Why is node js used?

Today it’s common that building a video streaming app for video conferencing, for example, is often organized with Nuxt.js, Node or Express. Using Node.js for backend web development in 2022 is also a trend. Deploying a Node-based web app or website is the easy part.  So, Why, When & Where to Use Node.js as your backend for a variety of products is a point of discussion.

What is Node JS?

Node. js (Node) is an open-source JavaScript framework built on the Chrome V8 engine. It allows you to write server code for web applications and dynamic web pages, as well as command-line programs.

In fact, Node.js is not just a framework or library, but a runtime programming paradigm that is based on the Chrome V8 JavaScript engine. It includes npm which is the package manager included. The scope of JS does not end there. Recently, this language has often been considered a top contender for server-side programming. And this shift in the web development industry was marked by the emergence of Node.js. You may also come across JavaScript Object Notation, or JSON, which is a lightweight data format that has become a defacto standard for the web.

It’s been successfully used for traditional websites and back-end API services but was designed with real-time, push-based architectures in mind. So, it’s quite a convenient and easy stack to apply for multiple projects.

Besides, despite the general misconception that it’s a backend framework only and is used for building servers, Node. js can be applied on both the frontend and the backend. That’s why there’s much to like about it.

Why Programmers are using Node JS?

Since we’ve already created many award-winning product designs, video explainers and have a direct relation to UX/UI, as well as high-quality product development, it’s nice to explain why we use node js in a variety of projects. We also know how to create successful apps. So, why do programmers prefer using it? Here are some good reasons why:

The speed

The speed is provided by the V8 engine, which was created by Google. It allows you to convert JavaScript code to native code and saves development time when executing a program. Products for building web applications with Node.js can handle significantly more connections.

Cost savings

Node.js development costs a lot less than anything else. Its memory footprint is smaller compared to PHP or Java servers. The server runs in an event-driven loop that saves a huge amount of random access memory (RAM) and in turn software resources.

Real-time development

Developing with Node.js involves a lot of event programming and interacting with a non-blocking server, which is an opportunity to maximize the resources of programmers and save money. The framework, where it is possible to write code in real-time, makes it possible to dynamically create a site.

Preliminary caching option

This eliminates the need to re-execute code when servers call the first module. Caching makes websites load faster and makes the user experience easier. If you ask any programmer, they will say that the main advantage of the framework is the possibility of caching.

Scaling

The technology has services that separate a website or web application into more subtle processes so that different teams can work on them. At the same time, they can be developed with the growth of the product or the increase in user traffic. The V8 engine allows you to develop websites and web applications with subsequent scaling.

You may also find even more reasons here.

Pros and Cons of Node JS

As a robust JavaScript-based technology it has a range of advantages.

By using Node.js as the backend, you automatically get all the benefits of fully functional JavaScript development, including:

• optimal application speed;
• possibility of sharing and reuse;
• a huge number of free tools;
• cross-platform.

Node.js is fast. All this allows you to make the development process as flexible and less time-consuming as possible. As a result, you will receive high-quality and reliable software in the shortest possible time.

Pitfalls of Node JS

Why Node.js might not work for you?

Despite the impressive potential of the project, when considering the possibility of using Node.js for server-side programming, it is worth considering some of its significant drawbacks.

The biggest drawback of Node.js, even now, is its inability to handle heavy CPU-bound tasks. Besides, due to its asynchronous nature, Node.js relies heavily on call-back requests, functions that run after each task in the queue has been completed.

Examples of Where Node.js Should Be Used

To make a long story short: Node. js is well suited for apps types that have a lot of concurrent connections where each request only needs very few CPU cycles because the event loop (with all the other clients) is blocked during the execution of a function. You may create any application instance you want as per this condition.

Conclusion

Node or Node.js is a software platform that turns JavaScript from a highly specialized language into a general-purpose language. Why we use node js? – for many reasons. It may primarily be used for non-blocking, event-driven servers, due to its single-threaded nature and so much more.

Why is node js so popular? It took years for Node.js to become popular and one of the best systems for your client product development & design. At the same time, it remains a young and promising technology that grows and allows more and more options. You may create more products that you imagine both front end and back and with its help. Why use node js for the backend? – Just because it’s easy and flexible.
