Ejemplo

// 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.
