Creating complex architecture of an application

Simple websites can be developed with the basic knowledge of JavaScript. But when it comes to making the complex and structured architecture of a website, the use of React JS becomes mandatory.

React JS allows the developer to incorporates everything in a traditional approach. It ensures every operation by rendering components. All the elements seem easy to keep track of in complex web architecture by writing code in React JS.

Developing interactive applications

Flawless interaction of web applications is the foremost demand of a user. A bunch of front-end technologies is out there, but nobody except for React JS can provide optimal user interaction. React uses a virtual document object module to render components and pass data.

As a result, it can execute the operations faster than other technologies. Easy UI test cases make it highly interactive and prompt in developing applications that work quickly.

What are the use cases of Node JS?

Node JS is not a programming language but operates no less than a robust language. It’s applied to perform all the functionalities of a sophisticated website. Let’s discover the use cases of Node JS:

API server

A web application acts upon the direction of the functions. A back-end developer gives instructions on how a particular app will react. Node JS is the first choice to handle all the back-end activities. It can perform all the server-related operations most exquisitely.

For taking care of HTTP requests, DNS connection, TCP connection, and many more APIs, Node JS plays a significant role. It has the capability to tackle many connections immediately; thus it’s used comprehensively for API servers.

Data management

The database management system is completely handled by Node JS. It’s inevitable to connect the database to the application. From real-time data streaming to data manipulation, everything can be performed through Node JS.

It ensures quick transformation of data and makes the application highly interactive. Besides, it can be used to stream media and gather data from different sources. 


Node JS offers many more micro-services to the web-based application. It’s used to upload files, trace user activity, ensure auto correctness, and so on. For inspecting API gateway, nothing can beat Node JS. It can facilitate the operations of dynamic inputs, buttons, state changing, and many more services at ease.
