The Decree Design Pattern (Ruby on Rails)
check out the `light-service` gem - it lets you create services that use this pattern and compose them into complex flows: https://github.com/adomokos/light-service

How to avoid if/else with different ramifications
Similar to the above recommendations of Railway Orientated Programming and the Interactor gem, I use the Light Service gem. While it can sometimes be a bit verbose it excels in code reuse, testability, and composition.

The Ruby Unbundled Series: Services vs. Objects - The Battle for Decomposition and Reuse
You can implement the service pattern as a PORO, but it helps to use one of the gems available to aid in code structure, orchestration, and error handling. The LightService gem provides a nice implementation without adding hardly any overhead. It’s design is very simple, as shown in the diagram below. An organizer is used to define the sequential workflow, which is made up of one or more actions. An error in any of the actions will short-circuit the entire workflow.

Build Load More Pagination with Pagy and Rails Hotwire
Now, let's dive into the pagination part of this post: setting up Pagy for handling pagination in our Rails application. If you haven't included the Pagy gem in your project, you'll need to add it manually. Here's how you can do it:
-
Pagination in Rails with Pagy gem
Several gems are available for pagination in Rails, but the Pagy gem is one of the most popular and efficient. It is a fast and lightweight library that provides a simple and flexible API. In this article, we’ll explore how to use it to implement pagination in Rails.

Rux: A JSX-inspired way to render view components in Ruby
> Am I understanding correctly that there’s a significant difference in performance between using a ViewComponent + a partial vs. a ViewComponent which renders html via a tag - from inside the component?
I don't think there will be much difference at all in everyday use, but some libraries that value performance don't avoid templates for that reason, Pagy for example.

Personally I omit them in my projects whenever we want to customise attributes, I hate seeing stuff like this in templates:

A powerful search feature with what Rails provides out of the box
The next step was about backporting the templates, adding Pagy gem for handling pagination and creating the controller. I was then able to show the listings with the models, but the filtering was not working.

The Ultimate Search for Rails - Episode 1
On the backend, we'll need a few tools. Apart from the classics (ActiveRecord scopes and the pg_search gem), you’ll see how the (yet officially unreleased but production-tested) all_futures gem, built by SR authors, will act as an ideal ephemeral object to temporarily store our filter params and host our search logic. Finally, we’ll use pagy for pagination duties.

Load More Pagination in Rails with Hotwire Turbo Streams
For pagination I tend not to use gems like pagy or kaminari, instead implement this functionality just using limit and offset.

Kaminari hooks onto ActiveRecord associations and makes it super easy to page them. Pagy is another option that seems to have a solid API but I haven't tried it yet.

Re-Wheel series part 1 - How does Rails' find_each work?
But how is this implemented? Well, if you use pagination in your index methods with gems like pagy, kaminari or will_paginate you will find that the same idea is happening here, they are using the power of SQL's LIMIT and OFFSET to fetch only a portion of the data each time. So in the 1 million users example, find_each will perform 1000 thousand queries with a limit of 1000 while changing the offset properly so we don't miss any record.
