It allows developers to define models, manage relationships, and perform CRUD operations in a more intuitive and organized manner. While Sequelize is a popular choice for ORM in Node.js applications, there are several alternatives worth considering:
bookshelf is an ORM for Node.js that is built on top of the Knex.js SQL query builder. It provides a simple and flexible way to work with relational databases, allowing developers to define models and relationships easily. Bookshelf supports features like eager loading, virtuals, and pagination, making it a good choice for applications that require a lightweight ORM with a focus on simplicity and flexibility. If you are already using Knex.js for database queries, Bookshelf can be a natural fit.
knex is a SQL query builder for Node.js that provides a powerful and flexible way to build and execute SQL queries. While not an ORM in the traditional sense, Knex allows developers to write SQL queries in a programmatic way, making it easier to work with databases. It supports multiple database engines and provides features like migrations and seed management. If you prefer to have more control over your SQL queries and do not need the full abstraction of an ORM, Knex is a great choice.
mongoose is an ODM (Object Data Modeling) library for MongoDB and Node.js.
