Sequelize vs Mongoose: Which One Should I Use?

What are the main differences between Sequelize and Mongoose?

Sequelize is an ORM for SQL databases, while Mongoose is an ODM for MongoDB. Sequelize uses SQL queries, whereas Mongoose uses MongoDB's query language.

Which one is better for a Node.js application?

It depends on your database choice. If you're using a SQL database, Sequelize is better. For MongoDB, Mongoose is the way to go.

Can you give me an example of how to define a model in both?

Sure! In Sequelize, you define a model like this: const User = sequelize.define('User', { name: Sequelize.STRING }); In Mongoose, it looks like this: const User = mongoose.model('User', new mongoose.Schema({ name: String }));

What are the advantages of using Sequelize over Mongoose?

Sequelize offers features like migrations, associations, and a more structured approach to SQL databases, which can be beneficial for complex applications.
