Hi Zlatko, thanks for the detailed answer :)
My client is IoT and this brings some limitations...
First I am limited by what libs I can find on the hardware side, then
the IoT can be switched off without proper signaling. And I need to
control that and react on connection loss.
I couldn't find any option for keepalive on either side of the
comunication, I am using:
IoT side: https://github.com/Links2004/arduinoWebSockets
Node.js: https://github.com/websockets/ws
We have just moved to WebSockets, I am implementing from scratch and I
am gathering information because I don't want to go through a bad path
If you or anyone, has any idea, I would be glad to hear :)
Thanks (again),
Alain Mouette

5000 timers per se should not be a problem to measure nor a problem to
the app. It's not even a strain to the connections: it amounts to
approximately 83 pings per sec, which is not too much.
But the bigger question is why do you want this? Just to keep sockets
alive? You can set this option in your websocket implementation of
choice (well, the most used ones, at least). Tell ws to do it's own
keepalive and you don't have to do bookkeeping.
If it's to relay changes in some sort of state to all the clients,
then again - why not simply sending updates as they happen? That's
kind of the advantage of websockets - if you wanted timers, you could
simply schedule regular REST requests on the client and not mess with
all of this.
