Ruby on Rails applications often have boilerplate code around turning request parameters into filter criteria for the response. The controller allows the parameters, and the model includes scopes for simple attribute criteria, which the controller applies.

After writing lots of this code and seeing it written inconsistently, even within a single application, I built a gem to enable declarative filter parameters for Rails controllers.

A straightforward DSL allows developers to call out allowable filters, including validations, nested filters, and name overrides. There is no other code to write!

Stimulus is a popular open-source JavaScript library from the creators of Ruby on Rails. This fork enables controllers to be connected, making it easier to use composition with smaller, more focused controllers.

This open-source library is deliberately simple. It is a lightweight Ruby gem that enables developers to add pagination and sorting to Rails controllers. Out of the box, it provides bi-directional sorting on attributes, nested attributes, or scopes.

Inevitable applications need a small number of flags. Maybe it is to turn jobs on and off, and maybe it is to set thresholds for processing. If the settings do not need to change between deployments, then environment variables are a good choice.

However, if users want to change a value more frequently or want someone without the ability to do a deployment to change a value, another solution is needed. This Ruby gem provides it, allowing developers to quickly add run time settings wherever they make the most sense: on a job, on a model, or even on a PORO.
