## What is Object UI?

Object UI is a **modern, lightweight, schema-driven UI engine** that transforms JSON configurations into beautiful, performant React interfaces. Build enterprise-grade applications without writing repetitive UI code.

```json
{
"type": "form",
"title": "Contact Us",
"body": [
{ "type": "input", "name": "email", "label": "Your Email", "required": true },
{ "type": "textarea", "name": "message", "label": "Message" }
],
"actions": [
{ "type": "submit", "label": "Send Message", "level": "primary" }
]
}
```

That's it! This JSON creates a complete, accessible, and beautiful form.

## ✨ Features

## Why Object UI?

### For You as a Developer

**Stop Writing Repetitive UI Code**
```tsx
// Traditional React: 200+ lines
function UserForm() {
// ... useState, validation, handlers, JSX
}

// Object UI: 20 lines
const schema = {
type: "crud",
api: "/api/users",
columns: [...]
}
```

**Better Performance, Smaller Bundle**
- Automatic code splitting
- Lazy-loaded components
- Zero runtime CSS overhead
- Optimized for production

**Full Control & Flexibility**
- Mix with existing React code
- Override any component
- Custom themes with Tailwind
- Export to standard React anytime

## Quick Start

### Installation

```bash
# Using npm
npm install @object-ui/react @object-ui/components

yarn add @object-ui/react @object-ui/components

# Using pnpm
pnpm add @object-ui/react @object-ui/components
```

### Basic Usage

```tsx
import React from 'react'
import { SchemaRenderer } from '@object-ui/react'
import { registerDefaultRenderers } from '@object-ui/components'

// Register default components once
registerDefaultRenderers()

const schema = {
type: "page",
title: "Dashboard",
body: {
type: "grid",
columns: 3,
items: [
{ type: "card", title: "Total Users", value: "${stats.users}" },
{ type: "card", title: "Revenue", value: "${stats.revenue}" },
{ type: "card", title: "Orders", value: "${stats.orders}" }
]
}
}

function App() {
const data = {
stats: { users: 1234, revenue: "$56,789", orders: 432 }
}

return <SchemaRenderer schema={schema} data={data} />
}

export default App
```
