QUESTION
Trying to run deno locally for a deno deploy app which supports broadcast channel but getting this compilation error how do I fix it?
...ANSWER
Answered 2021-Dec-28 at 02:12It's in the stable docs for v1.17.1
, so shouldn't need --unstable
to use it:
https://doc.deno.land/deno/stable@v1.17.1/~/BroadcastChannel
Compare with unstable: https://doc.deno.land/deno/unstable@v1.17.1
However, in reality that's not the case:
QUESTION
How do I tell if Broadcast channel exists and its subscriber count?
We have a product link, and some chrome page tabs are subscribing to a Broadcast channel. Want to see how many are listening.
...ANSWER
Answered 2020-Aug-08 at 09:51There is no built-in way to get the count of active ports connected through the same BroadcastChannel.
You could set up something on your own, e.g by using some pinging method where all the ports would respond and the asker just has to count the responses in a given time, but that's a bit cumbersome, makes everything async and actually using LocalStorage just for this count seems like the easiest way.
You can keep in the localStorage the current count of each channels you'll open.
Before each new connection the page can just check that value, since it will shared across the contexts that can communicate through the BroadcastChannel.
