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.

RubyJS-Vite
It's been a long time dream for me since about 2013 when I started getting deep into Ruby and Rails, to be able to write Ruby code for the frontend instead of JavaScript. I was a lover and adopter of CoffeeScript (which had it's flaws and imperfections), but that mostly got killed by ES6. I wrote some PoCs with Opal[1] that felt pretty good to write, but the overhead was rough (this was many years ago so things might be different now) and I never really felt like I didn't have to know about or care about the underlying javascript. I tend to discard leaky abstractions as I feel they often add more complexity than they were meant to cover in the first place.
Has anybody used this or Opal or anything else? What is the state of "write your frontend in Ruby" nowadays?

Non-code contributions are the secret to open source success

Coming to grips with JS: a Rubyist's deep dive
But we shouldn't overstate the difference: the JS and Ruby object models are actually similar in how dynamic both of them are. This makes Ruby-to-JS compilers like Opal easier to implement, according to an Opal maintainer.

GCC Adopts a Code of Conduct
Not the OP, but from what I remember they would seek out every possible opportunity in every single possible open source community they could find and propose the CoC that they wrote. 0 contributions to the projects, with the exception of demanding that people implement incredibly verbose CoC's in their projects under the guise of "protecting the minorities contributing to the projects".
Most infamous instance is probably this one, in the Opal repo: https://github.com/opal/opal/issues/941
As well as this thread in the Ruby issue tracker that devolves into pure chaos with Ada refusing to actually participate in any of the valid points others bring up: https://bugs.ruby-lang.org/issues/12004
And I'm sure there's many other instances if you look around a bit.

Launch HN: Pynecone (YC W23) – Web Apps in Pure Python
So ruby has a JS transpiler - opal - https://opalrb.com/
I tried using it a little bit but the reality is if you need JS to make your app more interactable it's really worth it to just learn some JS. As soon as you need something complex the extra layer of abstraction just gets in the way and becomes more of a headache, and if you don't need anything complex then you don't need JS in the first place.

DebunkThis: Coraline Ada Ehmke hasn't really contributed that much as far as code goes
I stumbled upon this thing from years ago. I did some more digging to see what other communities thought about it. Turns out that a lot of people are really against Coraline's side.

Open Source Adventures: Episode 59: What Opal Ruby is not
It's possible to build a framework on top of Opal Ruby, like notably Hypestack, which uses uses Opal and React. There are also some wrappers like opal-jquery, and I even created opal-d3 once upon a time, but I don't actively maintain it anymore.

You can use opal-jquery, which is a wrapping layer over jQuery and in its API it combines the best worlds of jQuery and Ruby.

Using Opal Ruby with Rails 7
Next, let's refactor the code to utilize Opal jQuery in Ruby instead of plain Opal. This simplifies the code in app/assets/javascript/application.js.rb quite a bit:

Opal 1.3 released
Opal itself is a low-level thing, not depending on Rails whatsoever. We provide an official Gem for integration with Rails that integrates everything nicely and allows you to have .rb files in your JavaScript assets directory. Unlike Rails, Opal is not opinionated, to interface with web browser APIs properly you need to either use a library that wraps DOM directly, use a similar one that wraps jQuery or use Hyperstack, a fully-fledged Rails-integrated framework based on React that also allows you to share your models between frontend and backend. It's also possible to not use any of those and interface JavaScript APIs directly using an API that looks like this: $$[:document][:location].replace("https://opalrb.com/") or simply embed JavaScript with a backtick notation: `document.location.replace(#{@url})`.
