Vue 3's Composition API uses ref() and reactive() to create reactive state. ref() wraps primitive values, reactive() handles objects. Both trigger component re-renders when state changes, enabling predictable data flow for SPAs and PWAs without Options API boilerplate.

Combine Vue Router for page navigation with centralized state management via composables or a store. This pattern keeps route-driven state synchronized and simplifies data fetching on navigation, essential for scalable single-page applications.

Use computed properties instead of methods for cached, reactive derived values. Implement lazy loading for routes and components to reduce initial bundle size. These patterns prevent unnecessary re-renders and improve SPA responsiveness.

Yes. Composition API coexists with Options API in Vue 3, allowing gradual migration. Refactor data, methods, and lifecycle hooks into composable functions that return reactive state and handlers, modernizing codebases incrementally.

Extract shared stateful logic into composable functions that return reactive data and methods. Composables enable code reuse across components without prop drilling, supporting shared patterns for forms, data fetching, and lifecycle management.

Yes. Vue 3 with Composition API has first-class TypeScript support. Type reactive state with ref<T>() and reactive<T>(), define composable return types, and leverage full IDE autocomplete and type checking in single-file components.
