# `DemoDirector.PlaybackChannel`
[🔗](https://github.com/ralmidani/demo_director/blob/v0.1.1/lib/demo_director/playback_channel.ex#L1)

Phoenix channel that relays playback JS from the server to every
connected overlay.

When the channel joins it subscribes to the
`"demo_director:playback"` PubSub topic on the host app's
configured pubsub server. The `mix demo_director.play` task
broadcasts on that topic; this channel pushes each broadcast to the
joined client.
