How to implement PubSub WebSockets using Elysia?

[ocodista]

On the Bun documentation there is a section for Pub/Sub Websockets, but Elysia doesn't.

You should be able to use Pub/Sub just like Bun.

const app = new Elysia()
	.ws('/', {
		open({ subscribe }) {
			subscribe('topic')
		},
		message({ publish }) {
			publish('topic', 'message')
		}
	})

And how would you subscribe to a certain topic using Eden Treaty for example? I think we need more docs on this. @SaltyAom

topic subscribe is on server side

How would the client know about the available topics? Say you are building a chat app with chat rooms. They rooms will be created by the users/clients. So there should be a way to subscribe to those on the client, and the server should receive them dynamically. Using Eden Treaty for example, how would I do this?

It js just websockets.
U subscribe and publish to topic on server-side
Client didn't know about yours topics
Please refer to Bun websocket documentation

That's not how I used to do it with Socket.IO or Phoenix (Elixir). But it's Bun so I get it's different. Thanks for replying @kravetsone!
