v1.6.0

🆕 New Components

Form

Centralized form validation and submission — full parity with Nuxt UI v4's Form component.

• Schema validation — Zod 3.24+, Valibot 1.0+, Yup 1.7+ (via Standard Schema) and Joi 17+ (dedicated adapter). Pass any schema directly to the schema prop — zero adapters needed
• Custom validate — Sync or async function, runs alongside schema if both provided
• Field-level validation — Triggers on blur / input / change / focus with configurable debounce (validateOnInputDelay) and eager-after-first-blur semantics
• Dirty / touched / blurred tracking — Reactive SvelteSet-based field tracking with dirty, dirtyFields, touchedFields, blurredFields getters
• Loading auto-disable — loadingAuto (default true) flips loading during async submit; double-submit guard via #submitting flag works even with loadingAuto: false
• Nested forms — <Form nested name="address"> attaches to parent; submit() cascades validation, setErrors() / clear() / reset() cascade too. Errors prefixed with child path
• Schema transform output — Zod .transform(), Valibot pipe transforms etc. applied on submit when transform: true
• Full programmatic API via bind:api — submit(), validate(), clear(), reset(), setErrors(), getErrors() + reactive errors, loading, disabled, dirty, submitCount
• Error summary — Read form.errors reactively to render error lists
• 9 interactive demo examples — Basic Zod login, schema lib comparison (Zod/Valibot/Yup/Joi tabs), async submit, programmatic API, async username check, array repeater with nested forms per row, dependent fields (Zod refine), nested address form, error summary + reset

🛠️ New Utilities

• useFormFieldEmit() — Helper hook for custom input components to emit form events (blur, input, change, focus) to the parent Form
• wireFormEvents() — Convenience wrapper that merges emit calls with user-supplied event handlers for custom input wrappers
• FORM_FIELD_CONTEXT_KEY — Exported Symbol for the FormField context (replaces string key)
• getFormContext() — Access the parent Form context from custom components
• InputValue type + InputProps<T extends InputValue> — Generic type for type-safe bind:value inference (string | number | bigint | boolean | null | undefined)

⚡ Changed

• 10 input components (Input, Textarea, Select, SelectMenu, Checkbox, CheckboxGroup, RadioGroup, Switch, PinInput, Slider) — wired up form event emission via useFormFieldEmit. CheckboxGroup and RadioGroup fire focus/blur on the fieldset wrapper. Backward-compatible: no-op when used outside a Form
• FormField — Context key migrated from string 'formField' to exported Symbol FORM_FIELD_CONTEXT_KEY

📦 Dependencies

• Added @standard-schema/spec (runtime dependency, types-only, zero bundle cost)
• Added optional peer dependencies: zod ^3.24.0 || ^4.0.0, valibot ^1.0.0, yup ^1.7.0, joi ^17.0.0 || ^18.0.0 (all optional — user installs whichever they prefer)
• Added zod, valibot, yup, joi as devDependencies (for integration tests + demo)
