import MongooseJsonApi, { JsonApiInstanceMethods, JsonApiModel, JsonApiQueryHelper } from '@stantanasi/mongoose-jsonapi'
import mongoose, { HydratedDocument, Model, Schema, Types } from 'mongoose'

interface IArticle {
  _id: Types.ObjectId
  title: string
}

type ArticleInstanceMethods = JsonApiInstanceMethods

type ArticleQueryHelper = JsonApiQueryHelper
