send() doesn't throw an error if disconnected

[timwis]

I'm implementing a broadcast function by storing an array of the clients as they join, via the connection event. The broadcast function then loops through the array and sends to each client. Since there's no disconnect event with SSEs, my thought was to wrap the send in a try/catch block and, if it throws an error, remove the client from the array so they're not in there next time. But send() doesn't seem to throw an error even if the client is long gone. So the list of clients potentially gets gigantic.

Any suggestions?

(going to cross-post upstream too)

@timwis Sorry for the delay... just saw this. As you've already pointed out, this really should be an upstream fix. Honestly, my approach was to hack around this... I use NGN data models with TTL to expire a connection after a given period of time. Far from ideal.
