How do I set up an ORM in Node.js?

To set up an ORM in Node.js, you can use libraries like Sequelize or TypeORM. Which one would you like to know about?

Let's go with Sequelize. What are the steps?

First, install Sequelize and the database driver using npm. Then, initialize Sequelize in your project.

What database drivers do I need for PostgreSQL?

For PostgreSQL, you need to install the 'pg' package along with Sequelize. You can do this with: npm install sequelize pg pg-hstore.

Can you show me a basic example of defining a model?

Sure! Here's a simple example:

const { Sequelize, DataTypes } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'postgres',
});

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