Hey, I found on youtrack that there appears to be plugins for sse for both server and client in 3.0.0, is it written anywhere which eap artifacts are needed to experiment with this? Sorry if it’s obvious and I couldn’t find it

You can check out the SSE plugins (

io.ktor:ktor-server-sse

and

io.ktor:ktor-client-core

) using the

3.0.0-eap-786

version.

I can’t seem to get a combination of

io.ktor:ktor-server-sse:3.0.0-eap-786

and

io.ktor.plugin

to run, any advice? Also on another note we use

Resources

for all other endpoints - is it possible to use it with

sse

to avoid having to define the path manually? Thanks again

Unfortunately, the current version of the Ktor Gradle plugin is incompatible with the EAP version. You can use the constructor of the

SSEServerContent

class to send SSE events in the handler of a resource route.

Copy code

embeddedServer(Netty, port = 4444) {
    install(SSE)
    install(Resources)
    routing {
        get {
            call.respondText(contentType = ContentType.Text.Html) { """
                <html>
                    <body>
                    <script>
                        const evtSource = new EventSource("/sse");
                        evtSource.onmessage = (event) => {
                            console.log(event.data);
                        };
                    </script>
                    </body>
                </html>
            """.trimIndent() }
        }
        get<SseEndpoint> {
            call.respond(SSEServerContent(call) {
                send(ServerSentEvent("hello"))
            })
        }
    }
}.start(wait = true)

That’s great thanks! Any chance of blog post / news talking about the road to 3.0 any time soon? 😁
