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.
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.










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.
