Describe the problem
Haven't found a single mention of error handling. Nothing in google results or github issues either. How should I catch errors? (from exceeding limits for example) Should I just wrap the channel subscription in a try-catch block? Thank you.
the two places that a channel subscriber can check are upon initial subscription and during an active subscription.
when a channel is attempting to subscribe it can check the status:
...
myChannel.subscribe((status) => {
console.log(status)
if (status !== 'SUBSCRIBED') { return }
...
})
in order to check if a channel has been rate limited or there was an issue with postgres changes the channel can subscribe to system messages. see https://github.com/supabase/realtime/issues/282#issuecomment-1287221414 and https://supabase.com/docs/guides/realtime/protocol#system-messages for more details.
