Ejemplo

// Stream de logs en tiempo real
const { data: logs, isStreaming, start, stop, clear } = useWailsStream<string>({
  streamName: 'app:logs',
  startFn: () => StartLogStream(),
  stopFn: () => StopLogStream(),
  bufferSize: 500,
  autoStart: true,
})

// Versión simplificada para logs
const { data: logs } = useWailsLogs('deploy:logs')

Notas

Protocolo de stream: Go emite chunks en {streamName}, completa con {streamName}:complete, errores con {streamName}:error. Buffer circular con tamaño configurable.
