## Ejemplo
|
|
|
|
```go
|
|
// Emitir evento tipado
|
|
WailsEmitEvent(ctx, "price:update", PriceData{Symbol: "BTC", Price: 67500.0})
|
|
|
|
// El frontend lo recibe con useWailsEvent:
|
|
// useWailsEvent({ eventName: 'price:update', onEvent: (data) => ... })
|
|
```
|
|
|
|
## Notas
|
|
|
|
El evento llega al frontend como WailsEventPayload con `type`, `data` y `timestamp`. Complementa `use_wails_event` del lado TS. Requiere la dependencia `github.com/wailsapp/wails/v2` en el proyecto destino.
