How to use sync controller

Prerequisites

• Runtime setup already integrated in app code.
• Familiarity with PlaybackSnapshot projection.

Steps

1. Create a controller.

const sync = createLegatoSync({
  onSnapshot: (snapshot) => setPlaybackSnapshot(snapshot),
  onEvent: (eventName) => console.log('event', eventName),
});

2. Start sync.

await sync.start();

3. Read current snapshot when needed.

const current = sync.getCurrent();

4. Force a resync after app-specific lifecycle transitions.

await sync.resync();

5. Stop and cleanup.

await sync.stop();

Expected Result

Your app maintains a local playback snapshot that starts from getSnapshot() and updates from subscribed events, with deterministic cleanup on stop.
