You can build Vue 3 components using plain JavaScript by leveraging JSDoc annotations for type safety. This approach provides IDE type hints and enforces strict type coverage for props and emits without needing a TypeScript compiler.

The best way to maintain type safety without TypeScript is using JSDoc-driven typing. By applying @typedef and @param annotations, you achieve full type coverage and standardized documentation for public APIs in your Vue 3 application.

Yes, you can use JSDoc annotations to type composables in a Vue 3 script setup. This enables strict type checking and modular ESM structure for .mjs modules, ensuring robust IDE support while keeping a vanilla JavaScript codebase.

Vue 3 supports automated linting verification for JSDoc type annotations through specialized workflows. This enforces strict type coverage for props, emits, and composables, ensuring your vanilla JavaScript codebase meets standardized documentation requirements.

Using JSDoc instead of TypeScript during a Vue 2 to Vue 3 migration lets you adopt the Composition API while keeping your existing vanilla JavaScript codebase. It provides robust IDE type hints and enforces type safety without introducing a TS compiler dependency.

You generate Vue 3 composables with JSDoc-typed state management by creating .mjs modules with @typedef and @param annotations. This approach provides full type coverage and standardized documentation for public APIs without requiring a TypeScript compiler.
