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 use?

I think I'll go with Sequelize. What are the first steps?

First, install Sequelize and the database driver using npm. For example, for PostgreSQL, run npm install sequelize pg pg-hstore.

Got it! How do I connect to my database?

You can connect to your database by creating a new Sequelize instance with your database credentials. Here's a sample code snippet:

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

Thanks! How do I define a model?

You can define a model by extending the Sequelize Model class. Here's an example:

const { Model, DataTypes } = require('sequelize');
class User extends Model {}
User.init({
  username: DataTypes.STRING,
  password: DataTypes.STRING,
}, { sequelize, modelName: 'user' });
