createAutoForm()

createAutoForm(config) creates a pre-configured <AutoForm> component that bakes in your design system's components, layout slots, class names, and other defaults. Consumer code only needs to supply form, onSubmit, and any per-instance overrides.

import { createAutoForm } from '@uniform-ts/core'

export const MyForm = createAutoForm({
  components: myRegistry,
  layout: { formWrapper: MyCard, submitButton: MyPrimaryButton },
  classNames: { form: 'space-y-6', fieldWrapper: 'flex flex-col gap-1' },
})

Then in any feature:

<MyForm form={userForm} onSubmit={handleSubmit} />

AutoFormConfig options

Option	Type	Description
components	ComponentRegistry	Base component registry (merged with defaultRegistry)
fieldWrapper	React.ComponentType<FieldWrapperProps>	Default field wrapper component
layout	LayoutSlots	Default layout slots (formWrapper, sectionWrapper, submitButton, arrayRowLayout, loadingFallback). Use null for omittable slots (submit/array buttons).
classNames	FormClassNames	Default CSS class names
disabled	boolean	When true, all fields in every form instance are disabled by default
messages	ValidationMessages	Default validation messages
coercions	CoercionMap	Default per-field coercions
labels	FormLabels	Default UI labels (submit, array buttons, aria labels). Import a locale pack from @uniform-ts/core/locales/{en,he,es} to set all strings at once

Merge behaviour

Per-instance props are shallow-merged on top of config defaults. This means any prop you pass at the call site wins. components registries are deep-merged using mergeRegistries, so you can override one field type without replacing the whole registry.

Live Example

A design-system form where every text input has a blue left border and every field wrapper has a bottom line:

Live Editor

const inputStyle = {
  borderLeft: '3px solid #4F46E5',
  paddingLeft: 8,
  borderTop: 'none',
  borderRight: 'none',
  borderBottom: '1px solid var(--ifm-color-emphasis-300)',
  outline: 'none',
  width: '100%',
  fontSize: 14,
  padding: '6px 8px',
}

const wrapperStyle = {
  borderBottom: '1px solid var(--ifm-color-emphasis-200)',
  paddingBottom: 12,
  marginBottom: 12,
}

const CustomInput = ({ value, onChange, onBlur, ref, placeholder, error }) => (
  <div style={wrapperStyle}>
    <input
      ref={ref}
      value={String(value ?? '')}
      onChange={(e) => onChange(e.target.value)}
      onBlur={onBlur}
      style={inputStyle}
      placeholder={placeholder}
    />
    {error && (
      <span style={{ color: 'var(--ifm-color-danger)', fontSize: 12 }}>
        {error}
      </span>
    )}
  </div>
)

const BrandedForm = createAutoForm({
  components: { string: CustomInput },
  labels: { submit: 'Save Changes' },
})

const schema = z.object({
  username: z.string().min(3),
  bio: z.string().optional(),
})

const profileForm = createForm(schema)

function App() {
  const [saved, setSaved] = React.useState(false)
  return (
    <div style={{ fontFamily: 'system-ui', maxWidth: 380 }}>
      {saved && <p style={{ color: 'var(--ifm-color-success)' }}>Saved!</p>}
      <BrandedForm
        form={profileForm}
        fields={{
          username: { label: 'Username' },
          bio: { label: 'Short bio' },
        }}
        onSubmit={() => setSaved(true)}
      />
    </div>
  )
}

render(<App />)
