Octane-native bindings for Formisch.

This package targets Formisch 1.0.0-rc.0 and vendors its framework-selected core and modular methods at commit 4c494fd8cf105efd04a4b179e9c090595a0bf041. It does not require React at runtime or in its public types.

Formisch's core and method packages are workspace internals rather than independently installable npm dependencies. The published @formisch/react package is used only as a development-time differential oracle.

The adapter preserves Formisch's programmatic onChange and validation-mode names. Native text controls use onInput; selects, checkboxes, and radios use native onChange.

npm install @octanejs/formisch valibot
pnpm add @octanejs/formisch valibot

import { Form, useField, useForm } from '@octanejs/formisch';
import * as v from 'valibot';

const schema = v.object({
	email: v.pipe(v.string(), v.email('Enter a valid email')),
});

function EmailForm() @{
	const form = useForm({ schema, validate: 'input' });
	const email = useField(form, { path: ['email'] });

	<Form of={form} onSubmit={async (output, event) => {
		console.log(output.email, event);
	}}>
		<input
			name={email.props.name}
			ref={email.props.ref}
			value={email.input as string}
			onInput={email.props.onInput}
			onBlur={email.props.onBlur}
		/>
		@if (email.errors) {
			<p>{email.errors[0]}</p>
		}
		<button type="submit">Submit</button>
	</Form>
}

useField also exposes props.onChange for native select, checkbox, and radio controls. Its programmatic field.onChange(value) callback keeps Formisch's upstream name and triggers input/change validation.

All Formisch modular methods—including getInput, setInput, validate, handleSubmit, reset, and field-array operations—are exported from the package root.

• Upstream: @formisch/[email protected]
• Valibot: ^1.4.1
• Octane: exact workspace peer during development
• React and React types: development-only differential oracle; neither is a runtime or public-type dependency
