Overview

In today’s world of development, the importance of React as a JavaScript library is well-known. Likewise, its combination with Node.js on the server-side will be accustomed yield a robust combination. during this article, we tend to shall primarily check up on however one will build associate application, creating use of ReactJS on the front-end and Node.js on the backend.

What is ReactJS?

ReactJS could be a JavaScript library that’s principally used for the event of front end-user interfaces. At present, it’s maintained by Facebook, along side variety of individual developers and corporations. the first reason why React is employed is that it will be accustomed fetch chop-chop ever-changing information that additionally mustbe recorded.

So, to merely perceive what React is, allow us to grasp the subsequent –

• it’s one in all the foremost well-liked JavaScript libraries

• not like Angular, that is narrow, React isn’t a framework of any types

• it’s associate ASCII text file project, and as expressed earlier, it absolutely was created by Facebook

• it’s used for the building of user interfaces (UI) on the front-end

• In associate MVC (Model-View-Controller) setup, React contains of the read portion.

One of the first aspects of React is that one will produce elements, that area unit principally custom hypertext mark-up language parts that area unit reusable for a fast and economical build-up of user interfaces.

React may contour however information is keep and handled, creating use of state and props.

Pros and cons of ReactJS.

Just like exploitation the other JavaScript library, React too comes with its own set of benefits and downsides.

Pros –

• React is incredibly straightforward to be told and use. there’s an honest quantity of documentation, tutorials and resources that facilitate in learning. Also, a developer with any previous expertise on JavaScript will simply grasp React and begin operating with it quickly.

• the utilization of React makes it easier for the dynamic development of net applications. exploitation hypertext mark-up language strings to try to to therefore was a fairly complicated task. However, the utilizationcommissioned military officer React has simplified the method. creating use of JavaScript Extension, a syntax that permits hypertext mark-up language quotes and hypertext mark-up language tag syntax to elements, it offers a lot of practicality.

• elements will be reused after you use React. There will be multiple elements and every possesses its logic and controls. Also, each element works to output alittle and reusable piece of hypertext mark-up language code which will be reused where needed. therefore development and maintenance of applications area unit pretty straightforward.

• React additionally ends up in improvement in performance. this is often mostly attributed to the utilization of virtual DOM. DOM, as we know, could be a cross-platform programming API that deals with hypertext mark-up language, ZML, and XHTML. the most important downside two-faced by developers was once the DOM was updated it caught up performance. The React Virtual DOM exists within the memory and happens to be the illustration of the browser’s DOM.

• React additionally boasts of handy tools that create the tasks of developers terribly straightforward. Designed as Chrome and Firefox dev extension, they permit examination of React hierarchies within the virtual DOM.

• React is SEO friendly not like that of ancient JavaScript frameworks. Search engines area unit glorious to face issues with reading JavaScript-heavy applications. However, React overcomes such a haul.

Cons –

• High paced development happens to be each a bonus and a drawback. it’s inexpedient as a result of the chop-chop ever-changing setting makes it troublesome for developers to stay up with the continual set of updates.

• Another major con of React is that the lack of correct documentation. Since React could be a chop-chop change, there’s not a lot of time to create correct documentation.

• React solely takes care of the read a part of the applying development method. Hence, one can want alternative technologies to develop the opposite elements.

• JSX, that is an element of React, employs syntax that uses hypertext mark-up language mixed with JavaScript. However, several within the development community think about this to be a barrier and is kind of complicated once it involves the educational curve.

What is NodeJS?

Node JS

NodeJS, or rather, Node.js is a JavaScript runtime environment that can be used across the platform. It is a complete package that includes everything that is required to execute a program in JavaScript.

The existence of NodeJS happened when the developers of JavaScript extended its functionality from something that only ran on the browser to one that could be run standalone on a machine. NodeJS is presently used to run server-side scripts and brings together web application development around one programming language.

Our assumption

In order to work with React, one will need to have some sort of familiarity with JavaScript. Also, if you happen to come from a different programming language, you have to know concepts such as objects, functions, arrays, and also classes.

Conclusion

React and NodeJS is definitely a powerful combination, and that is exactly what has been demonstrated in this article. It gives you a basic idea about what React and NodeJS is and takes you through a sample application to help you get familiar with the concepts. You can also learn more about connecting a React App with Nodejs and how to become a React developer.
