How to Seamlessly Migrate a Large Codebase to Vue 3
summary
Crisp migrates a 250K-line app to Vue 3.2 in about two weeks, keeping production running on master while developing a Vue 3 branch and porting fixes back; the process uses vue-compat with per-feature disable plus Vue CLI, webpack, Vuex/Vue Router v4, and forks of a few libraries (e.g. vue-chartist). Specific wins: 250K lines → Vue 3.2 in ~2 weeks, migrated ~200 filters to JS utilities and a global $filter object, and measurable runtime improvements with minimal customer impact.
