Financial organizations are on the hook to keep up with a breakneck ride of technology innovation to ensure their security, scale, and seamless experience. In a competitive market like this, running critical applications on outdated frameworks like AngularJS means more risks, slower performance, and mounting maintenance issues. If you use AngularJS for your financial application, your priority should be migrating from AngularJS to Angular.
As Google officially ends AngularJS support by December 2021, organizations are creating their AngularJS to Angular migration plan to avoid falling behind the curve of technical obsolescence. Angular offers enhanced security, modern features, and long-term support, making it the ideal choice for financial applications in today’s dynamic digital landscape.
In this blog, we examine why financial applications must migrate from AngularJS to Angular, the impact on the business of not upgrading to the latest frameworks, and how a well-thought-out Angular migration plan can help ensure a smooth and future-ready upgrade.
In 2010, AngularJS was one of the first open-source JavaScript frameworks to be launched. However, the technology landscape has changed dramatically, and applications built with AngularJS face major hurdles today:
Angular isn’t a new version of AngularJS but a framework reimagined for modern web development. Here’s why financial institutions should consider moving from AngularJS to Angular:
Robust data protection protocols depend on financial applications. Cross-site scripting (XSS) prevention and content security policy are included here to help with sanitizing input, but there’s more. Second, regulatory compliance and the security of sensitive customer data should be easier to meet and protect against.
Within version 9, Angular has introduced its Ivy renderer, giving you faster application boot times and better runtime performance. Angular is also excellent at dealing with high user demand and large data sets because financial dashboards, trading tools, and transaction-based applications can handle the two well. Further, features such as lazy loading ensure that only the most crucial components are loaded for the first time, and so on.
The good news with Angular is that you have the assurance of long-term support from Google, which ensures that your applications will always be updated with new features and problem fixes. In addition, this framework agrees with modern technologies like DevOps pipelines and can adapt to business needs.
Incorporating TypeScript by Angular means code quality will be improved, and bugs will be flagged and removed early during development. In financial systems, this is critical, as even a tiny error can cause severe business disturbances.
Angular allows for easy and convenient division of the application into small modules that are reusable, significantly promoting faster feature development and enhancing the maintainability of complex financial systems.
Migrating from AngularJS to Angular is a massive technical project that needs proper planning and deployment. This is why having a good plan is essential if you’re migrating AngularJS to Angular. Here’s how to approach it:
Start with analyzing the structure, dependencies, and responsible functionalities of your AngularJS application. Find out which components can be removed, old libraries, and parts that need to be remade.
Start by trying to move security-critical modules and customer-facing functionalities first. For example, if the financial app performs transactions or displays the live stock market feed, these should be migrated first.
Angular includes tools that help to migrate within AngularJS and Angular in the same application. This approach enables phased development in hybrid, reducing downtime but also ensuring a less painful transition.
Error in financial applications is not allowed. Each step migration must be tested completely to check functionality, performance and security. Use Smoky, Selenoid, or their local modules with Protractor or Cypress for end-to-end testing (E2E) to have better chances to be successful in integration.
Technical debt is the perfect thing to clean up when you are migrating. Redesign legacy components, remove no longer supported dependencies, and use Angular’s best practices for better performance.
Investing in a robust AngularJS to Angular migration plan yields significant business benefits, particularly for the financial sector:
HSBC successfully transitioned its online banking portal from AngularJS to Angular, achieving remarkable results. The migration led to a 40% improvement in overall performance, significantly enhancing the speed and responsiveness of the portal. Additionally, development time was dramatically reduced, allowing HSBC to deliver new features and updates faster, improving customer satisfaction and maintaining its competitive edge in the digital banking space.
PayPal, a global leader in online payments, embraced Angular to modernize its transaction platform. This migration improved platform reliability by 35%, ensuring smoother and more secure payment processing for millions of users worldwide. The enhanced stability also enabled PayPal to scale its operations effectively, handling higher transaction volumes without compromising performance.
Standard Chartered leveraged Angular to create its next-generation customer portfolio dashboard. The migration significantly improved data rendering speeds by 50%, empowering clients to make informed, real-time decisions about their investments. This upgrade not only elevated the user experience but also solidified the bank’s reputation as a leader in delivering cutting-edge financial solutions.
For financial institutions, moving to Angular isn’t just a move to a modern framework; it’s a move to futureproof their business. Angular’s robust security features, exceptional performance capabilities, and reliable long-term support make it the ideal framework for building future-ready financial applications.
Migrating from AngularJS to Angular ensures your organization is well-equipped to handle the challenges of an industry that demands seamless user experiences, scalability, and airtight data protection. By adopting Angular, financial institutions can:
