Objection.js is a Node.js ORM (Object-Relational Mapping) library designed for relational databases. It provides a straightforward and flexible way to interact with database tables using JavaScript objects, allowing developers to define models, perform queries, and manage data relationships without writing raw SQL. Objection.js is built on top of the SQL query builder Knex.js and supports features such as eager loading, validation, and transaction management.

About Objection.js
Objection.js was created in 2015 by Sami Koskimäki. It was developed to address the need for a powerful yet simple ORM for Node.js applications, providing a more flexible alternative to existing solutions. The library aimed to combine the benefits of raw SQL queries with the convenience of an ORM, allowing developers to work with JavaScript objects while retaining control over database interactions.
Strengths of Objection.js include its flexibility, strong integration with Knex.js, and support for complex data relationships and validations. It allows developers to write expressive queries while maintaining control over database interactions. Weaknesses may include a steeper learning curve for those unfamiliar with SQL or the Knex.js query builder and potentially less community support compared to more popular ORMs. Competitors of Objection.js include Sequelize, TypeORM, and Bookshelf.js, each offering different features and levels of abstraction for interacting with databases in Node.js applications.

How to hire a Objection.js expert
An Objection.js expert must have strong proficiency in JavaScript and Node.js, as these are foundational for working with the library. They should possess a solid understanding of SQL and relational database concepts, given Objection.js's reliance on Knex.js for query building. Familiarity with Knex.js itself is crucial, as it underpins many of Objection.js's features. Additionally, expertise in designing and managing complex data models and relationships is important, along with skills in handling database transactions and performing data validation within the ORM context.
