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

// Create a Sequelize instance
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql',
});

// Define a model
const User = sequelize.define('User', {
  username: {
    type: DataTypes.STRING,
    allowNull: true, // Allows null values
    defaultValue: 'Guest', // Default value if null
  },
});

// Sync the model with the database
sequelize.sync()
  .then(() => {
    console.log('Model synced with database');
  })
  .catch((error) => {
    console.error('Error syncing model:', error);
  });
