Modules are classes decorated with @Module() that organize application structure. They group related controllers, services, and other providers together.
@Module({
imports: [DatabaseModule], // Other modules to import
controllers: [UserController], // Controllers in this module
providers: [UserService], // Services/providers in this module
exports: [UserService] // Providers to export for other modules
})
export class UserModule {}
