Yes, in Node.js projects, ORM (Object-Relational Mapping) is often used for convenient database interaction, such as Sequelize or TypeORM.

ORM allows working with the database through objects and methods instead of writing raw SQL queries. This simplifies creating, reading, updating, and deleting data (CRUD), as well as managing relationships between tables.

Example of using Sequelize:

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

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

(async () => {
  await sequelize.sync();
  const user = await User.create({ username: 'ivan', birthday: new Date(1990, 1, 1) });
  console.log(user.toJSON());
})();

Thus, ORM helps abstract away from specific SQL syntax and speeds up development, especially when working with large and complex databases.
