In the digital era, users have high expectations when it comes to website performance. They want websites to load instantly and respond to their actions in real-time. This has pushed developers to find ways to meet these increasingly high standards. Over the last ten years, numerous JavaScript libraries and frameworks have emerged aiming to enhance website performance and interactivity.

While some of these technologies have fallen by the wayside, others have gained traction and are now used by web developers worldwide. One such technology is React.js, an innovative JavaScript front-end library created by Mark Zuckerberg’s team. Here is why: 

The Key Reasons to Choose React

  • React’s documentation is comprehensive, covering all aspects of using this library. 
  • React is preferred by several leading global companies, including eBay and Adobe, which prompts regular, thoroughly-tested updates. 
  • React.js has a mobile counterpart – React Native. This enables developers to create a single app for iOS and Android simultaneously using only React and JavaScript. This approach can save money and time as you only need to engage React developers instead of two separate native mobile development teams. 
  • React is currently very popular, making it easy to find experts to build a website using React. 

Given these strengths and more, increasing numbers of companies are selecting React.js for their web projects. But, is React a universal solution? Can it cater to all the different types of websites, such as portfolios, galleries, media sites, business directories, blogs, etc.? The answer is, “Yes, almost always.” For some, though, React is undeniably the best choice.

Let’s examine common scenarios where you might prefer React over other options.

The Most Common React Use Cases 

#1: You’re Building a New Social Network

If you aspire to create a new social network like Facebook or Instagram, React.js is the perfect tool. Social network users expect their actions, like giving a thumbs up or down, to be reflected instantly.

Traditional methods would necessitate one server request per user action, followed by a complete page reload. This process is time-consuming and slows the website down. React, on the other hand, excels at creating Single Page Applications (SPAs).

The advantage of an SPA is that once the main JavaScript file is loaded from a server to a client, all the action occurs in the browser. There’s no need to re-render every element on a page. React monitors for any changes and updates only the affected page components. This is made possible by the Virtual DOM, a feature beloved by React developers.

#2: You Need a Data Visualization Tool to Monitor Your Business KPIs 

Every business, big or small, generates a significant amount of data related to its operations. Keeping track of all this data can be challenging.

The optimal solution is to compile these figures into a single location and display them visually, like on a dashboard. React is ideally suited for this task as it can handle frequent data updates without needing to reload the entire dashboard every time there’s a change. Key features enabling React developers to achieve this include:

  • Virtual DOM. Only elements that have new data are re-rendered, speeding up the update process and allowing real-time changes. 
  • Server-side rendering. Without delving too deep into technicalities, React developers can run identical JS code on both the host and in a browser. This eliminates the blank page issue during dashboard loading and operation stages. 

#3: You Need to Quickly Develop a Mobile App That Complements Your Website 

Today, having a mobile app alongside a website is common, especially for eCommerce businesses. Here are some ways to do this:

  • Build separate native apps for Android and iOS – a costly and time-intensive option. 
  • Create a hybrid app using standard web technologies (HTML, CSS, and JavaScript).
  • Develop an app for both iOS and Android using mobile frameworks like React Native. React.js and React Native are akin to elder and younger siblings. The latter utilizes the React.js library, so a React developer familiar with JavaScript can quickly master React Native.

    While React Native has its unique features (for example, it doesn’t use HTML), it adheres to the same architectural principles as React.js. Consequently, you can swiftly develop a mobile app that’s virtually identical to an Android or iOS app.

#4: You Want to Sell Products Online

Using React.js library in your online store can significantly enhance the functionality and user experience. This is largely due to its component-based structure, which is akin to individual apartments in a building complex.

The benefits of using React components in your e-commerce platform are threefold:

  1. Sustainability: If a single component malfunctions, it doesn’t disrupt the performance of the remaining components. This resilience counteracts a common issue with traditional web platforms where an error in one area halts the entire system’s operation.
  2. Reusability: Developers can easily transfer an existing component to another website or application, accelerating the development process. Imagine your site as a modular construction set – you can adjust existing React components to meet specific business requirements.
  3. Responsiveness: Components can swiftly respond to changes within their designated scope. For instance, a component containing a form could display distinct notifications to different users based on whether the form was accepted or rejected without necessitating a page reload.

Overall, React components expedite the development of online stores and ensure their efficient, speedy performance. This gives you a significant competitive advantage.

When Should You Consider React.js?

  • Consider engaging a React JS consultant if your project involves a complex user interface. Traditional tools may struggle to manage such tasks effectively. React, with its flexible components, enables the creation of any site architecture, regardless of complexity.
  • React is also a good choice for highly interactive websites with many dynamic elements – buttons that are enabled or disabled based on user responses, form fields that appear or disappear for individual users, navigation items that highlight or fade, and so on.
  • Choose React for projects that involve frequently updated data that needs to be viewed in real-time. Thanks to its virtual DOM and server-side rendering capabilities, users won’t encounter blank pages.
  • React is optimal for rapid site assembly, like creating a Minimum Viable Product (MVP) to test a hypothesis. A React development team can achieve this by incorporating ready-made components into an existing site.
  • Finally, businesses planning future expansion will benefit from React. Even if they just have a simple, static site currently, React can be used to add new features and increase site complexity and interactivity, enhancing engagement with the target audience as the business grows.

Conclusion

React.js is a powerful tool that offers a myriad of benefits for businesses seeking a robust and efficient solution for their web and mobile application needs. Whether it’s creating highly interactive interfaces, data visualization, rapidly developing mobile apps, building online stores, or planning for future expansion, React.js provides a valuable solution. 

Incorporating the component-based structure, virtual DOM, and server-side rendering capabilities, React.js ensures high performance, reusability, and sustainability of applications.
