Why Mobile Banking Apps Use React JS for Simplifying E-Banking MaintenanceWhy Mobile Banking Apps Use React JS for Simplifying E-Banking Maintenance

Is your financial institution on the fence about whether to work with a React JS specialist and if React is the best solution for maintaining your banking app? It is abundantly clear that the seascape of the banking world has undergone a tremendous metamorphosis over the past decade. It is often hard to determine whether something is just a fad or a fundamental innovation. 

There have been 4 billion finance app downloads across the iOS and Android platforms. At the same time, brick-and-mortar bank branches are closing around the world. There is a direct correlation between the two. 

People prefer the luxury of being able to bank anytime and anywhere, and smart devices and the internet have made this possible. This has made the demand for technical experts in mobile development a must in the financial services industry. In this article, we explore the benefits of using React JS for the development and maintenance of your mobile application. 

What Is React JS?

React JS is a JavaScript library, created by the developers at Facebook, to simplify the development of user interfaces. The two competitors in this space are Angular and Vue—at a distant third. React currently dominates the marketplace with more than double the users of Angular. 

React is a component-based library that builds applications by stacking components into one app. For instance, a bank app may partially consist of components like:

  • Navbox
  • Profile
  • My Account
  • Transfer Money
  • Loan Products
  • Contact

These components constitute the fundamentals of a basic e-banking app. The primary power of using the React approach to maintenance is that it uses both the Real Dom and a Virtual Dom. This is the key to the ability of React to maintain the stability of your website while changes are being made. 

The developer can make changes to the individual components in the Virtual Dom without directly impacting the website’s framework. When the changes are made virtually, the Real Dom reacts by automatically updating the change to that particular component. 

React vs. Angular

Over the past couple of years, React JS has overtaken Angular as the most-used UI development solution. React is a lightweight component creation tool that makes the process of building user interface components simpler. React is written using JSX and not HTML, so knowledge of this language is needed. For the maintenance of e-banking applications, the compartmentalized aspect of this library makes React JS ideal.  

Angular is a framework rather than a library. Its robust design is focused on building applications. The approach of Angular is all-inclusive and extensive. The options that Angular presents for full application development are undeniable. However, React JS has become popular when it comes to maintaining a UI for an e-banking app because of the fluidity and stability associated with its use of the Virtual Dom, giving it a clear advantage in this regard.

The most fundamental difference between the two is that React is a library for developing UIs, and Angular is a full framework for applications. The streamlined approach taken by React makes it most suitable for financial services and banking. This is why banks use React JS for mobile applications.

React for Financial Services Apps

Another reason that React has become so well used is the open-source nature, making it possible to add libraries and enhance the platform in a wide variety of ways. We have seen this done to tend to the needs of the financial services communities specifically. 

React JS has been enriched for the development of finance-based UI. React Native has become a popular iteration of the technology that financial institutions and service providers have used as part of the modularized codebase and attractive UI design kits for the design and maintenance of mobile banking apps.

A good example of how this technology has been enhanced to cater to the banking world is the React Native Finance App Template. The FinTech community is now using the multi-purpose facets of React Native explicitly tailored for developers of financial services and banking apps. 

Some of the FinTech app types that were made easier with React Native:

  • Investment portfolios
  • Crypto trading
  • Stocks trading
  • Market news
  • Personal capital progress
  • Banking features (checking/savings accounts, transactions)
  • Net worth tracking
  • Expense tracker
  • Budget tracker
  • Notifications

When you focalize your efforts to the crucial aspects of your product, you save time, money, and energy. When your objectives are clear, and you need a standard regulated approach to your user interface, React JS delivers in spades. The presets and plugin factors cut maintenance and development time down, thus cutting energy and cost. 

The buzz behind the React JS platform is warranted and alarming to all who have not begun to convert to the use of this tool in financial services. It is understandable for financial companies to want to proceed with caution when it comes to using unfamiliar technologies and approaches that may not withstand the test of time; however, we see something much different for financial companies and the incorporation of React. 


When it comes to updating and switching technologies, there is a lot to consider; however, the most significant consideration is whether the benefits outweigh the inconvenience of making changes to staffing or technical infrastructure. It should be apparent by now that the technology has moved forward, and React JS is the preferred platform in this day and time. When stability and efficiency matter, React JS seems to be the financial sector’s best option.
