Can't get websockets to work on 0.15.0

[efim]

Hello!

In trying to stream in websocket, I'm stuck on an error - somewhere in init-websocket: console log:

WebSocket connection to 'ws://0.0.0.0:5153/api/subscribe' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
$p_Lio_laminext_websocket_WebSocket__initWebSocket__V

When I print to console all "messages" from the websocket - all I get is:

PlanningPokerUrgh.scala:65 got state Error(io.laminext.websocket.WebSocketError$: WebSocket error)
(anonymous) @ PlanningPokerUrgh.scala:65
PlanningPokerUrgh.scala:65 got state Closed([object WebSocket],false)

I've checked with "websocat" - the server responds without a problem and I've checked with direct javascript connection hardcoded into "main.js" - I also receive the responses

It looks as though Laminext closes websocket before it reaches the server

this is how i create websocket

and the vite forwards it's standard "ws://0.0.0.0:5153/api/subscribe" request into "0.0.0.0:8080" port of the server which can be compiled and launched with sbt backend/assembly && java -jar ./backend/target/scala-3.2.0/backend-assembly-0.1.0-SNAPSHOT.jar

I'll try to privide a more minimal example than that whole repo ( at this commit )

I'm at a loss of what to try next to trouble shoot!

P.S - i've downgraded laminar and laminex dependencies, but for some reason there's the same problem - direct javascript websocket connection from main.js works, but connection from scalajs - error's out immediately

got state Error(io.laminext.websocket.WebSocketError$: WebSocket error) PlanningPokerUrgh.scala:65:14 got state Closed([object WebSocket],false) PlanningPokerUrgh.scala:65:14

This raises chances of me not using the library in a correct way, Unfortunately I still have no idea what to do to fix things

I've went searching for imports of laminext Websocket in other projects on github

So, I've tried to do instead of

  val roomStateWSStreamBad = io.laminext.websocket.WebSocket
    .url("ws://0.0.0.0:5153/api/subscribe")
    .string
    .build(
      managed = true,
      autoReconnect = false,
      reconnectDelay = 1.second,
      reconnectDelayOffline = 20.seconds,
      reconnectRetries = 1
    )

init websocket as

  val roomStateWSStreamGood = io.laminext.websocket.WebSocket.path("/api/subscribe").string
    .build(
      managed = true,
      autoReconnect = false,
      reconnectDelay = 1.second,
      reconnectDelayOffline = 20.seconds,
      reconnectRetries = 1
    )

And things started to work. first attempts connection at Firefox can’t establish a connection to the server at ws://0.0.0.0:5153/api/subscribe.

and the second: ws://0.0.0.0:5173/api/subscribe

So the problem I was trying so solve so a couple of hours was in actuality misspelling of the port, sorry for the inconvenience, thank you for attention =0

! A good reason to use "path" instead of "url" !

Ouch, sorry you had to dig through this. Bug glad that it worked after all :)
