Sequelize Deprecated Error Message

Question

I\'m very new to Node and I\'m getting my head around how ORM and Sequelize works. I\'ve been on the Sequelize website and copied the connection string and altered it to work wi

Answer 1

Updating to version:

"sequelize": "^5.8.6"

and removing operatorsAliases param from

new Sequelize()

removed depreciation warning

Answer 2

const sequelize = new Sequelize({
  username: process.env.DBUSERNAME,
  host: process.env.DBHOST,
  database: process.env.DBNAME,
  password: process.env.DBPASSWORD,
  dialect: 'postgres',
  define: {
    timestamps: false,
  },
  operatorsAliases: false,
  pool: {
    max: 5,
    min: 0,
    idle: 10000
  },

});

Answer 3

These were the best explanations that I found for this deprecation warning:

https://github.com/sequelize/sequelize/issues/8417

http://docs.sequelizejs.com/manual/tutorial/querying.html#operators-aliases

Adding "operatorsAliases: false" did override the warning message in my application.

const Sequelize = require('sequelize')
const sequelize = new Sequelize(
  DB_NAME,
  USERNAME, 
  PASSWORD,
  {
    host: HOSTNAME,
    dialect: 'mysql',
    logging: false,
    freezeTableName: true,
    operatorsAliases: false
  }
)

Note: as of sequelize@4.20.1 I started receiving "Invalid value" errors from Sequelize. I relented and used the following code to enable symbol operators:

const Sequelize = require('sequelize')
const Op = Sequelize.Op
const sequelize = new Sequelize(
  DB_NAME,
  USERNAME, 
  PASSWORD,
  {
    host: HOSTNAME,
    dialect: 'mysql',
    logging: false,
    freezeTableName: true,
    operatorsAliases: {
      $and: Op.and,
      $or: Op.or,
      $eq: Op.eq,
      $gt: Op.gt,
      $lt: Op.lt,
      $lte: Op.lte,
      $like: Op.like
    }
  }
)
