Node.js vs Reactjs: Which One You Should Opt For?

Node.js and React.js

Last Updated on July 4, 2024 by Team Experts

Node.js and React.js both are the broadly used subsets of JavaScript and are technically different. JavaScript has become the most preferred choice for developers.

There are various frameworks of JavaScript and to know which one is better we will compare two of the frameworks, Node.js and React.js.

The main difference is Node.js is a back-end framework and React.js is used for developing user interfaces. Both frameworks are quite popular and have their advantages and disadvantages.

The frameworks serve different purposes in the web development world and are not substitutable. In this article, we have tried to compare Node.js and React.js based on performance, knowledge curve, community, and microservices support.

Node.js vs React.js:


React.js is an open-source JavaScript library that can be used with the browser. It is a front-end framework used by React.js development companies to develop user interfaces for websites and apps in an organized way.

The main advantage of this framework is that it allows the development of an active library with high performance.

When to use?

It is developed by a Facebook team and is used for everything from content-based websites to mobile apps. Some apps that are made using React.js are Facebook and Instagram. The library of React.js helps the Netflix team to improve runtime performance, modularity, and rapidity.

Features of React.js:

Simple support: This library re-utilizes framework parts and comprehends any issues associated with React refreshes.

Execution: React is utilizing Virtual DOM (document object model), which improves application performance.

Stable code: By utilizing just descending information streams, React.js ensures code soundness and better application execution.

Designer toolset: React.js furnishes developers with high-performance design tools, guaranteeing better performance.

App development: By following similar plan designs, you can construct rich UI for native applications upheld by iOS and Android stages.

Advantages of React.js:

Better Efficiency:

The main benefit of React.js is that it allows you to keep all the parts that you made in its own virtual DOM. All the changes done in DOM are automatically updated in the DOM tree. It eliminates the time-consuming DOM activities and refreshes frequently.

These features help React.js to develop the effectiveness of applications or websites.

Web optimization Friendly:

Despite delivering an enormous number of JavaScript-based web and convenient applications daily, web indexes feel that it’s difficult to examine JS applications that are vastly significant.

Using React JS, you can make light-weight web and compact applications without a very remarkable stretch. One can run React JS on the server-side, and the virtual DOM will be delivered, which will return to the program as a standard site page.

Component-based Construction:

When you use this framework, you can easily make segments as per your requirements. These segments can later join your center substances. It allows you to create your components and display, combine, and integrate them into your core content.

React.js updates rapidly and ships well with smooth interface designs. It gives support to the client-side and the server-side. It allows you to reuse code and is view-oriented.

Limitation of React.js:

There are some shortcomings and limitations of React.js that would discourage you from using this framework.

Here are some disadvantages:

Difficult to learn:

The framework is quite complex and it requires in-depth knowledge for integration into a user interface free library.

Poor documentation:

React technologies have frequent updates and it accelerates rapidly. Due to this, there is no time for proper documentation.

View part:

React.js framework covers only the UI layers of the app. So, developers still need to use some other technologies to get a complete tooling set for developing a project.


In basic terms, it’s JavaScript’s free and open source cross-platform for server-side programming that permits clients to develop web applications rapidly.

It is a library for executing JavaScript applications and is used to create server-side programs or network applications. Its basic modules are engraved in JavaScript. It is generally utilized for server applications in real-time.

Node.js permits JavaScript to execute locally on a machine or a server. Before the Node was presented, the execution of JavaScript was not comprehensible on a framework since it remained customer-side language or program-based Language. It was just helpful for the creation and control of DOM components.

Node.js gives numerous systems to utilize for example koa, hapi, and so forth. One of such structures is Express.js. It is more valuable and mainstream than the different structures of Node.js.


Versatility: NodeJS is incredibly adaptable as the server reacts in a non-blocking way.

Zero Buffering: Applications at no time cradle information in Node.js. They just yield the measurements in enormous pieces. This gives the advantage of ‘No buffering’ to developers.

Network: Node.js upholds an open-source community. This is the main explanation that numerous glorious modules have been added to Node.js applications over time.

Occasion driven Input and output: APIs of Node.js are non-blocking. It implies that the server won’t hang tight for the arrival of information from an API. Rather, it will move to another API.

Advantages of Node.js:

Easy to learn:

Most front-end developers have a nice handle over JavaScript as it is one of the most notable programming dialects. It turns out to be simple for developers to utilize Node.js at the backend. Learning Node.js is less difficult and sets aside less effort to deal with.

Better Performance:

Node.js takes the code of JavaScript via Google’s V8 JavaScript engine. The main advantage of this process is that it complies with the JavaScript code directly into the machine code which makes it easier to implement the code effectively.

Node.js supports the non-blocking operations and due to this, the speed of the code execution is increased.


Node.js open-source network gives the office of storing single modules. Any solicitation for a module gets reserved in the application memory.

Because of this, the developers don’t need to re-execute the codes as reserving permits the applications to stack the pages quicker and react rapidly.


Node.js offers the opportunity for developers to create applications and programming. This element is generally gainful as different stages have certain constraints and don’t have this element.

With Node.js you can start everything without any preparation while creating applications.

Extended support for tools:

Another advantage of Node.js is that developers get support for the various commonly used tools. You can easily use the common tools on Node.js.

For example, if you want to test the source code, you can do it by using any unit-testing tools such as Jasmine.


The Node.js is known to be profoundly extensible, which implies that you can tweak and further broaden Node.js according to their prerequisites.

You can likewise utilize JSON to give the degree to trade of information between the web server and the client. It likewise is encouraged with built-in APIs for creating HTTP, TCP, and DNS and other servers.


One of the key preferences of Node.js is that designers think that it’s simple to scale the applications in horizontal as well as vertical directions. The applications can be scaled even by the option of extra hubs to the current framework.

Besides, Node.js additionally offers you the alternative of adding additional resources to the single hubs during the vertical scaling of the application. Thus, it is profoundly versatile and gives preferred alternatives to other JavaScript servers.

Limitations of Node.js:

Programming interface isn’t steady:

One of the key issues that an enormous bit of the originator’s involvement with Node.js is the Application Programming Interface (API) keeps changing at customary recesses and doesn’t remain stable.

Commonly, another API shows up having differences in invert incongruent changes. Thus, the designers are constrained to make changes in the accessible codebases to arrange the comparability with the latest transformation of the Node.js API.

No strong Library support system:

When compared with other languages, JavaScript does not hold a strong library system. This makes the users take the help of a common library for executing different tasks such as ORM, handling database operations, image processing, and XML parsing, etc.

This limits the developers to implement even common programming tasks using Node.js.

Programming Model is not synchronous:

Many developers find this programming model tougher in comparison to linear blocking I/O programming. In asynchronous programming, the codes become clumsier and developers have to depend on the nested calls.

Node.js has its advantages and disadvantages. The main element to look up is the fact that Node.js has extended the area of JavaScript application and it can be easily used for backend as well as frontend servers.

Which one is better?

React.js and Node.js both are popular frameworks used and applied for many successful businesses. However, if you need a better clarity to which framework you should use, here is some insight:

Node.js is a perfect framework when you want to develop a server-side web application like an online streaming platform.

React.js is best suited when you want to create a project with evolving states like dynamic inputs, buttons, etc.

You can also use both the frameworks for a single project. You can develop back-end with Node.js framework and can use react.js for developing the front-end of an application. The best example of such integration of frameworks is Netflix.

Both frameworks have large and active community support. The choice between the two depends on your need and requirement.
