Why to Choose React js for Single Page Application Development



June 20, 2022


June 20, 2022

React is the frontend JavaScript library maintained by Meta and the community of individual developers and companies. The library is used for building single-page applications, it manages the views of web apps and helps to modify the data without page reloading. 

If you want to explore more about single-page application development with React this article is for you. So let's explore more about single page application development, why React.js is preferred by most developers to build SPAs, the best example of single page application, and its benefits.

But, what is single page application?🤔

A single page application is a web application or website that interacts with the end-user through the browser by dynamically rewriting the current web page with the new data from the server instead of reloading the entire web page. 

That means the page refresh never occurs, instead, the necessary HTML, CSS, and Javascript code are retrieved or dynamically loaded to add at the necessary locations on the page. It improves the response time with faster transition giving native look and feel to your app.

Why React.js for single-page application development?⚛️

React.js can be used for almost anything from single-page web apps to highly complex enterprise applications to native apps. However, it is getting very popular due to its SPA development capabilities and higher performance. 

The library has a strong foundation and is evolving gracefully as an ecosystem of the libraries, tools, and frameworks like Redux, React Router, Material UI, Grommet, Ant design, etc. Also, the Code written in React.js can coexist well with the markup rendered on the server using client-side libraries. 

Let’s look into some of the top reasons behind choosing React for single-page application development.

1. React.js Components

React.js is a component-based framework that allows developers to break its UI into several small reusable components simplifying app development and testing. If any changes are made in a particular part of the application it will not affect the other parts of it. 

Its JSX extension allows you to write your code with loosely coupled components, these components accept HTML and make subcomponent rendering easy. In short,  it enables developers to write custom components to build complex, high-volume applications.

2. Higher Performance

React uses a virtual representation of DOM rather than directly manipulating it on user interactions. It allows testing all the changes to the virtual DOM first, letting developers calculate the risk of modification in advance. 

As a result, only the required changes are rendered to the web page by performing the operations on virtual DOM, increasing the app performance and guaranteeing a better user experience.

3. Better code stability

React allows only one-directional data flow, and uses downward data binding to ensure any changes in the child don't affect their parent. So, whenever the developers make changes to the object they only need to modify its state with a proper amendment providing better code stability.

4. React developer tool

What if you have great technology but don't have enough tools to analyze and test its implementation. Facebook understands this requirement and came up with the React developer tools and Chrome dev tools. 

These tools help developers to find the child and parent components, view component hierarchies, and inspect the component’s state and props. 

5. Simplified testing

The application built using react is highly testable, facilitating faster development and delivery of apps. It is one of the top reasons why it is preferred by enterprises looking to release their web app faster to the market while ensuring better quality.

6. Rich user interface development

The user interface in an app plays an important role in the app's success. It is the frontline through which users consume your services and have interactions. The poorly designed UI may badly impact your brand business. React.js framework enables you to build interactive UI using its declarative components.

7. Blacked by an active community of developers

React.js has active community support. The ecosystem has numerous packages for testing, UI animation, and more. Currently React has 189,000 stars and 1,558 regular contributors on GitHub. Not only that, Facebook is constantly taking efforts to develop and improve the Library by getting Feedback before releasing the new features. 

 React.js experts are constantly uploading React tutorials and answering developers' doubts on the different social and professional interaction channels such as Youtube, Stack Overflow, and Quora. That means you will never find yourself stuck in the problem.

The best example of single page application 🌐

If you are still not sure about using the React.js library for single-page application development here is the best examples of angle page application that uses React.js.


The news feed of Facebook is the instance of single page web application. The resources are loaded as you scroll down, you do not need to click open a new window or leave the page. 

Other websites using React.js technology in their web application are- Instagram, Netflix, Airbnb, Tesla, Yahoo! Mail, NASA, New York Times, Paypal, and Lyft.

Today, you can find that thousands of companies including 500 fortune companies are using React.js and React native for their web and mobile application development.

Benefits of using single page application 😀😍 

In the SPAs page resources such as HTML, CSS and scripts are loaded just once and only data is transmitted from server to client and vice versa.

1. Speed

As the page resources are loaded only once throughout the application rather than loading it multiple times, the app works faster and gives a seamless user experience.

2. Offline accessibility

Even if the application loses internet connectivity, its local storage cashes data that can be used when the app goes offline.

3. Uses less bandwidth

SPAs consume less bandwidth than traditional apps as it loads web pages only once, that's the reason it works best even in the areas with poor internet connectivity.

4. No need to write an extra line of code

SPAs eliminate the need to write code for rendering pages on the server and simplify app development activity.

5. Easy debugging

SPA simplifies debugging applications with the Chrome tool. It facilitates investigating page elements and monitoring network operations.
