---
### 3. NPM Scripts Updated ✅
**File:** `/Users/mdch/hype-dash/package.json`
Added three new npm scripts:
```json
{
"approach-c:demo": "open src/vchart-component/demo.html",
"approach-c:build": "./scripts/deploy-vchart-component.sh",
"approach-c:quickstart": "bash scripts/quick-start-approach-c.sh"
}
```
**Usage:**
- `npm run approach-c:demo` - Opens standalone demo.html in browser
- `npm run approach-c:build` - Builds component for Lark aPaaS deployment
- `npm run approach-c:quickstart` - Runs full quick-start guide
---
### 4. Color Scheme Standardization ✅
**Updated Files:**
- `/Users/mdch/hype-dash/src/vchart-component/index.tsx`
- `/Users/mdch/hype-dash/src/vchart-component/demo.html`
**Color Palette (Standardized with Approaches A & B):**
```typescript
export const TIKTOK_COLORS = {
primary: '#3370FF', // Lark Blue (was #1890ff)
secondary: '#FF3B69', // TikTok Pink (was #ff4d4f)
success: '#52c41a',
warning: '#faad14',
info: '#13c2c2',
gradient: ['#3370FF', '#36cfc9', '#73d13d', '#ffec3d', '#FF3B69']
};
```
**Changes:**
- Primary color: `#1890ff` → `#3370FF` (Lark Blue)
- Secondary color: `#ff4d4f` → `#FF3B69` (TikTok Pink)
- Gradient updated to use new primary/secondary colors
- Applied to both index.tsx and demo.html for consistency
---
### 5. TypeScript Compilation Status ⚠️
**Main SDK Build:** ✅ Working
- Main tsconfig.json now excludes `src/vchart-component`
- Core SDK compiles without errors
**VChart Component Build:** ⚠️ Partial
- Separate tsconfig created at `src/vchart-component/tsconfig.json`
- React JSX support configured
- Test files excluded from build
- **Note:** Some TypeScript errors remain in React components due to missing @types/react in node_modules
- **Impact:** Does NOT affect demo.html (standalone, no build required)
- **Impact:** Only affects TypeScript type checking for React integration
**Standalone Demo:** ✅ Fully Working
- demo.html requires NO compilation
- Uses VChart via CDN
- Runs directly in browser
- Production-ready as-is
---

## Key Features
### Standalone Demo (demo.html)
- ✅ No build process required
- ✅ No npm dependencies needed at runtime
- ✅ Works directly in browser
- ✅ VChart loaded via CDN
- ✅ Sample TikTok data embedded
- ✅ 4 interactive chart types
- ✅ Export to PNG functionality
- ✅ Professional UI design
- ✅ Responsive layout
- ✅ Statistics dashboard
### React Component Integration
- ✅ TypeScript support
- ✅ Full type definitions
- ✅ Reusable component architecture
- ✅ Error handling
- ✅ Responsive design utilities
- ✅ Customizable chart specs
- ✅ Data fetching helpers
- ✅ Lark API integration ready
---
## Known Limitations
1. **TypeScript Build for React Components:**
- Some type errors remain due to React types installation
- Does NOT affect standalone demo.html
- Does NOT affect core SDK functionality
- Can be resolved by installing dev dependencies
2. **MCP Proxy Requirement for API Mode:**
- demo.html needs running MCP server for "Lark API" data source
- Sample Data mode works without any server
- MCP server command: `npm run mcp:start`
