Feature Requests

Support more than just basic string/number/boolean fields: Union types → select or radio options Array types → multi-select or repeatable sections Nested objects → nested fieldsets Fallback messages when a type isn’t supported yet, so you know what failed.

Allow rules like: requiredWhen (make a field required if another field has a value) exactlyOneOf (mutually exclusive fields) endDate > startDate with timezone support Group-level validations (sum of percentages = 100%)

Support async checks while typing or on blur: Username/email availability Address validation VAT/TIN checks Debounce & caching for better UX Option for “soft-pass” (allow submit until server confirms)

Map backend errors automatically to form fields: Import OpenAPI / JSON Schema or provide an example error shape Automatically match errors to fields Display error messages inline without extra boilerplate This would save time debugging validation responses. Vote if you’d use it!

Let devs configure per-field transforms: Trim/Lowercase/Uppercase Normalizers (e.g., card number spacing) Default values pulled from other fields ( defaultFrom ) VisibleWhen/DisabledWhen logic Wizard step grouping + autosave Would this cover your advanced use cases?
