  The Ruby Spec Suite aka ruby/spec (by ruby)

  

Opal is simply a Ruby to JavaScript compiler. While it may be someday possible to run Rails on it, as you can run Rails on JRuby, the primary focus of this project is to allow you to write frontend code in Ruby and possibly share some code between your frontend and backend. It's possible to compile entire Ruby libraries to JavaScript (with little changes needed due to some caveats). Opal supports a Ruby 3.0 level of features (regardless of your backend Ruby version), often surpassing MRuby in terms of compatibility. It is being actively tested for regressions against Ruby Spec and is self-hosting, ie. can compile itself (see: TryRuby).

  Ruby ♥︎ JavaScript

  

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})`.

• opal-devtools

  A Browser extension providing tools for developing with Opal Ruby in the browser.

  

If you have source maps - things should work well (unless you strip them and minify the code). But in web console you still need to speak JavaScript (unless you have this: https://github.com/isomorfeus/opal-devtools - but I don't think it will work with the current version). Fortunately, Opal API for JavaScript is pretty straightforward, though at least a little bit verbose: https://opalrb.com/docs/guides/v1.3.1/compiled_ruby
