Objection.js
Objection.js is an ORM (Object-Relational Mapping) library for Node.js, built on top of the Knex SQL query builder. It provides a declarative, model-based approach to database interactions, allowing developers to work with JavaScript objects instead of raw SQL queries. It supports features like eager loading, transactions, and validation, making it suitable for relational databases like PostgreSQL, MySQL, and SQLite.
Developers should learn Objection.js when building Node.js applications that require efficient and maintainable database operations with relational databases, as it simplifies complex queries and reduces boilerplate code. It is particularly useful for projects using Knex for query building, as it integrates seamlessly, offering a higher-level abstraction for data modeling and relationships. Use cases include web APIs, enterprise applications, and systems where data integrity and relational mappings are critical.
