Entities

Core domain models of the application — pure type definitions for business objects (User, Product, Message), their enums, and related constants. Stable, reusable, usable from any layer.

entities/
| --- user.ts                 # { id: string; name: string; email: string }
| --- product.ts              # { id: string; name: string; price: number }
| --- enums.ts                # { UserRole, ProductCategory }

Larger entities can use a folder (user/ with interfaces.ts, enums.ts, rules.ts, index.ts).

export type User = {
  id: number;
  name: string;
  email: string;
};

export enum UserRole {
  ADMIN = "admin",
  SIMLPE_JACK = "simple_jack",
}
