"Ruby Opal + React + ActiveRecord = GOODNESS!"
This is a very interesting project. It basically allows you to write ActiveRecord interactions in your client-side code. Things like User.find_by_email("email@example.com") will actually call the server and return a model with the real data and real methods made available by your AR model's code file. It's not ready for prime time yet and docs are still in the works, but I'll be keeping a sharp eye on this one!
