# React in Obsidian Patterns

## 1. React Component File (.tsx)
```typescript
import * as React from 'react';
import { useState, useEffect } from 'react';

interface MyComponentProps {
  data: string;
  onUpdate: (value: string) => void;
}

export const MyComponent: React.FC<MyComponentProps> = ({ data, onUpdate }) => {
  const [value, setValue] = useState(data);

  return (
    <div className="my-component">
      <input
        value={value}
        onChange={(e) => {
          setValue(e.target.value);
          onUpdate(e.target.value);
        }}
      />
    </div>
  );
};
```

## 2. ItemView Integration
```typescript
import { ItemView, WorkspaceLeaf } from 'obsidian';
import * as React from 'react';
import { createRoot, Root } from 'react-dom/client';
import { MyComponent } from './MyComponent';

export const VIEW_TYPE = 'my-view';

export class MyReactView extends ItemView {
  root: Root | null = null;

  constructor(leaf: WorkspaceLeaf) {
    super(leaf);
  }

  getViewType() {
    return VIEW_TYPE;
  }

  getDisplayText() {
    return 'My View';
  }

  async onOpen() {
    const container = this.containerEl.children[1];
    container.empty();
    container.addClass('my-view-container');

    this.root = createRoot(container);
    this.root.render(
      <MyComponent
        data="initial"
        onUpdate={(value) => console.log(value)}
      />
    );
  }

  async onClose() {
    this.root?.unmount();
  }
}
```

## 3. Modal Integration
```typescript
import { App, Modal } from 'obsidian';
import * as React from
