@loicboutet going to put in my $0.02 on Volt. Its a bit early, but you will be able to build anything in it. The live updating is only one small feature. You can also do bindings that don't live update (here's a video showing that: https://www.youtube.com/watch?v=c478sMlhx1o)
I think the big win with volt is sharing code between client and server. I'm working on a demo that should the sharing better
Interesting idea @loicboutet but I wonder if part of Volt’s appeal is that it’s a rack-app, built for the modern web - so might be less bloated and dare I say it, more scalable? (No idea if that’s actually the case)
Maybe bloated wasn’t a good word to use - but Rails is getting on now, there may well be stuff there that is a little outdated. Having said that, I do love Rails. The only thing I currently dislike is that they haven’t or have no plans to adopt Opal.
