Objection.js
Objection.js is an object-relational mapper for Node.js that maps SQL database tables to classes and rows to model instances. It functions as a high-level abstraction layer built on top of the Knex.js query builder to provide structured model definitions and relational data mapping.
The project distinguishes itself through its ability to manage complex object graphs, allowing for the persistence and eager-loading of deeply nested related data in single operations. It incorporates a data integrity layer that uses JSON schema validation to verify model instances before they are persisted to the database.
The toolset covers broad relational modeling capabilities, including the definition of associations between entities, atomic transaction management, and support for composite primary keys. It also provides utilities for document storage by persisting complex objects as JSON strings within relational columns and uses mixins to share reusable logic across different data models.
