v0.3.1

Breaking

• FormSchema type renamed to FormDefinition. validateSchema() renamed to validateDefinition().
• FormRenderer prop schema renamed to definition (React and Vue).

@formhaus/core

• New onStepValidate option runs an async validator between steps. nextStepAsync() awaits it. Exposes stepValidating and the StepValidateFn type.

@formhaus/react

• FormRenderer accepts onStepValidate. Continue button shows a loading state while the validator runs.

@formhaus/vue

• FormRenderer accepts onStepValidate. useFormEngine now returns stepValidating.

Packaging

• Breaking: ESM-only. Dropped legacy main and module fields. Minimum Node is 18.
• Fixed @formhaus/vue type resolution under moduleResolution: "node16" and "nodenext".
• @formhaus/core and @formhaus/react down to 2.87 KB and 3.15 KB gzipped.
• sideEffects: false on core, react, and vue.

v0.3.0

Highlights

All packages unified at 0.3.0.

Core

• FieldType accepts any string (built-ins get autocomplete via DefaultFieldType)
• Multiselect validation: minLength/maxLength check selection count, messages say "items" not "characters"
• setErrors() replaces previous errors instead of merging
• validateSchema() detects duplicate field keys and invalid regex patterns
• Cascade clearing respects step-level visibility
• Getter caching for visibleSteps, visibleFields, currentStep, canGoNext

React

• Breaking: CSS class fh-form-actions__btn renamed to fh-form-actions__button
• Breaking: CheckboxField, RadioField, SwitchField structure aligned with Vue
• New MultiselectField (checkbox group)
• optionsProviders prop for dynamic options via optionsFrom
• onAnalyticsEvent prop (focus, blur, error, step change, submit)
• useFormEngine recreates engine on schema.id change
• useFieldOptions handles rejected async providers, avoids redundant calls

Vue

• Breaking: All scoped styles removed (unstyled by default, matching React)
• New MultiselectField (checkbox group)
• optionsProviders, analyticsEvent emit, focus emit on fields
• useFormEngine accepts getter, recreates engine on schema.id change
• useFieldOptions handles rejected async providers, avoids redundant calls

Other

• GitHub Actions CI pipeline
• React and Vue adapter tests (vitest + testing-library)
• Removed unused @vue/test-utils dependency
