Websocket & SSE

[treagod]

Is there a possibility to use Websocketd or Server Side Renderinng with Marten?

I tried the ReponseStream, but I don't understand how I can spawn a Fiber, hold the connection and only emit data when needed. As far as I understand Marten only emits whole response, but not partial ones

Hey! 👋

Marten does not support Websockets at the moment. This is something that I envision we could add to the framework in 2024 though.

Regarding streaming responses, which Marten supports, those are intended to be used to "stream" a lengthy response back to the client (eg. a large dynamically generated file). They can't be used to hold a connection forever: when the content is fully streamed, the connection is closed.

Hope that helps!

Are you also planning to integrate SSE for simpler use cases in addition to websockets? Or generally make it possible to outsource a request to a fibre so that it no longer blocks?

Yes, this is also something I plan to add to the framework at some point.
