Legato Facade

Legato is exported as LegatoApi & LegatoEventApi and combines audioPlayer + mediaSession with a single addListener signature over LegatoEventName.

Composition

In plugin.ts, Legato is composed as:

export const Legato = {
  ...audioPlayer,
  ...mediaSession,
  addListener: addLegatoListener,
  removeAllListeners: sharedDelegate.removeAllListeners,
};

Interface summary

Surface	Included
Playback setup, queue, transport, queries, capabilities	✅ from audioPlayer
Media-session listener surface	✅ from mediaSession
Unified listener (LegatoEventName)	✅ via Legato.addListener

Listener behavior

Legato.addListener delegates to LegatoModule.addListener, like the namespace-specific helpers.

const h = await Legato.addListener('playback-state-changed', ({ state }) => {
  // sync your UI store
});

await h.remove();
