You can build Vue 3 apps with JavaScript and JSDoc typing by using JSDoc annotations for type hints within script setup components. This approach provides type safety and maintainability without requiring TypeScript, leveraging plain JavaScript and .mjs modules.

Yes, you can migrate from Vue 2 Options API to Vue 3 Composition API without using TypeScript. This approach provides example patterns for migrating components, composables, and stores using plain JavaScript with JSDoc annotations for robust typing.

Vue 3 works seamlessly with Vite, Vue Router 4, and Pinia when avoiding TypeScript. You can maintain modern tooling and state management using JavaScript combined with JSDoc typing and the Composition API.

The best way to get type hints in Vue 3 script setup without TypeScript is using JSDoc annotations. By adding JSDoc comments to your plain JavaScript components, you enable robust tooling support via ESLint for well-documented, maintainable code.

Using JSDoc typing in Vue 3 JavaScript projects provides well-documented code and maintainability for teams avoiding TypeScript. It satisfies the requirement for typed JavaScript without the overhead of switching to a new language, keeping your modern Vite stack intact.
