Vue 3 components use the Composition API to define props, emits, and slots within .vue files. This approach enforces consistent conventions for component architecture, replacing the Options API with composable logic for better reusability.

Testing Vue 3 components with Vitest and Vue Test Utils involves validating implementations through consistent testing practices. You write unit tests that mount components, simulate interactions, and assert emitted events or rendered slot content.

Creating reusable composables with VueUse involves extracting component logic into standalone functions using the Composition API. This pattern enables sharing stateful logic across multiple Vue 3 components without duplicating code.

Yes, Vue 3 component guidance explicitly covers prop and emit conventions. It provides reference patterns for defining typed props, handling emit events, and structuring slots to ensure consistent component interfaces across your application.

The Composition API organizes component logic by feature rather than option type, enabling better code reuse through composables. It integrates directly with VueUse and Vitest, streamlining both logic composition and component testing compared to the Options API.

Yes, Vue Test Utils can validate slot implementations in Vue 3. The testing practices covered include mounting components with slot content and asserting that the rendered output correctly reflects the provided slot data.
