vue-composables

Refactoring existing logic into Vue 3 composables involves extracting reusable state and methods into use* functions. Place these functions in src/composables, ensure single responsibility, and separate UI concerns from core logic to improve project maintainability and reduce duplication.

Vue 3 composable naming conventions require prefixing files and functions with use in PascalCase, such as useCounter.ts. Composables must be located under the src/composables directory and export named functions to enforce consistency across the project.

Yes, you can review and validate existing composables across a Vue project. It checks code against established patterns, ensuring proper use prefixing, correct location under src/composables, appropriate error handling, and correct lifecycle usage within the Composition API.

The best way to structure state and methods in a Vue composable is to enforce single responsibility. Expose clear state and methods, separate UI concerns from underlying logic, and apply structured patterns for error handling and lifecycle usage to create high-quality, reusable functions.
