Which is Better Node.js ORM Libraries?
sequelize vs bookshelf

Node.js ORM, or Object-Relational Mapping, is a programming technique that simplifies database interaction in Node.js applications. It enables developers to work with databases using JavaScript or TypeScript objects instead of raw SQL queries. This approach abstracts the complexities of database operations, allowing for a more object-oriented coding style. With features like cross-database compatibility, schema management, query building, and middleware support, Node.js ORM libraries, such as Mongoose, Prisma, Knex, Sequelize, TypeORM, Objection, Bookshelf, and Waterline, provide a convenient and consistent way to model, query, and manage data in various database systems, catering to different project needs and preferences in the Node.js ecosystem.
