# Interceptors

Source: https://docs.nestjs.com/websockets/interceptors

There is no difference between [regular interceptors](/interceptors) and WebSocket interceptors. The following example uses a manually instantiated method-scoped interceptor. As with HTTP-based applications, you can also use gateway-scoped interceptors (i.e., decorate the gateway class with `@UseInterceptors()`). Global interceptors registered with `app.useGlobalInterceptors()` or the `APP_INTERCEPTOR` token apply to gateways as well.

```typescript

@UseInterceptors(new TransformInterceptor())
@SubscribeMessage('events')
handleEvent(client: Client, data: unknown): WsResponse<unknown> {
  const event = 'events';
  return { event, data };
}
```
