## Usage
2023-12-24 16:10:10 +00:00
This package exposes `PubSubSynchronizationChannel` , which can simply be dropped into any `AngelWebSocket` constructor. Once you've set that up, instances of your application will automatically fire events in-sync. That's all you have to do to scale a real-time application with Angel3!

await app.configure(AngelWebSocket(

synchronizationChannel: PubSubSynchronizationChannel(

pub_sub.IsolateClient('< client-id > ', adapter.receivePort.sendPort),
2017-08-08 21:04:36 +00:00
),
));
