Fight!

Popularity

Sequelize is a more established and widely used ORM (Object-Relational Mapping) library in the Node.js ecosystem. It has been around for a longer time and has a larger community and user base. On the other hand, @mikro-orm/core is a relatively newer library but has gained popularity due to its simplicity and developer-friendly approach.

Ease of Use

Both @mikro-orm/core and Sequelize provide easy-to-use APIs for interacting with databases. However, @mikro-orm/core takes a more opinionated approach and provides a simpler and more intuitive API, making it easier for developers to get started. Sequelize, on the other hand, offers more flexibility and customization options, but it can be more complex to set up and configure.

Database Support

Sequelize supports a wide range of databases including MySQL, PostgreSQL, SQLite, and MSSQL. It provides a consistent API for working with different database systems. @mikro-orm/core, on the other hand, primarily focuses on supporting PostgreSQL, MySQL, and SQLite, but it also has experimental support for MongoDB.

Performance

In terms of performance, Sequelize is known to be a bit slower compared to @mikro-orm/core. @mikro-orm/core utilizes a lightweight and efficient query builder, resulting in faster query execution. However, the performance difference might not be significant for most applications unless dealing with extremely high loads or complex queries.

Community and Documentation

Sequelize has a larger and more mature community, which means there are more resources, tutorials, and community support available. It also has extensive documentation covering various aspects of the library. @mikro-orm/core, being a newer library, has a smaller community and fewer resources available, but it has a growing community and its documentation is improving over time.

TypeScript Support

Both @mikro-orm/core and Sequelize have good TypeScript support. They provide type definitions and allow developers to write type-safe code when working with databases. However, @mikro-orm/core has a more seamless integration with TypeScript and provides better type inference, making it a preferred choice for TypeScript projects.
