- For
- TypeScript developers building realtime shared-state applications
- Worth noticing
- The demo uses an in-memory transport and simulated 220 ms latency to expose optimistic updates and reconnect behavior.
Field notes
The homepage models a channel as a schema, initial value, and constrained set of changes, then runs the same reducer on clients and the hub. Its counter demo exposes the timing model directly: the transport stays in memory, latency is simulated at 220 ms, and a disconnected client can be watched catching up. The page also separates persisted actions from live-only notifications, giving developers a concrete vocabulary for different kinds of realtime traffic.
