For example when i create CRUD of blog

Usecase : Delete Article

When i delete article, need to remove comment.
But when create comment, need to validation article

// article-comment.service.ts
async createComment(articleId: string, comment: string) {
  const article = articleService.get(articleId)
  if (!article) throw new SomeException()

  // ... create comment
}

async remove(articleId) {
 
}

// article.service.ts
async deleteArticle(articleid: string) {
  // ... validation

  commentService.remove(articleId)
}

async get(articleId: string)  {
  return repository.find(articleId)
}

articleService and commentService have circular dependency, How can i avoid it?

I don’t want to use ForwardRef..

Someone says, use EventEmitter and Use SharedModule? But What’s the best way i didn’t know..

Please give me advice, Thank you
