Model sequelize nodejs TypeError: (intermediate value).init is not a function

Question

I'm making an application with ORM sequelize for the first time, I got to the model part, but when I run it it points me to an error that I can't solve, if anyone knows or can help me, thank you in advance, I'll leave the model code below and the error message

const Model = require('sequelize');
const DataTypes = require('sequelize');

class User extends Model {
  static init(sequelize) {
    super.init({
      name: DataTypes.STRING,
      password: DataTypes.INTEGER,
      email: DataTypes.STRING,
    }, {
      sequelize
    })
  }
}

module.exports = User;

this is the error message: super.init({ ^

I think your imports are not correct. It should be

const { Sequelize, DataTypes, Model } = require('sequelize');

Also, why not define models with sequelize.define. If you are defining them through extending Model, then try this

const { Sequelize, DataTypes, Model } = require('sequelize');
const sequelize = new Sequelize('sqlite::memory:');

class User extends Model {}

User.init({
  name: DataTypes.STRING,
  password: DataTypes.INTEGER,
  email: DataTypes.STRING,
},{
  sequelize
});

console.log(User === sequelize.models.User); // true
