How detect if a client disconnected?

[derwaldgeist]

First of all, thanks for that great replacement for meteorhacks:streams. It took me only minutes to make the switch. However, I am missing one feature that was available in the streams package: To define a function that is called when the connection to the client is lost. In streams, this was possible using this.onDisconnect in an on() event handler.

+1, any update on that?

sry for the huge delay.. 😞

but is there any reason to have this information on the stream package? you can do it on meteor level: https://docs.meteor.com/api/connections.html#Meteor-onConnection (look at onClose)

In my case I wanted to reset a property from the User model whenever it disconnects from the stream.

This property is usually set right after "subscribing" to the stream, erasing its previous value and setting it to the new.

However when it is not set, it should be undefined instead of having the previous value and I can't depend on the client to reset everytime.
