NodeJs with React: Why React Developers Need NodeJs

8 min

To gain an edge in today's competitive tech environment, companies are targeting the most demanded tools. JavaScript is rapidly evolving, which is why many developers choose to use JS runtimes to build high-performance products. We are talking about Node.js with ReactJS, which have been at the peak of popularity recently. 85% of development teams reported using NodeJS for web development and 43% for enterprise development. In 2018, there were 24 million IT-specialists worldwide. The numbers speak for themselves.

So the fundamental question is: what is special about Node.js? What is its contribution to app development?

What Is Node.JS and Why it Attracts Technology Leaders

Almost all developers are well-familiar with JavaScript. Despite the emergence of other dynamic languages (PHP or Python), JS remains the main programming language.

Current software tools allow creators to use cutting-edge solutions. The main thing is that the code works correctly even in outdated browsers.

With NodeJS, you can implement the “JavaScript for Everything” paradigm. It assumes the use of one programming language for coding both the front- and back-end.

NodeJS is an embodiment of adaptive and scalable technology. This platform uses an open-source JavaScript engine. It is used to build high-speed scalable servers and cross-platform network apps.

The Node can be used as a programming language to write external and internal code for JS apps. This minimizes code duplication amid server and browser and dramatically reduces development time.

All built-in Node.js functionality is split into separate packages or modules. A module represents a block of code that can be reused in other modules. The engine uses an event-driven and non-blocking I/O model. Thus, it is perfect for creating contemporary solutions based on web-sockets, event queues, and microservices.

The Nodejs JavaScript runtime built runs on a single thread, just like the event loop. Yet, in the background, it can use many threads to execute asynchronous code. Thus, it behaves like a multi-threaded one. It does not wait for a response to an API call, I/O events, etc., and continues executing the code.

This allows many concurrent loops of connection events to be supported. Data is output in large batches, so applications do not suffer from buffering


These are based on Node.js:

  • Single Page Application (SPA). NodeJS can create SPAs that are indistinguishable from desktop applications. It is good for building social media, dynamic sites, and email solutions.
  • Chatbots. Node.js offers exclusive advanced features for real-time applications and chatbots.
  • IoT apps. NodeJS is known for its ability to successfully handle concurrent requests from one million devices on its network.
  • Backend for social networks. Node.js provides incredibly fast V8 routing along with secure authentication.
  • Streaming data. Node.js handles files at super-fast speeds and also ensures easy coding and uploading. This is appreciated by many online fashion stores and video streaming apps.

Companies searching for instruments to develop responsive apps will appreciate the tandem of Node.js and Reactjs. The advantages of it include a few thousands of libraries, the effectiveness of the simplified model, and the support of the NodeJS React community.

What Is ReactJS and Why Is It So Special?

ReactJS is a client side environment that manipulates the frontend based on the current state of the app. It is often used as a V in MVC because it uses fast virtual DOM. This simplified programming model provides improved performance. For example, this perspective technology is involved to display a news feed during a chat.

React is intended for use in the browser, but it can be rendered on the server as well. ReactJS's data and component templates help support complicated apps.

An innovation of React is component composition. And the components should work well together, even if written by different people. Components describe behavior that can be composited. This idea also extends to rendering, lifecycle, and state. The ability to split the app into separate modules allows you to think over the architecture of the app. It will be more resistant to changing requirements, and will also allow to divide the work among IT specialists.

Fundamental characteristics of React.js

Let's find out what the power of React.js is all about:

  1. Easy maintenance. React.js reuses components of a system and will update and display only what is needed when the data changes.
  2. Productivity. Virtual DOM improves application performance.
  3. The stability of the code. React ensures excellent performance of the code thanks to downstream data flow.
  4. Advanced developer toolbox. React JS provides all the necessary debugging tools for the convenience of mobile application developers. With the help of design patterns, it is easy to create an interface for applications on Android and iOS platforms.

Can I Use NodeJS With ReactJS and in What Cases?

Our team prefers to use Node.js along with ReactJS to create ergonomic interface components. ReactJS' code can run right in the NodeJS environment. The React DOM library has a special component for working with Node. It simplifies rendering and using generic/isomorphic apps. 

Remember that using React with Node (or any other backend) is optional. React is a Javascript library for presenting information to the user, and it doesn't matter where this information comes from. Node just makes it easier to build with React. Even if you're hosting a React app on a non-Node server, you can still use it to prepare JavaScript for deployment (on anything other than Node). So NodeJS is not necessary, but preferable, when using ReactJS.

Node vs React: A Minimal Code Ecosystem

Comparing Node and React with each other is not entirely appropriate. These are completely different things. The choice is dictated solely by your business need.

Here's what our developers have to say:

  1. If your goal is a complex, scalable server-side app, such as a real-time streaming platform, opt for Node.JS.
  2. If you need a stateful product with dynamic input, buttons, etc., React.js is a perfect choice.

In our opinion, combining these two can do miracles and save work hours. It is an effective solution for startups and complex ecosystems of leading enterprises. Using the tandem of React vs Node will move your app to the highest level.

Best-Known Projects Built with React+Node

You can safely use both technologies in web applications. The frontend can be written with React and NodeJS, a server-side environment, just like Netflix did.

Node.js has caught the attention of a variety of companies for a reason. The top businesses did a critical and important analysis before switching to Node.js. Netflix chief engineer Yunong Xiao says his choice was influenced by a significant reduction in launch times. Amazon chose Node.js for its futuristic characteristics.

Node.js has several other well-known users such as Trello, LinkedIn, and Facebook. Let’s find out why Node.js became their basic JavaScript runtime built.


This cloud service involved Node.js backend. Trello finds Node convenient for updates that need to have many open connections.


Node.js has enhanced LinkedIn performance by 20×. They reduced the number of servers from 30 to 3, lowered memory costs, and focused on application development rather than troubleshooting.


This online streaming giant chose Node.js for its rapidity and lightness. It helped Netflix to cut launch times by 70%. 


React is a perfect tool for creating interactive interfaces for sites and applications. Many of Facebook's dynamic elements are built with React.js.
