PHP ActiveRecord VS Objection.js

• Familiar ActiveRecord pattern
  Follows the Active Record design pattern popularized by Ruby on Rails, so each model maps to a database table and each instance maps to a row. Developers who know Rails can pick it up quickly, and common CRUD operations need very little code.
• Minimal configuration
  Models work with little setup. Table names are inferred from class names and column attributes are discovered automatically from the database schema, so there is no need for XML or YAML mapping files or for declaring properties by hand.
• Built-in associations
  Supports has_many, belongs_to, has_one and has_many through relationships, declared with simple static properties on the model. Eager loading with the 'include' option helps reduce N+1 query problems.
• Validations and callbacks
  Offers built-in validators such as presence, length, format, uniqueness, numericality and inclusion, along with lifecycle callbacks like before_save and after_create. This keeps business logic in the model and reduces boilerplate.
• Dynamic finders and multi-database support
  Provides dynamic finders like find_by_name_and_email, plus find options for conditions, order, limit and joins. It runs on several databases through PDO, including MySQL, PostgreSQL, SQLite and Oracle, and supports multiple connections.

Possible disadvantages

• Stagnant maintenance
  Development has been slow, with infrequent releases and a long backlog of open issues and pull requests. Support for newer PHP versions (7.x, 8.x) often depends on community forks, which creates risk for long-term projects.
• Limited modern features
  Lacks modern conveniences found in Eloquent or Doctrine, such as a built-in migration system, a rich query builder, advanced relationship types like polymorphic relations, and first-class support for modern PHP typing.
• Active Record pattern limitations
  Coupling models directly to database tables can make complex domain logic harder to organize and test. It is less suited to large applications with complex schemas than a Data Mapper ORM such as Doctrine.
• Sparse documentation and community
  The official documentation is basic and sometimes outdated, and the community is much smaller than those of Laravel Eloquent or Doctrine. Finding tutorials, answers and up-to-date examples can be hard.
• Performance and magic overhead
  Heavy use of magic methods and runtime schema inspection adds overhead and makes code harder to debug, and IDE autocompletion is weaker without extra annotations. Complex queries often require falling back to raw SQL.

• Simplicity
  Objection.js provides a simple and intuitive syntax for defining models and relations, making it easy for developers to set up and manage database interactions.
• Flexibility
  It allows for raw SQL queries alongside its ORM capabilities, giving developers the flexibility to optimize and customize queries as needed.
• Powerful Querying
  Objection.js offers powerful querying capabilities with support for eager loading, filtering, and sorting, which are highly customizable and efficient.
• Compatibility with Knex.js
  Objection.js is built on top of Knex.js, allowing developers to leverage the robust query building of Knex.js while benefiting from Objection's ORM features.
• JavaScript and TypeScript Support
  With first-class support for both JavaScript and TypeScript, Objection.js is versatile and can fit into projects using either language.
• Good Documentation
  The library is accompanied by comprehensive documentation, providing detailed guidance and examples for implementation and use.

Possible disadvantages

• Learning Curve
  Despite its simplicity, understanding its full potential, especially for developers new to ORMs, can take time due to its advanced and flexible feature set.
• Dependency on Knex.js
  While leveraging Knex.js is a strength, it also means that any limitations or bugs in Knex.js can directly affect the reliability and functionality of Objection.js.
• Size and Complexity of Projects
  For very simple projects, Objection.js might be considered overkill, providing more functionality than necessary, which can complicate maintenance.
• No Built-in Migration Tool
  Unlike some ORMs, Objection.js does not include a built-in migration tool, requiring developers to use Knex.js migrations or other tools.
• Community and Ecosystem
  While active, the community and ecosystem around Objection.js are not as large as some other popular ORMs, potentially limiting third-party extensions and plugins.

• Top 6 ORMs for Modern Node.js App Development

  Objection.js is a SQL-friendly ORM for Node.js that supports various relational databases, including PostgreSQL, MySQL, and SQLite. It provides a flexible and expressive query builder. Objection.js is known for its expressive syntax,... - Source: dev.to / about 3 years ago

• Best ORM library?

  I don't think there's a best per say, but we did recently use Objection on our project. Did the job well, only issue is there's no constructor for the DB Models but it's just something you work around... Source: over 3 years ago

• Simple postgres 'ORM' for node project?

  If you aren't using TypeScript I'd very much recommend Objection.js, I've used it multiple times and no complaints so far. You can pass raw SQL queries to it as well so I'm sure it would be a good fit for your project! Source: over 3 years ago
