6# Splitting Namespace Functions into Scopes
7 
8This rule defines how to organize functionality in a namespace by scope.
9 
10## Structure
11 
121. Split functionality into three scopes:
13   - `customer` - Functions related to customer operations
14   - `store` - Functions related to store operations  
15   - `admin` - Functions related to admin operations
16 
172. Create separate files for each scope:
18   - `customer.functions.ts` - Customer-related functions
19   - `store.functions.ts` - Store-related functions
20   - `admin.functions.ts` - Admin-related functions
21 
223. Create a main functions file (e.g., `functions.ts`) that:
23   - Imports all scope files
24   - Exports a context mapping function (`contextTo<namespace>FunctionMapping`)
25 
26## Implementation Rules
27 
281. **No cross-imports**: Do not import between scope files (customer/store/admin)
292. **Context mapping**: Create a mapping function that determines which function to use based on context parameters
303. **Exports**: Export all functions through the main functions file
31 
32## Example (Order namespace)
33 
34In `functions.ts`:
35```typescript
36import * as customer from './customer.functions';
37import * as admin from './admin.functions';
38import * as store from './store.functions';
39 
40export const contextToOrderFunctionMapping = ({
41  customerId,
42  storeKey,
43}: {
44  customerId?: string;
45  storeKey?: string;
46}): Record<string, Function> => {
47  if (customerId) {
48    return {
49      read_order: customer.readCustomerOrder,
50    };
51  }
52  if (storeKey) {
53    return {
54      read_order: store.readStoreOrder,
55      create_order_from_cart: store.createOrderFromCartInStore,
56      create_order_from_quote: store.createOrderFromQuoteInStore,
57      update_order: store.updateOrderByIdInStore,
58    };
59  }
60  return {
61    read_order: admin.readOrder,
62    create_order_from_cart: admin.createOrderFromCart,
63    create_order_from_quote: admin.createOrderFromQuote,
64    create_order_by_import: admin.createOrderByImport,
65    update_order: admin.updateOrder,
66  };
67};
