# useInflateView

## Description

A React hook that takes a component type and props and returns a memoized React element. This hook is useful for creating reusable component instances with built-in memoization to prevent unnecessary re-renders when props haven't changed. It's particularly effective in scenarios where you need to create component instances dynamically or repeatedly.

- Component Inflater
- Memoized View Hook
- Dynamic Component Hook

## Hook Signature

```tsx
function useInflateView<T extends Record<string, unknown>>(
  Component: ComponentType<T>,
  props: T
): ReactElement
```

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `Component` | `ComponentType<T>` | Yes | React component to render |
| `props` | `T` | Yes | Props to pass to the component |

## Return Value

Returns a memoized `ReactElement` that will only re-render when the component or props change.

## Examples

### Basic Usage

```tsx
import React, { useState } from 'react';
import { useInflateView, Button, Text } from '@delightui/components';

const UserCard = ({ name, email, age }) => (
  <div style={{ padding: '16px', border: '1px solid #ccc', borderRadius: '8px' }}>
    <Text type="Heading4">{name}</Text>
    <Text type="BodyMedium">{email}</Text>
    <Text type="BodySmall">Age: {age}</Text>
  </div>
);

function BasicExample() {
  const [userData, setUserData] = useState({
    name: 'John Doe',
    email: 'john@example.com',
    age: 30
  });

  // This view will only re-render when userData changes
  const userCardView = useInflateView(UserCard, userData);

  return (
    <div>
      {userCardView}
      
      <Button onClick={() => setUserData(prev => ({
        ...prev,
        age: prev.age + 1
      }))}>
        Increment Age
      </Button>
    </div>
  );
}
```

### Dynamic Component Selection

```tsx
import React, { useState } from 'react';
import { useInflateView, Button, Text } from '@delightui/components';

const SuccessMessage = ({ message }) => (
  <div style={{ color: 'green', padding: '8px' }}>
    ✅ {message}
  </div>
);

const ErrorMessage = ({ message }) => (
  <div style={{ color: 'red', padding: '8px' }}>
    ❌ {message}
  </div>
);

const InfoMessage = ({ message }) => (
  <div style={{ color: 'blue', padding: '8px' }}>
    ℹ️ {message}
  </div>
);

function DynamicExample() {
  const [messageType, setMessageType] = useState('info');
  const [message] = useState('This is a dynamic message');

  const getComponent = () => {
    switch (messageType) {
      case 'success': return SuccessMessage;
      case 'error': return ErrorMessage;
      default: return InfoMessage;
    }
  };

  // Dynamically inflate different components based on type
  const messageView = useInflateView(getComponent(), { message });

  return (
    <div>
      {messageView}
      
      <div style={{ marginTop: '16px', display: 'flex', gap: '8px' }}>
        <Button onClick={() => setMessageType('success')}>
          Success
        </Button>
        <Button onClick={() => setMessageType('error')}>
          Error
        </Button>
        <Button onClick={() => setMessageType('info')}>
          Info
        </Button>
      </div>
    </div>
  );
}
```

### List Rendering with Memoization

```tsx
import React, { useState } from 'react';
import { useInflateView, Button, Text, Card } from '@delightui/components';

const ProductCard = ({ id, name, price, inStock }) => (
  <Card style={{ padding: '16px', margin: '8px 0' }}>
    <Text type="Heading5">{name}</Text>
    <Text type="BodyMedium">${price}</Text>
    <Text type="BodySmall" style={{ 
      color: inStock ? 'green' : 'red' 
    }}>
      {inStock ? 'In Stock' : 'Out of Stock'}
    </Text>
  </Card>
);

function ListExample() {
  const [products] = useState([
    { id: 1, name: 'Laptop', price: 999, inStock: true },
    { id: 2, name: 'Mouse', price: 29, inStock: false },
    { id: 3, name: 'Keyboard', price: 79, inStock: true }
  ]);

  return (
    <div>
      <Text type="Heading3">Product List</Text>
      {products.map(product => {
        // Each product card is memoized individually
        const ProductView = () => useInflateView(ProductCard, product);
        return <ProductView key={product.id} />;
      })}
    </div>
  );
}
```

### Configuration-Based Component

```tsx
import React, { useState } from 'react';
import { useInflateView, Button, Text, Input, Toggle } from '@delightui/components';

const ConfigurableForm = ({ fields, onSubmit }) => (
  <form onSubmit={onSubmit}>
    {fields.map(field => (
      <div key={field.name} style={{ marginBottom: '16px' }}>
        <Text type="BodyMedium">{field.label}</Text>
        {field.type === 'text' && (
          <Input 
            name={field.name}
            placeholder={field.placeholder}
            required={field.required}
          />
        )}
        {field.type === 'toggle' && (
          <Toggle name={field.name}>
            {field.label}
          </Toggle>
        )}
      </div>
    ))}
    <Button actionType="submit">Submit</Button>
  </form>
);

function ConfigurationExample() {
  const [formConfig] = useState({
    fields: [
      {
        name: 'username',
        type: 'text',
        label: 'Username',
        placeholder: 'Enter username',
        required: true
      },
      {
        name: 'email',
        type: 'text',
        label: 'Email',
        placeholder: 'Enter email',
        required: true
      },
      {
        name: 'notifications',
        type: 'toggle',
        label: 'Enable Notifications'
      }
    ]
  });

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log('Form submitted');
  };

  // Form structure is memoized based on configuration
  const formView = useInflateView(ConfigurableForm, {
    ...formConfig,
    onSubmit: handleSubmit
  });

  return (
    <div>
      <Text type="Heading3">Dynamic Form</Text>
      {formView}
    </div>
  );
}
```

### Performance Optimization Example

```tsx
import React, { useState, useCallback } from 'react';
import { useInflateView, Button, Text } from '@delightui/components';

const ExpensiveComponent = ({ data, onProcess }) => {
  // Simulate expensive computation
  const processedData = React.useMemo(() => {
    console.log('Processing data...'); // This should only log when data changes
    return data.map(item => item * 2);
  }, [data]);

  return (
    <div>
      <Text type="Heading4">Processed Results</Text>
      <Text type="BodyMedium">
        Results: {processedData.join(', ')}
      </Text>
      <Button onClick={onProcess}>
        Process Again
      </Button>
    </div>
  );
};

function PerformanceExample() {
  const [data] = useState([1, 2, 3, 4, 5]);
  const [counter, setCounter] = useState(0);

  const handleProcess = useCallback(() => {
    console.log('Process clicked');
  }, []);

  // Component is memoized - won't re-render when counter changes
  const expensiveView = useInflateView(ExpensiveComponent, {
    data,
    onProcess: handleProcess
  });

  return (
    <div>
      <Text type="Heading3">Performance Test</Text>
      <Text type="BodyMedium">Counter: {counter}</Text>
      
      <Button onClick={() => setCounter(c => c + 1)}>
        Increment Counter (won't affect expensive component)
      </Button>
      
      {expensiveView}
    </div>
  );
}
```

### Conditional Component Rendering

```tsx
import React, { useState } from 'react';
import { useInflateView, Button, Text, Spinner } from '@delightui/components';

const LoadingView = ({ message }) => (
  <div style={{ textAlign: 'center', padding: '40px' }}>
    <Spinner />
    <Text type="BodyMedium" style={{ marginTop: '16px' }}>
      {message}
    </Text>
  </div>
);

const ContentView = ({ title, content }) => (
  <div>
    <Text type="Heading3">{title}</Text>
    <Text type="BodyMedium">{content}</Text>
  </div>
);

const ErrorView = ({ error, onRetry }) => (
  <div style={{ textAlign: 'center', padding: '40px' }}>
    <Text type="Heading4" style={{ color: 'red' }}>
      Error Occurred
    </Text>
    <Text type="BodyMedium">{error}</Text>
    <Button onClick={onRetry} style={{ marginTop: '16px' }}>
      Retry
    </Button>
  </div>
);

function ConditionalExample() {
  const [state, setState] = useState('loading'); // loading, success, error
  const [data, setData] = useState(null);

  const loadData = () => {
    setState('loading');
    setTimeout(() => {
      if (Math.random() > 0.3) {
        setData({
          title: 'Success!',
          content: 'Data loaded successfully.'
        });
        setState('success');
      } else {
        setState('error');
      }
    }, 2000);
  };

  const getView = () => {
    switch (state) {
      case 'loading':
        return useInflateView(LoadingView, {
          message: 'Loading data...'
        });
      case 'success':
        return useInflateView(ContentView, data);
      case 'error':
        return useInflateView(ErrorView, {
          error: 'Failed to load data',
          onRetry: loadData
        });
      default:
        return null;
    }
  };

  return (
    <div>
      <Button onClick={loadData}>
        Load Data
      </Button>
      <div style={{ marginTop: '20px' }}>
        {getView()}
      </div>
    </div>
  );
}
```

## Performance Benefits

1. **Memoization**: Component instances are memoized based on props, preventing unnecessary re-renders
2. **Efficient Dependency Tracking**: Only re-renders when component or props actually change
3. **Memory Optimization**: Reuses component instances when props are unchanged
4. **Computation Reduction**: Reduces the overhead of recreating React elements

## Best Practices

1. **Stable References**: Use stable component references to maximize memoization benefits
2. **Prop Optimization**: Keep props objects shallow when possible for better comparison
3. **Callback Memoization**: Use `useCallback` for function props to maintain memoization
4. **Avoid Inline Objects**: Don't create new objects in props unless necessary

## Common Patterns

### Configuration-Driven UI
```tsx
const configBasedView = useInflateView(DynamicForm, formConfiguration);
```

### Conditional Rendering
```tsx
const conditionalView = useInflateView(
  isLoading ? LoadingSpinner : ContentComponent, 
  componentProps
);
```

## TypeScript Support

The hook is fully typed and provides excellent TypeScript support:

```tsx
interface MyComponentProps {
  title: string;
  count: number;
  onAction: (value: string) => void;
}

const MyComponent: React.FC<MyComponentProps> = ({ title, count, onAction }) => {
  // Component implementation
};

// TypeScript will enforce correct prop types
const view = useInflateView(MyComponent, {
  title: "Required string",     // ✅ Required
  count: 42,                   // ✅ Required number
  onAction: (val) => {...}     // ✅ Required function
  // Missing any required prop will cause TypeScript error
});
```
