The rest of this page reuses one set of Form Wire examples.

Swapping the mapper changes the UI library. The schemas, actions, field names, conditional sections, and wizard composition stay the same.

01 / Simple contact formsource

One schema creates a complete accessible form with validation, defaults, and an action.

const Contact = createFormWire(
  z.object({
    name: z.string().min(2),
    email: z.email(),
    message: z.string().min(10),
  }),
  {
    fields: {
      message: { component: "textarea" },
    },
  },
)

<Contact.Form action={saveContact} />

02 / Common field coveragesource

Text, number, date, select, checkbox, textarea, submit state, and form messages use the same mapper.

const Quote = createFormWire(
  z.object({
    company: z.string().min(2),
    plan: z.enum(["starter", "team", "enterprise"]),
    seats: z.coerce.number().min(1),
    launchDate: z.coerce.date(),
    needsSecurityReview: z.boolean(),
    notes: z.string().optional(),
  })
)

<Quote.Form action={requestQuote} />

03 / Conditional compositionsource

Use generated fields directly when you need custom flow without giving up schema inference.

<Onboarding.Form
  action={submitOnboarding}
  validationTiming="onChange"
>
  <Onboarding.Fields names={["projectName", "projectType"]} />
  <Onboarding.When field="projectType" equals="customer">
    <Onboarding.Field name="customerEmail" />
  </Onboarding.When>
  <Onboarding.Fields names={["budget", "approved"]} />
</Onboarding.Form>

04 / Multi-step wizardsource

Wizard steps share the same action and schema while Form Wire handles per-step rendering.

<WorkspaceWizard.Wizard
  action={launchWorkspace}
  nextLabel="Next step"
  previousLabel="Back"
>
  <WorkspaceWizard.Step title="Basics">
    <WorkspaceWizard.Fields names={["workspace", "ownerEmail"]} />
  </WorkspaceWizard.Step>
  <WorkspaceWizard.Step title="Plan">
    <WorkspaceWizard.Fields names={["tier", "timeline"]} />
  </WorkspaceWizard.Step>
</WorkspaceWizard.Wizard>
