## Ejemplo
|
|
|
|
```go
|
|
// Stream de slice
|
|
WailsStreamData(ctx, WailsStreamConfig{
|
|
StreamName: "logs",
|
|
ChunkDelay: 10 * time.Millisecond,
|
|
}, logLines)
|
|
|
|
// Stream con generador
|
|
WailsStreamFunc(ctx, "metrics", func(ctx context.Context, ch chan<- Metric) error {
|
|
for {
|
|
select {
|
|
case <-ctx.Done():
|
|
return nil
|
|
case <-time.After(time.Second):
|
|
ch <- collectMetric()
|
|
}
|
|
}
|
|
})
|
|
|
|
// Frontend lo recibe con useWailsStream:
|
|
// useWailsStream({ streamName: 'metrics', autoStart: true })
|
|
```

## Notas
|
|
|
|
Protocolo: chunks en `{streamName}`, fin en `{streamName}:complete`, error en `{streamName}:error`. Compatible con `use_wails_stream` del lado TS. WailsStreamFunc usa goroutine + canal para datos asíncronos. Requiere Go 1.18+ (generics) y la dependencia `github.com/wailsapp/wails/v2` en el proyecto destino.
