This allows ActionCable to be used in a web worker, where the `document` global is undefined. Previously, attempting to use ActionCable inside a web worker would result in this exception after you try to open a connection: ``` ReferenceError: document is not defined ``` The visibilitychange event won't ever get triggered in a worker, so adding the listener is effectively a no-op there. But the listener is mainly a convenience, rather than a critical piece of the javascript interface, so using ActionCable in a worker will still work. (And you could listen for visibilitychange yourself in a window script, then tell the worker to reconnect if you still want that behavior.) |

Action Cable – Integrated WebSockets for Rails
Action Cable seamlessly integrates WebSockets with the rest of your Rails application. It allows for real-time features to be written in Ruby in the same style and form as the rest of your Rails application, while still being performant and scalable. It's a full-stack offering that provides both a client-side JavaScript framework and a server-side Ruby framework. You have access to your full domain model written with Active Record or your ORM of choice.
You can read more about Action Cable in the Action Cable Overview guide.
