@jfdevelops/multi-step-form-builder-arktype

Lets form builder authors validate steps with ArkType v2. Each step's schema, edited in the builder, compiles with ArkType at runtime, and the generated code contains the same ArkType code.

Installation

pnpm add @jfdevelops/multi-step-form-builder-core @jfdevelops/multi-step-form-builder-arktype arktype

Usage

import { createFormBuilder, createRegistry } from '@jfdevelops/multi-step-form-builder-core';
import { arktypeAdapter } from '@jfdevelops/multi-step-form-builder-arktype';

const registry = createRegistry({ validators: [arktypeAdapter] });
const builder = createFormBuilder({ registry });

// Every step, unless a step picks its own library…
builder.settings.update({ validator: 'arktype' });
// …or just one step.
builder.validation.set(builder.getSnapshot().activeStepId!, { kind: 'schema', library: 'arktype' });

Use the same registry with createFormFromDefinition and generateCode.

Checks use narrow so the builder’s messages are kept. ArkType reports the first failing check of each value. The adapter runs the same conformance suite as every other adapter, so a step behaves the same whichever library compiles it: the same fields fail, with the builder's messages.

The schema description is exported as arktypeSchemaBuilder, made with createSchemaBuilder from the core package, if you want to build on it.
