wizzard-stepper-react 🧙‍♂️

A flexible, headless, and strictly typed multi-step wizard library for React. Built with adapter patterns in mind to support any form library (React Hook Form, Formik, etc.) and any validation schema (Zod, Yup).

---

🚀 Quick Start (v2.0.0 Modern)

Version 2.0.0 introduces the Factory Pattern, providing 100% type safety and optimized performance out of the box.

1. Create your Wizard Kit

Define your data schema and generate typed hooks.

// wizards/auth-wizard.ts
import { createWizardFactory } from 'wizzard-stepper-react';

interface AuthSchema {
  email: string;
  preferences: { theme: 'light' | 'dark' };
}

export const { 
  WizardProvider, 
  useWizard, 
  useWizardValue, 
  useWizardActions 
} = createWizardFactory<AuthSchema>();

2. Wrap your App

import { WizardProvider } from './wizards/auth-wizard';

const App = () => (
  <WizardProvider>
    <MyWizardComponents />
  </WizardProvider>
);

3. Use Granular Hooks

import { useWizardValue, useWizardActions } from './wizards/auth-wizard';

const EmailInput = () => {
  // ⚡ Atomic re-render: component only updates if 'email' changes
  const email = useWizardValue('email');
  const { setData } = useWizardActions();

  return <input value={email} onChange={e => setData('email', e.target.value)} />;
};

✨ Key Features

• 🧠 Headless Architecture: Full control over UI. You bring the components, we provide the logic.
• 💅 Modern First: Optimized for React 18 with selective rendering and external state store.
• 🔌 Adapter Pattern: Zero-dependency adapters for Zod, Yup validation.
• 🏗️ Complex Data: Built-in support for nested objects using dot notation (user.address.zip).
• 💾 Advanced Persistence: Auto-save to LocalStorage, SessionStorage, or Custom API adapters.
• 🛠️ Developer Tools: High-performance debugging overlay and Redux DevTools integration.

🏗️ Core Concepts

Validation Adapters

We are library-agnostic. Use our pre-built adapters or write your own.

import { ZodAdapter } from 'wizzard-stepper-react';
import { z } from 'zod';

const schema = z.object({ age: z.number().min(18) });
const adapter = new ZodAdapter(schema);

// In your config:
const step = { id: 'age', validationAdapter: adapter };

Navigation Lifecycle

1. Validation: Current step is checked. Navigation stops if invalid.
2. Resolution: Next step conditions (dynamic branching) are evaluated.
3. Guards: beforeLeave hooks run (e.g., for "Unsaved Changes" modals).
4. Commit: State updates and navigation completes.

💾 State Persistence

Isolate your wizard data to prevent collisions when using multiple instances.

import { LocalStorageAdapter } from 'wizzard-stepper-react';

const config = {
  persistence: {
    // 🛡️ Always use a unique prefix for isolation
    adapter: new LocalStorageAdapter('auth_wizard_v2'),
    mode: 'onStepChange' 
  }
};

🛠️ Performance Tuning

Hook	Returns	Re-renders	Best For
useWizardActions	Navigation/Setters	Zero	Buttons, Handlers
useWizardValue	Specific Field	Atomic	Inputs, Labels
useWizardState	UI Meta (Progress)	Minimal	Progress Bars
useWizard	Everything	Full	Orchestration

---

⚠️ Legacy Support (v1.x)

If you are maintaining an older project, you can still use the classic Context-based provider. Note that this mode does not support the new performance-optimized hooks.

import { WizardProvider, useWizard } from 'wizzard-stepper-react';

const OldApp = () => (
  <WizardProvider>
    <MyComponents />
  </WizardProvider>
);
