Vue 3 Composition API enables scalable component structure through <script setup>, typed props, emits, and lifecycle hooks. This approach centralizes reactive logic, improves code reusability, and makes dependencies explicit compared to the Options API.

Composables are JavaScript functions that encapsulate and reuse stateful logic in Vue 3 using the Composition API. Common patterns include useAsync for data fetching, usePagination for handling pagination, useDebounce for input throttling, and useLocalStorage for persistent state across sessions.

State management in Vue 3 scales through Pinia store patterns with typed APIs and composables. This approach handles multiple concerns—reactivity, TypeScript typing for refs and computed values, error handling, and predictable API design—enabling maintainable stores across large projects.

Renderless components use slot-based patterns to separate logic from presentation, enabling flexible composition. A renderless DataFetcher, for example, handles data fetching logic while parent components control rendering, allowing reuse across different UI patterns without duplication.

Yes. Vue 3 Composition API provides full TypeScript support, including typed refs, computed values, and composable functions. This enables compile-time safety for reactive properties, lifecycle hooks, and form validation, reducing runtime errors in large applications.
