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.

Anaconda
A free and open-source distribution of the Python and R programming languages for scientific computing, that aims to simplify package management and deployment. Package versions are managed by the package management system conda.
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
Mongoid
The philosophy of Mongoid is to provide a familiar API to Ruby developers who have been using Active Record or Data Mapper, while leveraging the power of MongoDB's schemaless and performant document-based design, dynamic queries, and atomic modifier operations.
