How to set the event name for server sent events (SSE) in Quarkus

Question

I have following Quarkus resource:

@Path("/myResource")
class MyResource {
    @GET
    @Path("/eventStream")
    @Produces(MediaType.SERVER_SENT_EVENTS)
    @SseElementType(MediaType.APPLICATION_JSON)
    fun stream(): Multi<MyDto> = deviceStatusService.getStream()
}

This will produce events without event name and only the data section. How can I specify an event name?

Answer 1

My final code is now:

    @GET
    @Path("/eventStream")
    @Produces(MediaType.SERVER_SENT_EVENTS)
    @SseElementType(MediaType.APPLICATION_JSON)
    fun stream(@Context sse: Sse, @Context sseEventSink: SseEventSink) {
        deviceStatusService.getStream().subscribe().with { deviceStatus ->
            sseEventSink.send(sse.newEventBuilder()
                        .name("deviceStatus")
                        .data(deviceStatus)
                        .build())
        }
    }
