Node JS VS React: What’s the Difference and Which One to Choose for Your Project?
Table of Contents
Node.js and React are both popular and widely used. The comparison between them isn’t new, but it’s worth attention. The only question is, “Can we compare them?”
So, let’s define their difference. Node.js is a back-end platform for handling server-side operations, while React.js is a front-end library used to manage the user interface. Technically, they’re different and not interchangeable. But we’ll give you a spoiler; they can complement each other in your project.
If you’ve asked yourself at least once, “Which framework should I choose for the project” the article is a partial answer. Here, you’ll better understand the features of Node.js and React.js and set the goals you want to achieve.
Overview of Node.js
One article isn’t enough to describe all the features of Node.js and React, so we’ll focus on the most important ones.
Node.js is an open-source, cross-platform JS runtime environment for web apps outside the client’s browser. Large companies like PayPal, LinkedIn, Netflix, and Medium use Node.js. An event-driven and non-blocking input/output model makes the platform easy to start and lightweight. Event-driven means you make a call, and the Node.js server gets the request and registers an event. The event will be called when the fetching is completed. So, Node frees the event cycle to perform the next request. Developers use the platform to host APIs, serve HTTP requests, and access the database. Node.js works well for fast and scalable services and server-side apps like video streaming sites, single-page apps, online chatting apps, and others.
Here are the following features of Node.js:
Fast and open-source
Node.js runs on Google’s V8 engine (or Chakra from Microsoft), compiling JS into machine code and making it run efficiently and fast. The open-source opens access to thousands of community-tested software at no cost. But it’s not only about the price. With open-source Node.js, you get flexibility, scalability, and compatibility.
Since Node is based on JS, you can use the same language for back-end and front-end development. It enhances the app’s productivity, allowing you to perform non-blocking operations. Well, what does this set of words mean?
Let’s explain the difference between blocking and non-blocking operations. Technically, a blocking call waits for the completion of the input-output operation before returning; its results return synchronously.
In contrast, the non-blocking call returns directly without results, asynchronously. It means you can read files, send emails, query data, and perform other operations simultaneously. You can start the next task before the completion of the previous one.
In our blog, we discuss the pros and cons of Node.js for web app development. Read the article.
Implemented in JS
Better user experience
The server built with Node.js doesn’t need to wait for data from an API. What’s more, any input/output operation doesn’t block work. As mentioned above, you can perform any action without waiting until the previous task is completed. In Node.js, all operations are performed asynchronously. Thanks to it, Node.js responds quickly and offers a better user experience.
Node.js Package Manager (NPM)
NPM is a package of ready modules. Imagine NPM as a huge room where programmers share their code. It allows new projects to avoid writing the same components.
Node.js balances active central processing unit (CPU) cores and provides high customization. The platform handles multiple requests simultaneously with native tools like clusters, child_process, and worker_threads. Even a significant increase in requests doesn’t impact the load on the central processor, making it easy to develop scalable apps.
Node.js is compatible with many systems, from Windows and Mac operating systems to mobile platforms. Multi-compatibility with different platforms creates a self-sufficient environment for developers.
Overview of React.js
You get enhanced performance thanks to Virtual DOM (Document Object Model), a lightweight version of a real DOM. DOM is a programming interface allowing you to create, modify, or remove elements from a document. The virtual DOM signifies a programming concept where the “virtual” representation of a user interface is stored in memory and synced with the “real” DOM by the library. If we need to change the web page elements, we first make these changes in the virtual DOM. Then, if there’s a difference between the new state of the virtual DOM and the current state, React suggests and executes the needed manipulations to update the real DOM to a new state. The virtual DOM takes up little space and updates quickly, allowing the page to get responses from the server. Thanks to virtual DOM, Facebook updates users’ chats and feeds without reloading the page.

Effective for ranking on Google
In combination with Node.js, React renders the code from the server as a regular web page. So it’s easy for the browser to read your app.
Straightforward development process
React has a modular structure for any web app. The development with React.js is centered around the components. You can create components (pieces of code) once and reuse them many times in other apps. With React, you develop complex interfaces from small pieces of code, which we can compare to lego. These components are easy to assemble, reuse, manage, and test. Since they’re reusable with high logic and control, it helps us to work even on large projects, thus keeping the code clean and stable.
Declarativeness of React is when we use code to say what results we want to display on the page. In the case of declarative programming, we don’t set instructions on how to implement the results.
Node JS vs. React JS Comparison
Should we call Node.js and React competitors? The answer is no. They’re reasonable solutions for diverse projects but serve different functions. And we’d like to show Node.js vs. React comparison based on the parameters below.
The learning curve
The learning curve of React.js and Node.js is almost the same, with the only difference. React.js makes web development easy to implement because of well-detailed documentation and simple design. Node.js is also easy to learn, but developing and deploying apps may take more effort because of the asynchronicity of Node.js. But since Node.js increases app productivity and allows you to reprocess the code, it greatly simplifies development.
App size and performance
App size and performance directly influence your app’s load and response time. In the case of React, thanks to the virtual DOM we discussed earlier, the library is great for managing regular user interface updates. The virtual DOM improves app performance through its ability to take minimum space and update fast. As for Node.js, it increases its productivity with time and satisfaction among users. Thanks to the asynchronous and non-blocking model, and reusable code, it makes real-time updates. As a result, it also boosts productivity and reduces development costs.
Node js vs. React: Which Is Better?
When using technology, a factor requiring attention is the community around the framework. The best about React and Node.js is that both have huge teams regularly supporting them. You don’t have to worry about malfunctions in the app. Since the community always makes regular updates, with its support, you get the best tips and tricks at your disposal.
So, when we talk about React.js vs. Node.js, which is better? What if using both technologies in a single project? As in the case of Netflix. It uses Node.js to reduce launch time and the React.js library to boost speed and performance. So making a similar comparison isn’t proper.
Many businesses apply Node and React. But to define the proper technology for you, you need to define your priorities and the features you want to see in your project. For a complex and scalable back-end web app, Node.js works well. For a project with dynamic and changing states, like inputs or buttons, React is ideal. Simultaneously, you can use both, as in the case of Netflix, Uber, and Twitter.
Here are 4 reasons why Node.js and React development work excellently together:
- While using React and Node.js, you get a universal JS application, and the development is easier.
- Thanks to Node.js, code compilation and execution are easy because the framework bundles React app in a single file.
- By combining technologies, you create a front-end with React and a back-end with Node.js.
- Node.js manages bulk requests, minimizing the response time of the app.

Give It a Go
The Node.js vs. React comparison isn’t correct because these technologies are completely different. It’s the same as comparing a car with a bicycle. Both are good but used for various purposes. All you need to do is choose between them, focusing on specific factors or mixing them to cover different goals.
