Upgrading to Vue 3 brings a proxy-based reactivity system and compiler optimizations that lower CPU and memory usage. In large-scale applications, we’ve measured 10–20% faster render times and smaller JavaScript bundles — improving Core Web Vitals, mobile UX, and overall frontend performance.
Moving from Vue 2 to Vue 3 with the Composition API, stronger type safety, and modern tooling results in fewer regression bugs and smoother onboarding for new developers. Routine updates stop breaking unrelated parts of the system, cutting long-term maintenance costs.
A Vue 2 to Vue 3 migration removes dependency blockers tied to outdated libraries. You can adopt modern UI frameworks (e.g., Vuetify 3, Element Plus) and new Vue.js ecosystem features without major rewrites, keeping your tech stack current.
Better code organization, first-class TypeScript support, and predictable state management patterns (Pinia, <script setup>) enable faster delivery of new features and reduce context switching for your development team. Our Vue.js senior developers leverage these capabilities to help your team ship high-quality features faster and with greater consistency.
