XE TLDraw Window Manager - Improvement Plan

🎯 Goal

Transform this into a world-class, production-ready window management library that developers love to use.

📁 Project Structure Improvements

1. Separate Library and Examples

xe-tldraw-window-manager/
├── packages/
│   ├── core/                 # Core library
│   │   ├── src/
│   │   ├── tests/
│   │   └── package.json
│   ├── themes/              # Theme packages
│   │   ├── default/
│   │   ├── macos/
│   │   └── windows11/
│   └── examples/            # Example applications
│       ├── basic/
│       ├── advanced/
│       └── playground/
├── docs/                    # Documentation
├── scripts/                 # Build scripts
└── package.json            # Root package.json

2. Add Missing Files

• LICENSE (MIT)
• .npmignore
• CHANGELOG.md
• CONTRIBUTING.md
• .github/ workflows
• tsconfig.build.json (optimized for builds)

🧪 Testing Infrastructure

1. Unit Tests (Vitest)

// src/lib/shapes/__tests__/WindowShape.test.tsx
describe('WindowShape', () => {
  it('renders with default props', () => {})
  it('handles minimize correctly', () => {})
  it('handles maximize correctly', () => {})
  it('handles close correctly', () => {})
})

2. Integration Tests

// src/lib/__tests__/integration.test.tsx
describe('Window Manager Integration', () => {
  it('manages multiple windows correctly', () => {})
  it('handles z-index stacking', () => {})
  it('persists window state', () => {})
})

3. Visual Tests (Playwright)

• Screenshot comparisons for themes
• Animation smoothness tests
• Cross-browser rendering

♿ Accessibility Improvements

1. ARIA Support

<div
  role="dialog"
  aria-label={props.title}
  aria-modal={isActive}
  aria-describedby={`${id}-content`}
  tabIndex={0}
>

2. Keyboard Navigation

• Tab - Navigate between windows
• Alt+Tab - Window switcher
• Escape - Close active window
• Arrow keys - Move windows
• Shift+Arrow - Resize windows

3. Screen Reader Support

• Announce window operations
• Provide context for window state
• Descriptive button labels

🚀 Performance Optimizations

1. Style Extraction

// styles/WindowShape.module.css
.windowContainer {
  /* Move all inline styles here */
}

// Or use CSS-in-JS with emotion/styled-components
const WindowContainer = styled.div`
  /* Styles here */
`;

2. Memoization

const WindowShape = React.memo(({ shape, theme }) => {
  const styles = useMemo(() => 
    calculateStyles(theme), [theme]
  );
  // ...
});

3. Virtual Scrolling

For handling 100+ windows efficiently

🎨 Enhanced Features

1. Window Snapping

interface SnapConfig {
  enabled: boolean;
  threshold: number;
  showGuides: boolean;
  snapToGrid: boolean;
  gridSize: number;
}

2. Animation System

interface AnimationConfig {
  duration: number;
  easing: 'linear' | 'ease-in' | 'ease-out' | 'spring';
  reducedMotion: boolean;
}

3. Window Events

interface WindowEvents {
  onBeforeClose?: (e: WindowCloseEvent) => void | boolean;
  onClose?: (id: string) => void;
  onMinimize?: (id: string) => void;
  onMaximize?: (id: string) => void;
  onRestore?: (id: string) => void;
  onFocus?: (id: string) => void;
  onBlur?: (id: string) => void;
  onResize?: (id: string, size: Size) => void;
  onMove?: (id: string, position: Position) => void;
}

4. Content Framework

interface WindowContent {
  type: 'react' | 'iframe' | 'custom';
  component?: React.ComponentType;
  url?: string;
  props?: Record<string, any>;
  sandbox?: boolean;
}

5. State Persistence

interface PersistenceAdapter {
  save(state: WindowManagerState): Promise<void>;
  load(): Promise<WindowManagerState>;
  clear(): Promise<void>;
}

// Built-in adapters
class LocalStorageAdapter implements PersistenceAdapter {}
class IndexedDBAdapter implements PersistenceAdapter {}

📚 Documentation Improvements

🔌 Plugin System

interface WindowManagerPlugin {
  name: string;
  version: string;
  install(wm: WindowManager): void;
}

// Example plugins
class WindowSnapPlugin implements WindowManagerPlugin {}
class WindowEffectsPlugin implements WindowManagerPlugin {}
class WindowShortcutsPlugin implements WindowManagerPlugin {}
