vue-composables

To create reusable logic in Vue 3, you extract reactive state and lifecycle hooks into a standalone composable function using the Composition API. This encapsulates complex component logic for cleaner, more maintainable Vue components.

In Vue composables, `ref` provides reactive state for primitive values, while `reactive` handles reactive state for objects. Both manage reactivity in the Composition API, but `ref` requires `.value` for access.

You should use Vue composables when you need organized, type-safe reusable logic. Composables leverage the Vue 3 Composition API to avoid mixin naming conflicts and make data flow explicit in your components.

Yes, you can use lifecycle hooks and watchers inside a Vue composable. The Composition API allows functions like `onMounted` and `watch` to be called within composables to manage side effects and reactive dependencies.

You can manage form state and validation logic by moving reactive data, watchers, and submission functions into a custom composable. This separates complex form logic from your Vue components, making them cleaner and easier to test.

Yes, dependency injection works with Vue 3 composables. You can use Composition API functions like `provide` and `inject` within your composables to share reactive state and logic across your application components.
