How fahim-khandakar/seller-mama-backend works

Seller Mama is a commerce backend exposing versioned Express APIs for authentication, catalog management, coupons, orders, and users. Requests enter through the application and route registry, then domain controllers invoke services that perform domain work; services use Mongoose models and shared query, token, and media utilities. The order service references product, coupon, and user data. The README is empty, and route wiring, database connection details, and several listed modules were not excerpted, so those links are omitted rather than inferred.

Main entry points: product.service.ts Product Service · order.service.ts Order Service · QueryBuilder.ts Query Builder · app.ts Express App
