Expert guides, proven playbooks, and real-world insights on migrating from Vue 2 to Vue 3. Learn from our experience migrating dozens of applications.
Switching from Webpack to Vite during a Vue 2 to Vue 3 migration: when to do it, plugin equivalents, path aliases, env variables, and how to avoid a double rewrite (compat mode + new bundler at once) without stalling the team.
Unit testing with Vue Test Utils 2, Jest or Vitest, and Vue 3: mounting script setup components, async suspense, teleports, and Pinia in tests. How to evolve tests when teams move from Options API to Composition API without rewriting the world.
Moving from Vue Router 3 to Vue Router 4 for Vue 3: new history API, dynamic route add/remove, scroll behavior, navigation guards, and the integration work that expands calendar estimates beyond "just the router package."
Move vue-i18n to the Vue 3 version: locale lazy loading, plural and ICU message formats, SSR-friendly locale resolution, and coordination with UI libraries (Element, Vuetify) during migration.
Adopt or tighten TypeScript while migrating Vue 2 to Vue 3: allowJs, shims, typed composables, and a ratchet that keeps the app shippable without a multi-month TypeScript detour before Vue 3 ships.
Apply the strangler fig pattern to Vue: route new work through Vue 3, leave legacy on Vue 2, and replace functionality incrementally. Shell apps, @vue/compat, and when to strangle a domain vs a route.
Run Storybook 8+ on Vue 3 to isolate component behavior before the big app cutover. Stories as contracts, visual regression, and how Storybook accelerates a Vue 2 to Vue 3 migration.
Vue 2 EOL and SSR: when server-side rendering and hydration become non-optional for performance or SEO, and what changes as you plan Vue 3, Nuxt 3, or a custom Node render pipeline.
Upgrading a Quasar v1 (Vue 2) app to Quasar v2+ on Vue 3: CLI, build targets, component API shifts, and Cordova/Capacitor—when the framework is your whole product stack, not a UI add-on.
How product and engineering align when Vue 2 EOL forces a migration: scope freezes, parallel tracks, and how to say no to new feature work in the hot path without tanking revenue.
Nuxt Bridge can help teams move Nuxt 2 code toward Vue 3, but it is not free. How to use it as a deliberate phase—and how to know when you are just deferring a full Nuxt 3 cutover.
Moving from Nuxt 2 to Nuxt 3 is not a Vue version bump: Nitro, new routing, composables, and module ecosystems change. A practical view of when it becomes a platform program—and how to scope it next to a plain Vue SPA migration.
When your product is already split as micro-frontends, Vue 2 EOL is a fleet problem. Here is how to migrate one deployable at a time, align shared dependencies, and avoid a distributed big-bang.
Hiring for Vue 3 and migration work in 2026: what to put in the job post, how to structure interviews, and how pairing on legacy Vue 2 code reveals the seniority you need—beyond buzzwords.
Upgrading to Vue 3 is not only runtime code—eslint-plugin-vue, Volar, TypeScript-aware rules, and Prettier alignment often consume more calendar time than expected. A practical order of operations.
A practical map for moving Element UI (Vue 2) to Element Plus (Vue 3) in large admin and data-heavy apps: tables, forms, i18n, message APIs, and phased rollout so the Vue core migration is not a second rewrite.
A practical approach to design tokens, shared components, and Storybook before a Vue 2 to Vue 3 upgrade—so the framework migration is not the same project as a UI redesign.
Component tests and Cypress CT after a Vue 2 to Vue 3 migration: when to lean on mount tests vs E2E, handling Teleport/fragments, and rebuilding stable selectors after the Options API to Composition API shift.
Enterprise MSAs, SLAs, and RFPs often require maintaining supported, vendor-backed software. Here is how Vue 2 end-of-life shows up in customer contracts, renewals, and security questionnaires—distinct from internal compliance audits.
After moving from Vue 2 to Vue 3, teams often expect a smaller JS payload and better Core Web Vitals. Here is what we actually measure, which metrics move first, and where post-migration perf still surprises you.
