Does React App Need a Web Server?


Heather Bennett

React is a popular JavaScript library used for building user interfaces. It allows developers to create dynamic and interactive web applications with ease.

But when it comes to deploying a React application, one might wonder if a web server is necessary. In this article, we will explore whether a React app needs a web server or not.

What is a Web Server?

Before we dive into the specifics of whether a React app needs a web server or not, let’s first understand what a web server is. In simple terms, a web server is a computer program that serves files and resources over the internet. It listens for incoming requests from clients (such as web browsers) and responds by sending back the requested files.

React Development Server

During development, React provides its own built-in development server called Webpack Dev Server. This development server allows you to run your React app locally and provides features like hot reloading, which automatically refreshes the page whenever you make changes to your code.

The React development server also takes care of bundling and serving your static assets like HTML, CSS, JavaScript files, and images. It simulates the behavior of a production web server and makes it easy for developers to test their apps without having to set up an actual web server.

Using the Development Server

To start the React development server, you need to have Node.js installed on your machine. Once you have Node.js installed, navigate to your project’s directory in the command line and run the following command:

npx react-scripts start

This command will start the development server at http://localhost:3000. You can open this URL in your browser to view your React app running locally.

Production Deployment

When it comes to deploying a React app in a production environment, you have a few options. While it is possible to serve a React app using the built-in development server, it is not recommended for production use.

In most cases, you would want to use a dedicated web server like Apache, Nginx, or Express.js to serve your React app. These web servers are designed to handle high traffic and provide better performance compared to the development server.

Build Process

Before deploying your React app using a web server, you need to build your application. The build process generates optimized and minified versions of your static assets, making them more efficient for production use.

To build your React app, navigate to the project’s directory in the command line and run the following command:

npx react-scripts build

This command will create a build folder in your project’s directory with all the necessary files for deployment.

Serving the Built App

To serve the built React app using a web server, you need to configure the server to point to the build folder generated during the build process. The exact configuration depends on the web server you are using.

  • Apache:
        <VirtualHost *:80>
          DocumentRoot /path/to/your/react-app/build
  • Nginx:
        server {
          listen 80;
          root /path/to/your/react-app/build;
  • Express.js:
        const express = require('express');
        const app = express();
        app.listen(3000, () => {
          console.log('Server is running on port 3000');

Once your web server is configured, you can access your React app by visiting the domain or IP address associated with it. The web server will handle incoming requests and serve the appropriate files.


In conclusion, while a React app does not necessarily need a web server during development thanks to the built-in development server, it is highly recommended to use a dedicated web server when deploying your app in a production environment. These web servers provide better performance and scalability, ensuring that your React app runs smoothly even under high traffic conditions.

By following the proper build process and configuring your web server correctly, you can serve your React app to users around the world and provide them with an exceptional user experience.
