How Ksolves Migrated Legacy Healthcare Application to Angular for Enhanced Performance & Maintainability
The client is a North American healthcare technology provider serving hospitals, clinics, and telemedicine platforms. Their legacy application, built on AngularJS with a monolithic backend, handled EHRs, patient scheduling, lab results, and telehealth workflows. The platform was slowing down with new feature demands, increasingly difficult to maintain, and struggled to deliver a smooth experience for clinicians and patients. The client sought a modern, scalable solution with better performance, maintainability, and compliance support.
- Outdated Frontend (AngularJS): The legacy framework lacked support for modern browser APIs, mobile-first design, and reactive programming, causing performance bottlenecks and rendering issues.
- Monolithic Codebase: A tightly coupled code structure made debugging difficult, delayed feature delivery, and increased maintenance overhead.
- Poor Mobile Experience: The application was not fully responsive, limiting usability for clinicians accessing patient data on tablets or phones.
- Data Handling Inefficiencies: The old app fetched entire datasets even for small views, leading to slow data rendering and high server load.
- Complex Integrations: Multiple third-party APIs for labs, insurance, and telehealth services had inconsistent formats and limited support for modern protocols.
- Compliance & Security Risks: Sensitive patient data needed secure handling; the legacy app lacked modern encryption standards and audit capabilities
Migrating a legacy healthcare application is never just a lift and shift. At Ksolves, we took a strategic, phased approach to modernize the platform while minimizing downtime and ensuring a smooth transition for users.
- Phased Migration to Angular 20: We gradually replaced AngularJS modules with modern Angular components, minimizing downtime and risk.
- Component-Based Architecture: Our Angular development team rebuilt UI elements as reusable components, allowing independent development and easier testing.
- Performance Optimization: We implemented lazy loading and AOT compilation for faster startup and used OnPush change detection and trackBy in ngFor to reduce unnecessary DOM updates.
- Efficient Data Handling: We refactored APIs to fetch only the data needed per view, and adopted RxJS streams for reactive, responsive data flows.
- Responsive, Intuitive UI/UX: Our team leveraged Angular Material and responsive design principles so the application worked smoothly on desktops, tablets, and smartphones.
- Modern Integrations: Further, we unified APIs with RESTful services, introduced error handling and retries, and ensured reliability through circuit breaker patterns.
- Security & Compliance: Lastly, our Angular developers added JWT-based authentication, role-based access control, data encryption, and audit logging, fully aligning with HIPAA and GDPR requirements.
- 50% Faster Page Loads: Clinicians now access patient data quickly, improving productivity.
- 40% Less Maintenance Overhead: The modular codebase allows developers to add features and fix bugs faster.
- Enhanced Mobile Experience: The fully responsive UI works seamlessly across all devices.
- Future-Ready Architecture: The platform is now scalable for new features like AI-driven patient insights or expanded telehealth services.
- Compliance Achieved: Patient data is secure, and audit trails meet strict healthcare regulations.
As a leading Angular development company, we turned a challenging legacy healthcare application into a modern, high-performance Angular platform. By taking a practical, phased migration approach, we not only addressed performance bottlenecks and maintainability issues but also strengthened security and compliance. The result is a scalable, future-ready application that empowers healthcare providers with faster, more reliable access to patient data, a smoother user experience, and the flexibility to integrate new features as the healthcare landscape evolves.
