# Stacks Commerce

Comprehensive e-commerce module with 13 sub-modules and 20+ models.

## Key Paths
- Core package: `storage/framework/core/commerce/src/`
- Default functions: `storage/framework/defaults/functions/commerce/`
- Default models: `storage/framework/defaults/models/commerce/`

## Commerce Namespace

```typescript
import { commerce } from '@stacksjs/commerce'

// 13 sub-modules
commerce.products      // Product CRUD
commerce.coupons       // Coupon management
commerce.customers     // Customer management
commerce.errors        // Error tracking
commerce.giftCards     // Gift card management
commerce.orders        // Order management
commerce.payments      // Payment processing
commerce.restaurant    // Restaurant features
commerce.shippings     // Shipping management
commerce.tax           // Tax rate management
commerce.waitlists     // Waitlist management
commerce.devices       // Print device management
commerce.receipts      // Receipt management
```

## Sub-Module Operations

## Integration with Payments
Commerce works with `@stacksjs/payments` for Stripe integration:
```typescript
import { Payment } from '@stacksjs/payments'
await Payment.charge(customer, order.totalAmount, paymentMethodId)
```

## Dashboard Routes
All commerce models have dashboard views at `/dashboard/commerce/*`.

## Gotchas
- Commerce models are auto-generated — edit definitions, not generated files
- Use `buddy make:migration` when changing commerce schemas
- Order `observe: true` emits events on create/update/delete
- Products have JSON fields for allergens and nutritionalInfo
- Cart expiry is tracked via `expiresAt` field
- Coupon types: `fixed_amount` or `percentage`
- Gift card codes are unique and auto-generated
- License keys follow XXXX-XXXX-XXXX-XXXX-XXXX format
- Product dashboard is highlighted (`dashboard: { highlight: true }`)
- Default seeder counts: Product(10), Order(20), Review(50), Payment(50)
