Real Problems From Real Vue Developers
These quotes are from r/vuejs this week. Sound familiar?
"Vuetify 2 doesn't work with Vue 3 and Vuetify 3 is a complete rewrite of every component"
"Migrating from Vuex to Pinia while also upgrading Vue 2 to 3 is a nightmare of breaking changes"
"Half our Vue 2 plugins don't have Vue 3 versions yet and the compatibility build has quirks"
"Vue Router 3 to 4 changed the entire API, navigation guards work differently now"
"Our Nuxt 2 app needs Vue 3 but Nuxt 3 is a ground-up rewrite, not an upgrade"
"Vue Test Utils v1 vs v2 — every single test file needs changes after the upgrade"
Vue 3 Upgrades Are More Than Just vue@3
The Vue core upgrade is one step. Your router, state management, UI library, and test utils all need to align.
