When to Use Node.js Development

Before moving on to developing an application, you need to carefully consider and choose a platform for the implementation of the project. In this article, we will talk about Node.js. If you want to know more about this development environment and what applications can be developed there, keep reading this article.

First of all, one point to be made clear is that Node.JS is, by definition, a runtime environment for JavaScript. Due to the features and benefits of this framework, it can be used for batch development as well as Rest API web service or any batch-level tool.

Previously, JavaScript developers could only use the language if they needed to use a web browser, be it Firefox, Chrome, or others. This meant that there was a restriction on the creation of certain types of applications since the applications rendered on the server could not be generated or programmed.

With the advent of Node.JS, a new world of node js development was opened up, where web servers started to appear, built with Express or other libraries based on Node, Rest API.

Why do people love Node.JS?

We can say that Node has a considerable number of features, among which the following stand out:

  • JavaScript development: For development in Node, this is done using the JavaScript programming language, which is currently gaining popularity and development, allowing both front-end and back-end development, paving the way for full-stack professionals.
  • Based on the Chrome V8 engine: This is one of the most advanced JavaScript level engines as it is constantly updated with new features of the ECMAScript 6, 7, and 8 standards. There is also a Node.JS version that uses Microsoft’s native JavaScript Chakra, although most versions and Node projects are based on V8.
  • Non-blocking I/O operations: Node is designed for non-blocking I/O operations, for example, a web server makes one request and waits for a response.
  • Event-Driven (EOP): To understand this feature, let’s think of a data bus where one piece of code operates, reports an event to another instance (at a different point in time), and is received by another piece of code, and performs another action on it. There is a lot of talk at the moment about the term async from the ajax topic. For example, when making requests to an external web service, Rest API, synchronization is a consequence of event orientation, Node.JS handles asynchrony issues very well and is a very good option if we want to talk about the asynchronous codes we want to do for our application.

What is Node.js primarily used for?

Now let’s look at what specific applications use the Node.js environment.

API Development (Application Programming Interface)

The vast majority of web applications require a backend that allows databases to interact with external services, web applications, mobile applications, and others. Thanks to the large community that exists, we can find frameworks that help us develop REST services.

Streaming Applications

Nowadays, every day we use music, video, and TV series streaming services without having to download them to the device that plays them. Nodejs has a built-in module that allows you to sequentially pass large amounts of data in chunks. This functionality eliminates the need to store data temporarily or in the cache to play content.

Applications using the real-time mode

Nodejs is great for handling many I/O operations and can be used to build applications that implement real-time behavior in their services. A classic example of real-time applications is the chat or video conferencing room and chatbots. These applications are made possible by the Nodejs Events API and WebSockets features. Most used frameworks:

  • Socket.io
  • Socket cluster
  • Feather.js


The microservices approach to architecture has become very popular and is based on the creation of small services that are autonomous but interact with each other. Given the lightweight nature of Nodejs, it’s easy to make solutions scalable and ideal for implementing microservices. Here are some libraries focused on microservices:

  • Micro.js
  • Molecular.io

It’s safe to say that Node.js allows us to develop a huge number of cool and unique applications that will help us achieve our goals and follow a strategy.
