Vue 3 Composition API best practices involve using <script setup> for concise syntax, applying typed TypeScript, and isolating modular logic into reusable composables to improve component readability and maintainability.

Choosing between ref and reactive in Vue 3 depends on your state structure; use refs for primitives and reactive for objects, while leveraging computed properties and readonly state to enforce reactivity and prevent unintended mutations.

Structure Vue 3 components for SSR readiness by following proper emit naming, prop validation, and provide/inject patterns, and use KeepAlive with dynamic components to cache state and optimize performance during server-side rendering.

Optimize Vue 3 performance by avoiding computed value mutations, ensuring proper key usage in lists, and organizing composition code compactly to prevent unnecessary reactivity triggers and reduce rendering overhead.

Refactor an existing Vue project by auditing major components for <script setup> usage, migrating Options API logic to composables, and integrating reference docs into CI checks to enforce consistent Vue 3 patterns across your team.
