NodeJS: A Comprehensive Guide

JavaScript is undoubtedly one of the most popular programming languages ??today and for all good reasons. It can be easily run in your browser, on a server, on your desktop, or even on your phone as an app. There are multiple frameworks, platforms, and technologies made available using the power of JavaScript. One of the most popular and easiest ways to write JavaScript code to create a web app or software is to use NodeJS development.

In this blog, we will share more details on Node.js to help you understand this runtime environment better.

What is NodeJS?

  • NodeJS is an open source, cross platform JavaScript library and runtime environment that is used for running web applications outside the customer's browser.
  • It is a lightweight framework used to build server side web applications.
  • It extends the JavaScript APIs to provide common server side functionalities.
  • It is generally used for large scale application development, especially for video streaming sites, single page applications, and other similar web applications.
  • NodeJS development companies hold expertise in using event based, non-blocking I/O model of Node.js. This model makes Node.Js development a suitable choice for data intensive real time application development

 

Key Characteristics:

Open source:

  • Node.js is an open source framework that is supported by a large community.
  • Its community is quite active and has helped adding new features to Node.js applications.


Simple and fast:

  • Since Node.js is based on Google Chrome's V8 JavaScript engine, its libraries are capable of executing code quickly.

 

Asynchronous:

  • All Node.js libraries are asynchronous. It means that Node.js based servers never wait for an API to return the response and move on to the next API.

 

High scalability:

  • Due to the event mechanism, Node.js is highly scalable and helps the server in a non-blocking response.

 

Cross platform:

  • Node.js can be easily built and deployed on various platforms such as Windows, MAC, and Linux.

 

Ideal for real time applications:

  • The language has extraordinary characteristics for creating real time applications such as chat and game applications.
  • It is also ideal for programs that require an event based server.
  • One can always hire NodeJS developers to help out in building the applications.

 

High performance:

  • Single threaded JavaScript runtime provides integrated network applications.
  • Based on the Google Chrome V8 runtime and encoded in C ++, Node.js is specially designed for various operating systems.

 

Why Node.js?

No buffering:

  • Node.js dramatically reduces processing time when loading audio and video files.
  • Node.js applications never buffer data and just generate data in chunks.

 

Single-threaded:

  • Node.js uses a single threaded model with an event loop.
  • As a result, it can handle a much higher number of requests than traditional servers like the Apache HTTP server.

 

Highly scalable:

  • Node.js server responds without blocking, making it highly scalable unlike traditional servers, which create limited threads to handle requests.

 

These reasons justify the popularity of NodeJS development and why it is adopted by a large number of organizations and companies.

If you have a project to build a web app, it is very profitable to hire NodeJS developers for application development. We, Orange Genesis, offer a resource hiring model. You can hire NodeJs developers at affordable rates. Contact us to discuss more in detail.
