Volt Introduction and Docs


Controllers provide a #channel method, that you can use to get the status of the connection to the backend. Channel's access methods are reactive and when the status changes, the watching computations will be re-triggered. It provides the following:

method description
connected? true if it is connected to the backend
status possible values: :opening, :open, :closed, :reconnecting
error the error message for the last failed connection
retry_count the number of reconnection attempts that have been made without a successful connection
reconnect_interval the time until the next reconnection attempt (in seconds)

Channel Events

Sometimes you need to run code when the client connects or disconnects to/from the server. In a controller on the client you can do:

channel.on('connect') do
  .. connected ..

channel.on('disconnect') do
  .. disconnect ..
