Vue 3 and Typescript
summary
Vue 3 claims full TypeScript love: core and official libs are rewrote core in TypeScript, the Composition API yields real inferred types, injections use InjectionKey so inject(...) is typed, and template props now produce editor errors and safe renames. Tooling options include Volar and Vetur and a CLI vti for template type checks. Surprising numbers: TypeScript ≈16 million weekly downloads while Vue is ≈2 million, and ~30–40% of npm packages ship types. Caveats remain: template build-time typechecking and Vuex 5 typing are still work in progress.
