Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

OOP vs. services for organizing business logic: is there a third way?
Sequent – CQRS and event sourcing

Event Store with Rails
Co-author of the Sequent gem (https://www.sequent.io) here. Can confirm that it’s a great gem to build event sourced applications with (as long as you’re using PostgreSQL). It’s very battle tested as it has been extracted from/used in a web based accounting system that currently holds about 1 billion events in the event store.

Using CQRS in a simple Phoenix API with Commanded
I have been curious about the concepts of event sourcing and CQRS for a while— obsessively reading books like Practical Microservices (Garofolo) and Architecture Patterns with Python (Percival, Gregory), along with documentation for libraries like Sequent (Ruby), Commanded (Elixir).

The Admin Framework for Minimalist
It can be used with Ruby on Rails or other frameworks because I implemented with trailblazer/cells.

Is ViewComponent the Future of Rails?
I agree, though cells does still have a larger following.

From partials to ViewComponents: writing reusable front-end code in Rails
So what about the world outside Rails defaults? There are quite a few independent projects trying to help build components in the Rails view layer, among the more famous being Draper (utilizing the decorators pattern) or Cells (full-featured components in views). In the end, we decided to take a deeper look into a relatively new one – the ViewComponent framework.

Cells - Introduction
GitHub has recently posted an article about view_component: https://github.blog/2020-12-15-encapsulating-ruby-on-rails-views/ Before it gets too popular I think I should share my experience with cells So that developers can have another chance to re-think and pick what to use for "encapsulated view components".

Why being a developer is frustrating — and why we do it anyway
This, combined with the fact that we are using cells gem for some view components, resulted in another couple of hours of hunting for the problem (it takes some time to debug what exactly and how exactly changed in Rails internals) and then fixing this problem. At this moment, I already spent over 8 hours debugging Rails internals, different gem internals, fixing application, fixing tests, screaming internally.
