Mongoose vs Sequelize: What are the differences?

What is Mongoose? MongoDB object modeling designed to work in an asynchronous environment. Let's face it, writing MongoDB validation, casting and business logic boilerplate is a drag. That's why we wrote Mongoose. Mongoose provides a straight-forward, schema-based solution to modeling your application data and includes built-in type casting, validation, query building, business logic hooks and more, out of the box.

What is Sequelize? Easy-to-use multi sql dialect ORM for Node.js & io.js. Sequelize is a promise-based ORM for Node.js and io.js. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite and MSSQL and features solid transaction support, relations, read replication and more.

Mongoose belongs to "Object Document Mapper (ODM)" category of the tech stack, while Sequelize can be primarily classified under "Object Relational Mapper (ORM)".

"Well documented" is the top reason why over 14 developers like Mongoose, while over 17 developers mention "Good ORM for node.js" as the leading cause for choosing Sequelize.

Mongoose and Sequelize are both open source tools. Sequelize with 18.9K GitHub stars and 2.99K forks on GitHub appears to be more popular than Mongoose with 18.8K GitHub stars and 2.62K GitHub forks.

According to the StackShare community, Mongoose has a broader approval, being mentioned in 85 company stacks & 88 developers stacks; compared to Sequelize, which is listed in 38 company stacks and 33 developer stacks.

    Reviews of Mongoose and Sequelize
    Review ofMongooseMongoose

    I inherited a stack where Mongoose is used in the database layer.

    It's been several months and it's still the single highest source of daily WT*s in my backend development. The API is full of irregularities and the design is a poor mix of object-orientation and stateful objects with a lot implicit behavior. Mongoose made the choices of taking the worst parts of ORMs and using them in a context where the benefits of ORMs don't apply. The only reason I'm keeping it is its handy .populate() feature. Expect bad surprises!

    Used it for full stack web application development, especially to interact with MySQL/ MariaDB / PostgreSQL server.

    We use mongoose and node-native for database querying.
