## 🚀 Quick Start

### Installation

```bash
# Using Yarn (recommended)
yarn add @datamonsterr/vdt-dashboard

# Using npm
npm install @datamonsterr/vdt-dashboard

# Using pnpm
pnpm add @datamonsterr/vdt-dashboard
```

### Basic Usage

The simplest way to integrate VDT Dashboard into your app:

```tsx
import { VDTDashboard } from '@datamonsterr/vdt-dashboard'
import '@datamonsterr/vdt-dashboard/styles'

function App() {
  const handleSchemaChange = (data) => {
    console.log('Schema updated:', data.tables)
    console.log('Relationships:', data.foreignKeys)
    // Save to your backend, state management, etc.
  }

  return (
    <div>
      <h1>My Application</h1>
      
      {/* Simple button that opens the schema builder */}
      <VDTDashboard 
        buttonText="Design Database Schema"
        onSchemaChange={handleSchemaChange}
      />
    </div>
  )
}
```

That's it! The button will open a complete database schema builder in a modal dialog.

## 📋 Usage Examples

### 1. Basic Integration with Custom Styling

```tsx
<VDTDashboard 
  buttonText="Database Designer"
  buttonVariant="outline"
  buttonClassName="my-custom-button-class"
  modalSize="xl"
  onSchemaChange={(data) => {
    // Handle schema changes
    saveToDatabase(data)
  }}
/>
```

### 2. With Initial Data

```tsx
import { sampleTables, sampleForeignKeys } from '@datamonsterr/vdt-dashboard'

<VDTDashboard 
  buttonText="Edit Schema"
  initialTables={sampleTables}
  initialForeignKeys={sampleForeignKeys}
  onSchemaChange={handleSchemaChange}
/>
```

### 3. Embedded Canvas (No Modal)

```tsx
import { StandaloneSchemaCanvas } from '@datamonsterr/vdt-dashboard'

function SchemaEditor() {
  return (
    <div className="h-96 border rounded">
      <StandaloneSchemaCanvas 
        showToolbar={true}
        showUndoRedo={true}
        onSchemaChange={handleSchemaChange}
      />
    </div>
  )
}
```

### 4. Authentication Required

```tsx
<VDTDashboard 
  buttonText="Pro Schema Builder"
  requireAuthForSchemaBuilder={true}
  clerkPublishableKey="your-clerk-key"
  onSchemaChange={handleSchemaChange}
/>
```

## 🔐 Authentication

VDT Dashboard includes **managed authentication** powered by Clerk:

### Zero Configuration (Recommended)
```tsx
// Uses VDT's managed authentication - no setup required
<VDTDashboard 
  requireAuthForSchemaBuilder={true}
  onSchemaChange={handleSchemaChange}
/>
```

### Bring Your Own Clerk Instance
```tsx
// Use your existing Clerk setup
<VDTDashboard 
  clerkPublishableKey="pk_test_your-clerk-key"
  requireAuthForSchemaBuilder={true}
  onSchemaChange={handleSchemaChange}
/>
```

### Anonymous Usage
```tsx
// Allow usage without authentication
<VDTDashboard 
  requireAuthForSchemaBuilder={false}
  onSchemaChange={handleSchemaChange}
/>
```

## 🎨 Theming

The dashboard uses isolated CSS to prevent conflicts with your app's styling:

```tsx
<VDTDashboard 
  initialTheme="dark"  // 'light' | 'dark'
  buttonText="Schema Builder"
  // Your app's theme remains completely unaffected
/>
```

The dashboard's theme is managed independently and won't interfere with your application's styling.

## 📝 TypeScript Support

Full TypeScript support with comprehensive type definitions:

```tsx
import type { 
  Table, 
  ForeignKey, 
  Column, 
  SQLDataType,
  SchemaData 
} from '@datamonsterr/vdt-dashboard'

const handleSchemaChange = (data: SchemaData) => {
  // data is fully typed
  data.tables.forEach((table: Table) => {
    console.log(`Table: ${table.name}`)
    table.columns.forEach((column: Column) => {
      console.log(`  ${column.name}: ${column.dataType}`)
    })
  })
  
  data.foreignKeys.forEach((fk: ForeignKey) => {
    console.log(`Relationship: ${fk.sourceTable} -> ${fk.targetTable}`)
  })
}
```

## 🏗️ Advanced Integration

### Custom Component Placement

Place the dashboard button anywhere in your UI:

```tsx
// In a navigation bar
<nav className="flex items-center space-x-4">
  <Link to="/dashboard">Dashboard</Link>
  <Link to="/users">Users</Link>
  <VDTDashboard 
    buttonText="Schema"
    buttonVariant="ghost"
    buttonClassName="text-sm"
  />
</nav>

// In a toolbar
<div className="toolbar">
  <button>Save</button>
  <button>Export</button>
  <VDTDashboard buttonText="Design DB" buttonVariant="outline" />
</div>

// As a card action
<Card>
  <CardHeader>
    <CardTitle>Database Schema</CardTitle>
  </CardHeader>
  <CardContent>
    <p>Design your database schema visually</p>
  </CardContent>
  <CardFooter>
    <VDTDashboard buttonText="Open Designer" />
  </CardFooter>
</Card>
```

### Data Persistence

Integrate with your backend or state management:

```tsx
// With REST API
const handleSchemaChange = async (data: SchemaData) => {
  try {
    await fetch('/api/schemas', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(data)
    })
    toast.success('Schema saved successfully!')
  } catch (error) {
    toast.error('Failed to save schema')
  }
}

// With React Query
const mutation = useMutation({
  mutationFn: (data: SchemaData) => saveSchema(data),
  onSuccess: () => queryClient.invalidateQueries(['schemas'])
})

<VDTDashboard onSchemaChange={mutation.mutate} />

// With Zustand/Redux
const updateSchema = useSchemaStore(state => state.updateSchema)
<VDTDashboard onSchemaChange={updateSchema} />
```

### Error Handling

```tsx
const [error, setError] = useState<string | null>(null)

<VDTDashboard 
  onSchemaChange={(data) => {
    try {
      validateSchema(data)
      saveSchema(data)
      setError(null)
    } catch (err) {
      setError(err.message)
    }
  }}
/>

{error && <div className="error">{error}</div>}
```
