To create composables in Vue 3, use the Composition API to extract reactive state and methods into reusable functions. This pattern manages shared logic efficiently, ensuring components remain maintainable and logic is easily imported across your application.

You can test Vue components with Vitest by writing unit tests that mount components and assert their behavior. This Skill provides testing strategies to validate component rendering, interactions, and composable outputs effectively within your development workflow.

The best way to define props and emits in Vue 3 is using the Composition API's type-safe patterns. This Skill covers implementing props, emits, and slots correctly, ensuring reusable components communicate effectively and maintain strict TypeScript integration.

You integrate TypeScript with Vue 3 components by applying Composition API patterns that enforce type safety. This Skill guides you through defining typed props, emits, and composables, ensuring robust and maintainable application code.

The defineModel macro in Vue 3 simplifies two-way binding by creating a reactive reference that automatically syncs with a parent component's v-model. This Skill explains implementing defineModel correctly for reusable and type-safe components.

Vue 3 reactivity breaks when you fail to follow mutation patterns or lose proxy references. This Skill addresses common pitfalls in reactivity management and provides Composition API best practices to ensure state updates correctly.
