description: Create a new value object following DDD patterns. Use when modeling domain concepts without identity (email, money, address, etc).
argument-hint: [module-name] [value-object-name]
disable-model-invocation: true

Create a new value object "$1" in the $0 module.

Create file: src/modules/$0/domain/$1.ts

Requirements:

  • •Extend ValueObject<Props> from '@shared/ddd/ValueObject'
  • •Immutable - no setters, only getters
  • •Equality based on values, not identity
  • •Private constructor with static create() factory method
  • •Validation in create() method using Guard pattern
  • •Return Result<ValueObjectName> from create()
  • •NO framework dependencies

Value Object characteristics:

  • •Measures, quantifies, or describes a domain concept
  • •Immutable
  • •Compared by value equality
  • •Side-effect free behavior
  • •Self-validated

Example value objects:

  • •Email (validates email format)
  • •Money (amount + currency)
  • •Address (street, city, country)
  • •DateRange (start + end dates)

Follow the ValueObject pattern from existing examples in the codebase.
