Objection.js features and specs

  • 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.

Possible disadvantages of Objection.js

  • 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.

  • 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 (https://vincit.github.io/objection.js/). 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
  • Is it best practice to use classes with extends?
    You should look into Objection.js. IMHO using that will make your life much easier as it seems you are trying to reimplement it's features in this sample code. Source: almost 4 years ago
  • Exploring the repository pattern with TypeScript and Node
    Next, let’s set up the database for our newly created Nest application. I’ll be using PostgreSQL, but you can use any of the databases Knex supports. To interact with our database, we’ll be using Objection.js, which is an ORM for Node.js built on top Knex. For this tutorial, we’ll be using Nest Objection, a Nest module for Objection. - Source: dev.to / almost 4 years ago

  • Recommendations for Learning SQL
    I learned off of Mode Analytics SQL tutorial. It's free and I use it as a reference when I forget syntax. From there, my learning style is to grind on practical questions that I would get as a data analyst. So I would recommend stratascratch because all their questions are from real data science interviews which not only test for syntax but edge cases and business logic. Other platforms basically only test for... Source: over 3 years ago
  • How do i practice SQL to be real world ready?
    There was a comment here about using Leetcode, Hackerrank, SQL fiddle, etc to keep learning SQL. However, if you're aim is to go into data analytics you need to go beyond learning syntax and understand edge cases and business context. You should grind on some data analytics/data science focused platforms like stratascratch and interviewquery. They have hundreds of questions with many free ones for your to practice.

  • Brushing up on SQL for a job interview
    If you want some practice interview questions, check out DataLemur and/or StrataScratch. They helped me immensely in preparing for technical interviews. Source: over 3 years ago
