.js has a universal nature: it is good for nearly any project, allowing specialists to create anything: whether it’s some corporate management system, streaming platform, or cross-platform application. 

It perfectly fits the needs of startups.

Offering lots of benefits to developers, such as reusable code, coverage of both front-end and backend development needs, shortened development time, and, consequently, faster time to market, Node. js becomes a perfect solution for startups willing to grow and scale at ease.

Node. js Use Cases 

So now let’s see how Node.js can be applied to create demanded and well-balanced solutions.

Real-time web applications

Whether it’s a streaming service, some collaboration tool, or social media platform, the application of Node.js to such projects often becomes the best choice. Thanks to an event-driven framework and WebSockets, it processes vast amounts of traffic with ease, supporting the essential idea of platforms aiming at real-time information sharing.

IoT

Because Node.js is capable of handling lots of requests at the same time, the technology raises in popularity among those developing ecosystems for connected devices. One more good reason to use it for the above mentioned purposes is the ability of Node.js to store a vast amount of data and be easily integrated with controllers when building digital devices for the IoT ecosystem.

SPA

One of the most popular and demanded solutions today - Single Page Applications - are often created exactly with Node.js. Being able to process I/O intensive workloads and, at the same time, effectively dealing with asynchronous requests, Node.js covers the essentials of SPA development.

The Bottom Line

Now you have a picture of the key reasons for Node.js popularity. But as it is with any other technology, you always have to pay attention to the expertise and experience of professionals applying it to your projects to ensure that the technology is used at its best and will bring you all the above-mentioned benefits.
