<@U1ZQ36CJD> have you tried `ConflatedBroadcastChannel` for broadcasting?

@spierce7 have you tried ConflatedBroadcastChannel for broadcasting?

[spierce7]

My understanding was that ConflatedBroadcastChannel is similar to an AsyncSubject. What if I wanted something similar to a PublishSubject?

[enleur]

Not sure what PublishSubject actually does, but in ConflatedBroadcastChannel when you publish messages and there are no subscribers, these messages will be lost. Subscribers will get only messages that were posted after their subscription

[spierce7]

Oh? That sounds like a PublishSubject then.

[enleur]

Just give it a try 🙂

PublishSubject == BroadcastChannel(0), BehaviorSubject == ConflatedBroadcastChannel (which has a buffer of one, which is the latest value of the channel, but there's an open pull request to make this even better...)

[dave08]

As far as I remember of Rx, since I dumped it for a while now because of coroutines...

[spierce7]

oh? Maybe I'm misunderstanding the way channels work then.

The pull request is here https://github.com/Kotlin/kotlinx.coroutines/pull/274 , this pull is becoming more like a BehaviorRelay

Did you read the ' Rx Subject vs BroadcastChannel' in https://github.com/Kotlin/kotlinx.coroutines/blob/master/reactive/coroutines-guide-reactive.md
