vue-composables

Reusable Vue 3 composables encapsulate reactive state, computed values, and methods in a single function, exposing readonly refs to prevent unintended mutations. This pattern enables state logic to be extracted and shared across components without duplication.

Use a withLoadingState helper within composables to centralize async handling, tracking loading and error states alongside API calls. This standardized pattern prevents scattered try-catch logic and ensures consistent error handling across components.

Yes. Composables pair with Pinia stores for clean architecture—composables can dispatch store actions and subscribe to store state, keeping component logic modular while maintaining a single source of truth for global data.

Structure composables with explicit state refs, computed values, and methods, then expose only necessary properties as readonly. This isolation makes unit testing straightforward and enables TypeScript to infer strong types automatically.

Composables integrate Vue lifecycle hooks directly—onMounted, onUnmounted, and others can be called inside the composable function. This keeps lifecycle logic co-located with state, improving readability and reducing component boilerplate.

Composables eliminate code fragmentation across Options API sections, group related logic together, and enable composition over inheritance. This reduces cognitive load and makes large features easier to maintain and refactor.
