How to use the actionhero.api.sequelize function in actionhero

async initialize () {
    api.models = {}

    const sequelizeInstance = new Sequelize(
      api.config.sequelize.database,
      api.config.sequelize.username,
      api.config.sequelize.password,
      api.config.sequelize
    )

    api.sequelize = {
      sequelize: sequelizeInstance,

      connect: async () => {
        const dir = path.normalize(api.projectRoot + '/models')
        fs.readdirSync(dir).forEach((file) => {
          var nameParts = file.split('/')
          var name = nameParts[(nameParts.length - 1)].split('.')[0]
          api.models[name] = api.sequelize.sequelize.import(dir + '/' + file)
        })

        await api.sequelize.sequelize.sync()
      },

      disconnect: async () => {
        await api.sequelize.sequelize.close()
      }

fs.readdirSync(dir).forEach((file) => {
          var nameParts = file.split('/')
          var name = nameParts[(nameParts.length - 1)].split('.')[0]
          api.models[name] = api.sequelize.sequelize.import(dir + '/' + file)
        })

async stop () {
    await api.sequelize.disconnect()
  }
}
