+## Ejemplo
+
+```tsx
+// Escuchar eventos de Go
+const { lastData, eventCount, emit } = useWailsEvent<PriceUpdate>({
+  eventName: 'price:update',
+  onEvent: (price) => updateChart(price),
+})
+
+// Emitir de TS a Go
+emit({ symbol: 'BTC', action: 'subscribe' })
+```
+
+## Notas
+
+Exporta también `useWailsEmit()` para emit sin suscripción. Usa `window.runtime.EventsOn/Off/Emit` del Wails runtime.
