Domain-Driven Development with easy-model

In e-commerce application development, modules like product management, shopping carts, and order processing often involve complex business logic. easy-model's model-driven architecture can effectively organize this domain knowledge, improving code maintainability. This article demonstrates how to implement domain-driven development in e-commerce using easy-model through real-world examples. Product Management Model Products are the core domain in e-commerce. We can create a ProductModel to encapsulate product state and business logic: import { useModel } from " easy-model " ; class ProductModel { product = { id : "" , name : "" , price : 0 , stock : 0 , category : "" }; constructor ( initialProduct : typeof this . product ) { this . product = initialProduct ; } updateStock ( newStock : number ) { if ( newStock < 0 ) throw new Error ( " Stock cannot be negative " ); this . product . stock = newStock ; } isAvailable () { return this . product . stock > 0 ; } applyDiscount ( discountPerc
