What is Sequelize and how do I use it?
Sequelize is a promise-based Node.js ORM for SQL databases. It allows you to interact with your database using JavaScript.
Can you show me how to set it up in a Node.js project?
Sure! First, install Sequelize and the database driver using npm. For example, for PostgreSQL: npm install sequelize pg pg-hstore.
How do I define a model in Sequelize?
You can define a model by extending Model from Sequelize. For example: class User extends Model {} and then define attributes.
What are migrations and how do I use them?
Migrations are version control for your database. You can create them using sequelize-cli to manage changes to your database schema.
