How can I use ORMs in Node.js?

You can use ORMs like Sequelize or TypeORM to interact with databases in Node.js. Would you like a code example?

Yes, please provide a simple example using Sequelize.

Sure! First, install Sequelize and a database driver. Then, you can define a model like this:

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

const User = sequelize.define('User', {
  username: {
    type: DataTypes.STRING,
    allowNull: false
  },
  birthday: {
    type: DataTypes.DATE
  }
});

How do I sync the model with the database?

You can sync the model using sequelize.sync(). This will create the table if it doesn't exist:

sequelize.sync();
