Ruby on Rails, from MVC to GraphQL

As a Ruby on Rails developer, I'm always looking for the best tools and practices to apply to my day-to-day development. This framework has a fantastic structure where all its inner parts communicate very well. But, as applications start growing, or developers want to start using more modern technologies, several things start getting out of control.

Recent versions of Rails implemented Webpack, facilitating the use of modern JavaScript frameworks, which added another level of robustness to everyone's applications. Not only is this becoming the new standard, but it also enables bigger code-bases without falling into madness.

Facebook, as the creator of ReactJS (one of these modern JS frameworks and the most popular one) introduced to the world another of its technologies, GraphQL. This tool, like any other tool, can be a great asset, as long as it's in the right hands, meaning that you first need to know what role it plays before exploring how to use it in your RoR appli

This controller can be put on body or any other element.

1. Adds a websocket accessor to the element
2. Controller exposes a connected boolean getter
3. Controller bails with a warning if no shared consumer is available
4. Element will have data-action-cable-connected or data-action-cable-disconnected attributes which can be used for CSS selectors
5. Element will emit action-cable:connected or action-cable:disconnected events only when state is flipping
6. Errors => Disconnected to keep things simple

I intend to document the navigator.onLine accessor and the window:online/offline events so devs can handle PWA modes.
