Context

In this example, we use Composable Function's context to authorize a specific header.

const schema = z.object({ email: z.string().min(1).email() })

const contextSchema = z.object({
  customHeader: z.string({
    error: (issue) =>
      issue.input == null
        ? 'Missing custom header'
        : 'Invalid custom header',
  }),
})

const mutation = applySchema(
  schema,
  contextSchema,
)(async (values) => values)

export const action = async ({ request }: Route.ActionArgs) => {
  return formAction({
    request,
    schema,
    mutation,
    context: { customHeader: request.headers.get('customHeader') },
  })
}

export default () => <SchemaForm schema={schema} />
