In this article, our primary focus will be reviewing best Node.js ORMs (Object Rational Mapping)

Additionally, this article will clearly point out Node.js ORMs ideal solutions based on certain specific requirements.

What is an ORM

ORM solutions are very ideal because of their ability to facilitate data-driven API development. Due to several user’s needs, there is an urge for the data model of an application.

Usually, the ORMs operate as a super-level API to launch CRUD, with modern well-developed ORMs capable to initialize data through code. Additionally, ETL tools are easy to implement in ORM.

Furthermore, for effective developer experience, ORMs are important because;

  • They give a high-level API.
  • It can accommodate a single language.
