Creating a Designer

Basic Usage

import { createDomainDesigner } from '@ddd-tool/domain-designer-core'
const d = createDomainDesigner()

Optional Initialization Parameters

import { createDomainDesigner } from '@ddd-tool/domain-designer-core'
const d = createDomainDesigner({
  moduleName: 'order',
  ignoreValueObjects: ['time', 'name'],
})

Parameter	Type	Description	Default
moduleName	string	Module name, used as the basis for code packaging during code generation	ts filename
ignoreValueObjects	string[]	Ignored value object names. If names match during code generation, value objects won't be generated	[ 'time', 'id', 'pid', 'name', 'state', 'status', 'version', 'code', 'message', 'type', 'result', 'data', 'payload', 'meta', 'context', 'sorting' ]

Why is there an ignoreValueObjects property?

Answer: In normal design, we should use names with business meaning to define values.

For example: it should be userName, not just name.

But there are exceptions: in UserCreatedEvent, having a time attribute is normal because this time has weak business attributes - we just need a time value. Such vague attribute names shouldn't be treated as value objects during code generation.
