### Set up the database
First, set up your Supabase database:
1. Create a Supabase account at [supabase.com](https://supabase.com)
2. Create a new project in your Supabase dashboard
3. Once your project is ready, navigate to the **SQL Editor** from the sidebar
4. Run the following SQL commands to create the necessary tables for your ordering system:
For detailed Supabase setup instructions, see the [official Supabase documentation](https://supabase.com/docs/guides/getting-started).

### Menu Items Table
```sql
CREATE TABLE public.menu_items (
id SERIAL PRIMARY KEY,
category VARCHAR(50) NOT NULL,
name VARCHAR(100) NOT NULL,
description TEXT,
price NUMERIC(10, 2) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
CREATE INDEX idx_menu_items_category ON public.menu_items(category);
```
### Orders Table
```sql
CREATE TABLE public.orders (
id SERIAL PRIMARY KEY,
customer_phone VARCHAR(20) NOT NULL,
customer_address TEXT NOT NULL,
total_amount NUMERIC(10, 2) NOT NULL,
status VARCHAR(20) NOT NULL DEFAULT 'preparing',
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
CREATE INDEX idx_orders_status ON public.orders(status);
```
### Order Items Table
```sql
CREATE TABLE public.order_items (
id SERIAL PRIMARY KEY,
order_id INTEGER REFERENCES orders(id) ON DELETE CASCADE,
menu_item_id INTEGER REFERENCES menu_items(id) ON DELETE CASCADE,
quantity INTEGER NOT NULL DEFAULT 1,
price NUMERIC(10, 2) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
CREATE INDEX idx_order_items_order_id ON public.order_items(order_id);
CREATE INDEX idx_order_items_menu_item_id ON public.order_items(menu_item_id);
```
### Sample Menu Data
```sql
INSERT INTO menu_items (category, name, description, price) VALUES
('Pizza', 'Margherita', 'Fresh tomatoes, mozzarella, basil', 12.99),
('Pizza', 'Pepperoni', 'Pepperoni, mozzarella, tomato sauce', 14.99),
('Burger', 'Classic Burger', 'Beef patty, lettuce, tomato, onion', 10.99),
('Burger', 'Cheeseburger', 'Beef patty, cheese, lettuce, tomato', 11.99),
('Drinks', 'Coke', 'Coca-Cola 330ml', 2.99),
('Drinks', 'Water', 'Mineral water 500ml', 1.99);
```
#### Supabase Client Configuration
The example already includes a `lib/supabase.ts` file that initializes the Supabase client:
```typescript
import { createClient } from "@supabase/supabase-js";
// Supabase configuration - add these to your .env file
const supabaseUrl = process.env.SUPABASE_URL || "";
const supabaseAnonKey = process.env.SUPABASE_ANON_KEY || "";
export const supabase = createClient(supabaseUrl, supabaseAnonKey);
```
This file provides a Supabase client instance that all the tools use to interact with the database. Make sure your environment variables are properly set in the `.env` file.
#### Start the development server
```bash
npm run dev
```
Once your server starts successfully, you see:
```bash
