## What's Included in Each Example
|
||||
|
||||
### Structure
|
||||
- **Complete file tree** - Every file that gets created
|
||||
- **Configuration files** - Package management, tooling, deployment
|
||||
- **Source code** - Production-ready starting point
|
||||

|
||||
|
||||
## Grey Haven Conventions Applied
|
||||
|
||||
### Naming
|
||||
- Components: `PascalCase` (Button, UserProfile)
|
||||
- Files: `kebab-case` for routes, `PascalCase` for components
|
||||
- Variables: `camelCase` (userId, isActive)
|
||||
- Constants: `UPPER_SNAKE_CASE` (API_URL, MAX_RETRIES)
|
||||
- Database: `snake_case` (user_profiles, api_keys)
|
||||
|
||||
### Structure
|
||||
```
|
||||
src/
|
||||
├── routes/ # API endpoints or page routes
|
||||
├── components/ # Reusable UI components
|
||||
├── services/ # Business logic
|
||||
├── utils/ # Pure helper functions
|
||||
└── types/ # TypeScript type definitions
|
||||
|
||||
tests/ # Mirror src/ structure
|
||||
├── routes/
|
||||
├── components/
|
||||
└── services/
|
||||
```
|
||||
|
||||
### Dependencies
|
||||
- **Package Manager**: npm (Node.js), uv (Python)
|
||||
- **Frontend**: Vite + React + TypeScript + TanStack
|
||||
- **Backend**: Cloudflare Workers + Hono
|
||||
- **Database**: PlanetScale PostgreSQL
|
||||
- **Testing**: Vitest (TS), pytest (Python)
|
||||
- **Validation**: Zod (TS), Pydantic (Python)
|
||||

||||
## Metrics
|
||||
|
||||
### Scaffold Generation Speed
|
||||
|
||||
| Scaffold | Files Created | LOC | Time |
|
||||
|----------|--------------|-----|------|
|
||||
| Cloudflare Worker | 18 | ~450 | 15 min |
|
||||
| React Component | 6 | ~120 | 5 min |
|
||||
| Python API | 22 | ~600 | 20 min |
|
||||
| Full-Stack | 35 | ~850 | 30 min |
|
||||
|
||||
### Developer Productivity Gains
|
||||
|
||||
**Before Scaffolding**:
|
||||
- Setup time: 2-4 hours
|
||||
- Configuration errors: Common
|
||||
- Inconsistent structure: Yes
|
||||
- Missing best practices: Often
|
||||
|
||||
**After Scaffolding**:
|
||||
- Setup time: 5-30 minutes
|
||||
- Configuration errors: Rare
|
||||
- Consistent structure: Always
|
||||
- Best practices: Built-in
|
||||
|
||||
**Time Savings**: 80-90% reduction in project setup time
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
After scaffolding:
|
||||
|
||||
1. **Review generated code** - Understand structure and conventions
|
||||
2. **Customize for your needs** - Modify templates, add features
|
||||
3. **Run tests** - Verify everything works: `npm test` or `pytest`
|
||||
4. **Start development** - Add your business logic
|
||||
5. **Deploy** - Use provided deployment configuration

# My Worker API
|
||||
|
||||
Production-ready Cloudflare Workers API with TypeScript, Hono, and D1 database.
|
||||
|
||||
## Quick Start
|
||||
|
||||
\`\`\`bash
|
||||
# Install dependencies
|
||||
npm install
|
||||
|
||||
# Create D1 database
|
||||
wrangler d1 create my-worker-api-db
|
||||
|
||||
# Update wrangler.toml with database ID
|
||||
|
||||
# Run migrations
|
||||
npm run d1:migrate
|
||||
|
||||
# Start development server
|
||||
npm run dev
|
||||
|
||||
# Open http://localhost:8787/health
|
||||
\`\`\`
|
||||
|
||||
## API Endpoints
|
||||
|
||||
- `GET /health` - Health check
|
||||
- `GET /api/users` - List users (requires auth)
|
||||
- `GET /api/users/:id` - Get user by ID (requires auth)
|
||||
- `POST /api/users` - Create user (requires auth)
|
||||
- `PUT /api/users/:id` - Update user (requires auth)
|
||||
- `DELETE /api/users/:id` - Delete user (requires auth)
|
||||
|
||||
## Authentication
|
||||
|

||||
- **TanStack Router**: Type-safe routing
|
||||
- **TanStack Query**: Server state management
|
||||
- **TanStack Table**: Data tables
|
||||
- **Zod**: Runtime validation
|
||||
|
||||
**File**: `frontend/src/main.tsx`
|
||||
```typescript
|
||||
import { StrictMode } from 'react';
|
||||
import { createRoot } from 'react-dom/client';
|
||||
import { RouterProvider, createRouter } from '@tanstack/react-router';
|
||||
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
|
||||
import { routeTree } from './routeTree.gen';
|
||||
|
||||
const queryClient = new QueryClient();
|
||||
const router = createRouter({ routeTree });
|
||||
|
||||
createRoot(document.getElementById('root')!).render(
|
||||
<StrictMode>
|
||||
<QueryClientProvider client={queryClient}>
|
||||
<RouterProvider router={router} />
|
||||
</QueryClientProvider>
|
||||
</StrictMode>,
|
||||
);
|
||||
```

|
||||
|
||||
export const api = {
|
||||
users: {
|
||||
list: () => fetch(`${API_BASE}/api/users`).then(r => r.json()),
|
||||
get: (id: string) => fetch(`${API_BASE}/api/users/${id}`).then(r => r.json()),
|
||||
create: (data: any) =>
|
||||
fetch(`${API_BASE}/api/users`, {
|
||||
method: 'POST',
