node js problem in connecting to sql server

Question

Dialect needs to be explicitly supplied as of v4.0.0 I am trying to connect an existing SQL server file to my node js app

the code in index.js

const Sequelize = require("sequelize");
const sequelize = new Sequelize(dbConfig.DB, dbConfig.USER,  {
  host: dbConfig.HOST,
  port: dbConfig.PORT,
  dialect: dbConfig.dialect,
  pool: {
    max: 5,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
});
const db = {};
db.Sequelize = Sequelize;
db.sequelize = sequelize;
db.tutorials = require("./tutorial.model.js")(sequelize, Sequelize);
module.exports = db;```


the db conf
```module.exports = {
    HOST: "localhost",
    PORT: "1434",
    USER: "****",
    DB: "***",
    dialect: 'mssql',
    pool: {
      max: 5,
      min: 0,
      acquire: 30000,
      idle: 10000
    }
  };```
