Module: ActionCable::Server::Connections

Included in:
Base
Defined in:
lib/action_cable/server/connections.rb

Overview

Collection class for all the connections that have been established on this specific server. Remember, usually you’ll run many Action Cable servers, so you can’t use this collection as a full list of all of the connections established against your application. Instead, use RemoteConnections for that.

WebSocket connection implementations differ on when they’ll mark a connection as stale. We basically never want a connection to go stale, as you then can’t rely on being able to communicate with the connection. To solve this, a 3 second heartbeat runs on all connections. If the beat fails, we automatically disconnect.
