form-objects

Form objects solve scattered logic by encapsulating multi-step form validation and data transformation in a dedicated pattern. They decouple complex form state from domain entities using typed structures and Zod schemas.

Form objects provide reusable patterns for transforming nested form input into domain entities ready for persistence. This approach manages complex form state and data mapping cleanly within TypeScript projects.

Yes, you can use Zod to define typed step schemas within form objects. This pattern satisfies requirements for typed validation schemas and data transformation utilities when managing multi-step forms.

The Rails form object pattern works with TypeScript and Next.js by adapting its decoupled validation logic into typed structures. It manages state, error reporting, and step navigation without tying form logic to domain entities.

You need a form object when handling complex validation scenarios, multi-step forms, or form-to-entity mapping. It prevents scattered form logic by decoupling validation and data transformation from domain entities.
