Popularity of Node.JS in mobile app development

Spread the love

Node.JS was first launched in 2009 as a JavaScript (JS) for making server-side apps. Then a cloud solutions provider called Joyent was the first one to use it as an open-source project for the purpose of mobile application development. Since then Node.JS has become extremely popular among various mobile app developers in India and worldwide.

Node.JS is built on the JS runtime environment for developing quicker, lightweight, and highly scalable mobile apps. It utilizes a non-blocking and an event-driven I/O model to make ideal real-time data-bulky real-time apps. Rather than multiple threads, an event loop inside a sole thread is used so that the app can scale to millions of synchronized connections. The post describes the major features and popularity of Node.JS in mobile app development.

  1. Features

(A) Non-Blocking Event Loop

The usual blocking kind feature is used to block successive requests send to the server when the server is busy operating an input/output cycle. Instead of this, an event-loop feature used byNode.JS facilitates request processing together with the input/output cycle. This software model speeds up non-blocking I/O united with event-driven I/O.

(B) Asynchronous Programming

Asynchronous programming makes it feasible to grip the requests by successfully using the restricted clock cycles and memory accessible to its single-threaded structural design. All APIs revealed by Node.JS are asynchronous i.e. asynchronous APIs by means of a callback function.

(C) AJAX and Node.JS

Asynchronous JavaScript and XML (AJAX) is a JS methodology to update parts of a web page without refreshing the web page. The use of Node.JS is to build server-side apps with a full stack of components. AJAX is used to develop client-server web-based apps. Different from this, Node.JS prohibits data swap over from end-user to client-server and vice-versa. While AJAX is only used to update web pages in response to user activity on that page, it doesn’t resolve the dilemma of changes coming from the server.

  1. Node.JS as a popular JS environment

(A) Node official sources reveal that there has been an ample augmentation in contributors to the development of apps via node.js. The applications of Node.JS are in the field of IoT, e-commerce, and payment dispensation. Around 85 nations in the world use Node.JS while developing mobile apps.

Node.JS is straightforward, speedy, lightweight and effectual to build up very responsive mobile apps with the minimum possible memory requirement. So it has become a popular preference when it comes to the building of apps in native script.

(B) Free & Open-Source Toolset

Node.js Package manager (NPM) is one of the biggest libraries of tools and modules that is open-source and available free of cost. This reduces the project development cost to a great extent as additional costs associated with licenses or subscriptions are eliminated. NPM allows developers to set configuration variables, control and install dependencies, find development utilities, and download frameworks required for additional development. These tools are repeatedly reorganized by the vivacious JS community.

(C) Reduced Development Time

Mobile app developers can reuse the same code for frequent operations in the app which reduces the time required to build an app.  Various real-time applications with deep I/O can be developed with Node.JS such as forums, social networks, gaming apps, instant messaging apps, etc.
