Challenge

XLenz had a massive legacy application on Nuxt 2 that was becoming increasingly difficult to maintain. Performance was degrading as the app grew, and they needed to migrate to Nuxt 3 while maintaining 100% feature parity. The migration had to happen without any downtime or disruption to their enterprise clients.

Our Process

Migrated from Nuxt 2 to Nuxt 3 with Vue 3 Composition API. Integrated AG Grid Enterprise for advanced data tables with sorting, filtering, and grouping. Implemented selective rendering using Nuxt generate for static pages and server routes for dynamic content. Built custom widgets using TypeScript for type safety. Node.js backend integration for API communication.

Reviewed the product goals, user paths, and existing technical constraints.
Mapped the core workflows before changing the interface or architecture.
Built the highest-impact screens and features first so stakeholders could test early.
Connected the frontend to real data, APIs, and content systems instead of static mockups.
Checked performance, accessibility, and responsive behavior across key breakpoints.
Prepared the project for launch with clear handoff notes and maintainable code.

Conclusion

The Solution

Led the migration by first auditing the entire codebase and creating a comprehensive migration plan. Implemented a hybrid SSG/SSR strategy where static pages were pre-rendered at build time while dynamic user dashboards used SSR. Rebuilt complex data widgets using AG Grid for better performance with large datasets. Created a parallel deployment strategy that allowed gradual rollout to users. The migration resulted in 40% faster initial page loads and 60% reduction in client-side JavaScript.
