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

Lets form builder authors validate steps with Joi v18. Each step's schema, edited in the builder, compiles with Joi at runtime, and the generated code contains the same Joi code.

Installation

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

Usage

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

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

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

Use the same registry with createFormFromDefinition and generateCode.

Values are validated without type conversion (convert: false), reporting every issue (abortEarly: false). 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 joiSchemaBuilder, made with createSchemaBuilder from the core package, if you want to build on it.
