//npm install sequelize @types/sequelize

//Import the Sequelize class from the sequelize package in your TypeScript code.

import { Sequelize } from 'sequelize';

//Create an instance of the Sequelize class, and use it to connect to your database.

const sequelize = new Sequelize('database', 'username', 'password', {

  dialect: 'mysql',

});

//Define the model using the define method of the Sequelize instance. The define method takes the name of the model and an object containing the model's attributes and options as arguments.

const User = sequelize.define('User', {

  firstName: {

    type: Sequelize.STRING,

  },

  lastName: {

    type: Sequelize.STRING,

  },

});

//Use the sync method of the model to create the corresponding table in the database.

User.sync();

//Here is an example of a complete TypeScript model definition using Sequelize:

import { Sequelize } from 'sequelize';

const sequelize = new Sequelize('database', 'username', 'password', {

  dialect: 'mysql',

const User = sequelize.define('User', {
