Rails has an --api option and most of the Rails roles offered by recruiters these days are a combination of Rails and React, Vue or Angular. Rails assets are served with webpack and there are options for React, Vue and Angular when creating a new Rails app.
Yes but Rails is still optimized for REST CRUD apps. It's great at those apps. I use it to develop those kinds of apps. But when you want something super reactive and customized and interactive and dynamic and real-time, I reach for Node.
If I wanted something super reactive, truly concurrent and real-time there are many better options than Node - Elixir, Golang and Clojure to name a few. I just don't get the Node hype - it's not the best tool for anything other than allowing JS devs to pass themselves off as back-end experts.
