🚀 How to migrate from CJS to ESM with Sequelize: ESM part

article.mjs

export default function article (sequelize, DataTypes) {
  const article = sequelize.define('article', {})

  article.associate = (models) => {
    article.belongsTo(models.user)
  }

  return article
}

index.mjs

import {Sequelize, DataTypes} from 'sequelize'
import article from './article.mjs'
import user from './user.mjs'

const sequelize = new Sequelize(process.env.DB_URL)
const models = {
  article: article(sequelize, DataTypes),
  user: user(sequelize, DataTypes),
}

Object.keys(models).forEach(key => {
  if (models[key].associate) {
    models[key].associate(models)
  }
})

models.sequelize = sequelize
export default models

main-esm.mjs

import models from './models-esm/index.mjs'

main()

async function main () {
  try {
    await models.sequelize.sync({force: true})
    await models.sequelize.close()
  } catch (err) {
    console.error(err)
  }
}

user.mjs

export default function user (sequelize, DataTypes) {
  const user = sequelize.define('user', {})
  return user
}
