All You Need to Know About Using Node.js For Back-end Development | What is Node js Used For?

The server side the back-end development of your product is arguably its most important part. Among all likely back-end development skills to select from, Node.js is one of the basics. It involves the vast majority of modern business fields and real cases. Many smaller business and startups survey their lead and leverage the technology in developing applications.

What is Node.js?

Node.js is an application runtime situation that lets you write server-side requests in JavaScript. Thanks to its exclusive I/O model, it excels at the sort of walkable and real-time circumstances we are progressively difficult of our servers.  It’s also unimportant, efficient, and its ability to use JavaScript on both front-end and back-end development. In this article, I want to deliberate when it is worth using Node.js as backend, and in what bags its strength not be the best idea.

Our NodeJS developers have expertise in scaling the features with Node.js development services.

  • Sataware technologies are leading as a NodeJS service provider in 50+ countries.

  • our software engineers have complete 50+ NodeJS projects.

  • Node.JS Web Application Development 

  • Node.JS Mobile App Development 

  • Node.JS eCommerce, Shopping Cart 

  • We offer an array of node js services

Why is it significant to emerging your project in Node.js?

First of all, using Node.js as a backend for your server technology stretches your team a great boost that originates from using the same linguistic on together the front end and the back-end development. This, income that your side is more well-organized and cross-functional, which, in turn, leads to lower development prices. In addition to that, it’s worth stating that JavaScript is the most prevalent programming language, so your application’s codebase will be calmer to comprehend for more engineers.

Node.js for Back-end Development

You can also recycle and share the code between the frontend and the back end development parts of your application, which hurries up the development process. The Node.js communal is continually increasing – the sum of Stack Overflow requests is progressively increasing, so the data base for the technology is broadly available.

The Aim of Node.js

Its goal is to offer a stress-free and safe way to shape high presentation and climbable network applications in JavaScript. Those goals are achieved thanks to its architecture.

Node.js Highlights

Open Source

Node.js is an open-source agenda MIT certificate that is maintained by a huge community. Its community is attractive much active have donated to add new abilities to Node.js requests.

Simple and Fast

Since Node.js is constructed on Google Chrome’s V8 JavaScript Machine, its libraries are skilled in fast code implementation.


With the benefit of event looping, Node.js can track the single negotiated model. This lets a sole program to switch multiple requirements.


All APIs of Node.js collection is asynchronous, that is, non-blocking. It means a Node.js built server never delays for an API to return data. The server travels to the next API later calling it and an announcement mechanism of Actions of Node.js aids the server to get a response from the earlier API call.

No Buffering

One of the major functionalities of Node.js requests is that it never buffers any data.


Node.js can be simply built and organized on various stages like Windows, MAC, and Linux.

NPM (Node Package Manager)

NPM stands for Node Package Manager which as the term proposes is a package manager for Node.js packages/modules. From Node type 0.6.0. onwards, NPM has been supplementary as defaulting in the node fixing. It protects you from the bother of installing npm openly.

NPM-Node Package Manager

NPM helps in two ways:

  1. Offers and hosts Online sources for node.js packages/modules which can be simply downloaded and used in our developments.
  2. Offers the Command line efficacy to fix various Node.js packages, accomplish Node.js types and dependencies of the packages.

Node.js Modules

The modules in Node.js signifies various functionalities that are pushed up into single or many JS files. These units have a sole context; thus, they not ever interfere or pollute the possibility of other units.

Node.js as backend - Modules

These modules allow the code reusability and improve the ease of custom. Node.js essentially provides three types of modules:

Core Modules: Since Node.js is a very lightweight background, the core units bundle the complete minimum functionalities. These modules usually get loaded when the Node progression starts its implementation. All you need to ensure is import these core modules to use them in your code.

Local Modules: The local components of Node.js are custom modules that are formed locally by operator/developer in the application. These units can contain various functionalities hustled into separate files and folders which can be simply dispersed in the Node.js public using NPM.

Third-Party Modules: You can use the outside or 3rd party modules only by copying them via NPM. These modules are usually developed by other designers and are free to custom. Few of the top external modules are fast, mongoose, react, mocha, gulp, etc.

Where Node.js Can Be Used

Server-Side Web Applications

Node.js with Express.js can also be used to generate classic web applications on the server-side. Though, while probable, this request-response pattern in which Node.js would be carrying around extracted HTML is not the maximum typical use-case. There are opinions to be made for and against this method. 

Node.js - Server-Side Programming

Here are some facts to consider:

  • If your request doesn’t have any CPU intensive calculation, you can figure it in JavaScript top-to-bottom, even down to the folder level if you use JSON storing Object DB like MongoDB. This comforts development expressively.
  • Crawlers obtain a fully-rendered HTML reply, which is far-off more SEO-friendly than, say, a Sole Page Application or a web sockets app execute on top of Node.js.


We’ve discussed Node.js as backend from this concept to training, start with its goals and drives, and finish with its sweet spots and drawbacks. When folks run into complications with Node, it nearly always boils down to the detail that blocking processes are the basis of all evil 99% of Node come as direct purposes.
