Case Study: AngularJS to Angular Migration
Transform Your Legacy Systems with Seamless Modernization: A Success Story in Insurance Tech
Client Challenge
A leading insurance provider specializing in Medicaid, Medicare Advantage, and Health Insurance Marketplace solutions faced critical limitations with its legacy claim management system. Built on AngularJS 1.5 and .NET 4.7, the application struggled with performance bottlenecks, scalability issues, outdated security protocols, and compatibility challenges with modern cloud-ready architectures. The monolithic structure hindered innovation, while aging frameworks like WebAPI 2.0 and jQuery-based UI workflows demanded urgent modernization to stay competitive.
Our Solution
Partnering with Macrosoft, the client embarked on a strategic migration to Angular 18 and .NET 8, unlocking next-gen capabilities:
✅ Performance Optimization: Replaced AngularJS’s two-way data binding with Angular’s reactive state management (RxJS/NgRx), reducing UI rendering delays by 40%.
✅ Modular Architecture: Transitioned to a component-based structure with lazy loading, slashing initial bundle sizes and accelerating load times.
✅ Enhanced Security: Integrated JWT/OAuth 2.0 authentication and HttpClient interceptors to mitigate XSS/CSRF risks.
✅ Future-Ready Backend: Upgraded APIs to RESTful standards using .NET 8 and Entity Framework Core, ensuring seamless cloud deployment via Azure.
✅ UI/UX Modernization: Leveraged Angular Material and Bootstrap to deliver a responsive, intuitive interface aligned with modern design principles.
Overcoming Complex Challenges
The migration tackled masked data constraints, non-standard APIs, and intricate business logic through:
🔧 Incremental Hybrid Migration: AngularJS-Angular coexistence ensured zero downtime during the transition.
🔧 Automated CI/CD Pipelines: Integrated Jest, Cypress, and Selenium for rigorous unit, E2E, and regression testing.
🔧 Phased Rollout: A pilot-to-full deployment strategy minimized risks, supported by real-time monitoring via New Relic.
Results
The client now operates a high-performance, scalable claims processing platform with:
✔ 40% faster claim processing via optimized APIs and state management.
✔ Robust security compliance meeting healthcare industry standards.
✔ Streamlined maintenance through TypeScript-driven code and Angular CLI automation.
✔ Seamless scalability for future enhancements in a cloud-native ecosystem.
