Can Reactjs Be Used for Server-Side Scripting?


Larry Thompson

ReactJS is a powerful JavaScript library that is primarily used for building user interfaces on the client-side. It allows developers to create reusable UI components and efficiently update the user interface when the underlying data changes. However, one question that often arises is whether ReactJS can be used for server-side scripting as well.

What is Server-Side Scripting?
Server-side scripting refers to the execution of scripts on a web server rather than on the user’s browser. These scripts generate dynamic content that is then sent to the client-side for rendering in the browser. Traditionally, server-side scripting has been done using languages like PHP, Ruby, Python, or Java.

ReactJS and Server-Side Rendering (SSR)
ReactJS was initially designed for client-side rendering, where the JavaScript code runs in the browser and generates the UI. However, ReactJS can also be used for server-side rendering (SSR), which means that React components are rendered on the server and sent as HTML to be displayed in the browser.

The Benefits of Server-Side Rendering with ReactJS
Server-side rendering offers several advantages over client-side rendering:

Improved Performance: By rendering components on the server, you can reduce the initial load time of your application. The user receives pre-rendered HTML content from the server, which can be displayed immediately while JavaScript bundles are being downloaded and executed.

Search Engine Optimization (SEO): Search engines primarily rely on HTML content when indexing web pages. With server-side rendering, your React application’s content is readily available as HTML, making it easier for search engines to crawl and index your pages.

Accessibility: Server-rendered content is accessible by default since it doesn’t rely solely on JavaScript execution. This ensures that users with assistive technologies or older browsers can still access your application’s content.

How to Implement Server-Side Rendering with ReactJS
To enable server-side rendering with ReactJS, you can use a framework like Next.js or Gatsby. These frameworks simplify the process of setting up server-side rendering and provide additional features such as static site generation and data fetching.

First, you need to set up your project by installing the necessary dependencies. For example, to create a Next.js project, you can run the following command:

  • Install Node.js and npm if you haven’t already.
  • Create a new directory for your project.
  • Open a terminal and navigate to the project directory.
  • Run the command: npx create-next-app

After setting up your project, you can start building your React components as usual. However, instead of exporting them for client-side rendering, you export them for server-side rendering using the `getServerSideProps` function provided by Next.js.

Here’s an example of a simple Next.js component that fetches data from an API and renders it on both the server and client:


import React from ‘react’;

export default function Home({ data }) {
return (

Welcome to my website!

{data && (

    { => (

  • {item.title}
  • ))}



export async function getServerSideProps() {
const response = await fetch(‘’);
const data = await response.json();

return {
props: {

In this example, the `getServerSideProps` function is used to fetch data from an API endpoint and pass it as a prop to the `Home` component. This function runs on the server before rendering the page, ensuring that the data is available when the page is first loaded.

While ReactJS is primarily known for its client-side rendering capabilities, it can also be used for server-side scripting through server-side rendering. Server-side rendering with ReactJS offers improved performance, better SEO, and enhanced accessibility.

Frameworks like Next.js and Gatsby make it easier to implement server-side rendering in React applications. So, if you’re looking to enhance your web application’s performance and SEO capabilities, consider exploring server-side rendering with ReactJS.
