## Database Patterns

### Prisma Schema

```prisma
generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

model User {
  id        String   @id @default(cuid())
  email     String   @unique
  name      String?
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}

model Post {
  id        String   @id @default(cuid())
  title     String
  content   String?
  published Boolean  @default(false)
  authorId  String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}
```

### Database Client Singleton

```typescript
// src/lib/db.ts
import { PrismaClient } from '@prisma/client'

const globalForPrisma = globalThis as unknown as {
  prisma: PrismaClient | undefined
}

export const db =
  globalForPrisma.prisma ??
  new PrismaClient({
    log: ['query'],
  })

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = db
```

### Database Commands

```bash
bun run db:push      # Push schema changes
bun run db:generate  # Generate Prisma client
bun run db:migrate   # Create migration
bun run db:reset     # Reset database
```

---

## WebSocket Integration

### Server (Socket.io)

```typescript
// examples/websocket/server.ts
import { createServer } from 'http'
import { Server } from 'socket.io'

const httpServer = createServer()
const io = new Server(httpServer, {
  path: '/',
  cors: { origin: "*", methods: ["GET", "POST"] },
  pingTimeout: 60000,
  pingInterval: 25000,
})

interface User { id: string; username: string }
interface Message {
  id: string
  username: string
  content: string
  timestamp: Date
  type: 'user' | 'system'
}

const users = new Map<string, User>()

io.on('connection', (socket) => {
  socket.on('join', (data: { username: string }) => {
    const user: User = { id: socket.id, username: data.username }
    users.set(socket.id, user)
    io.emit('user-joined', { user, message: createSystemMessage(`${data.username} joined`) })
    socket.emit('users-list', { users: Array.from(users.values()) })
  })

  socket.on('message', (data: { content: string; username: string }) => {
    const message = createUserMessage(data.username, data.content)
    io.emit('message', message)
  })

  socket.on('disconnect', () => {
    const user = users.get(socket.id)
    if (user) {
      users.delete(socket.id)
      io.emit('user-left', { user, message: createSystemMessage(`${user.username} left`) })
    }
  })
})

httpServer.listen(3003)
```

### Client (React)

```typescript
// examples/websocket/frontend.tsx
'use client';

import { useEffect, useState } from 'react';
import { io } from 'socket.io-client';

export default function SocketDemo() {
  const [socket, setSocket] = useState<any>(null);
  const [isConnected, setIsConnected] = useState(false);

  useEffect(() => {
    // Use XTransformPort instead of direct port
    const socketInstance = io('/?XTransformPort=3003', {
      transports: ['websocket', 'polling'],
      reconnection: true,
      reconnectionAttempts: 5,
      reconnectionDelay: 1000,
    });

    setSocket(socketInstance);

    socketInstance.on('connect', () => setIsConnected(true));
    socketInstance.on('disconnect', () => setIsConnected(false));
    socketInstance.on('message', (msg) => { /* handle message */ });

    return () => socketInstance.disconnect();
  }, []);

  return ( /* JSX */ );
}
```

```

---

## File Output Pattern

Generated files are saved to:
```
/home/z/my-project/download/
```

Or in this reference codebase:
```
~/reference-codebases/z-ai-tooling/download/
```

---

## Key Patterns

### 1. Prisma Singleton
Prevents multiple PrismaClient instances in development.

### 2. WebSocket Port Transformation
Use `XTransformPort` query param instead of direct port numbers.

### 3. Component Structure
All UI components use:
- `cva` (class-variance-authority) for variants
- `cn` utility for class merging
- Radix primitives for accessibility

### 4. API Routes
```typescript
// src/app/api/route.ts
import { NextResponse } from "next/server";

export async function GET() {
  return NextResponse.json({ message: "Hello, world!" });
}
```

### 5. Backend-Only SDK Usage
`z-ai-web-dev-sdk` MUST only be used in:
- API routes (`src/app/api/`)
- Server components
- Server actions
