tcp protocol not avalible (websocket)

[DAT4]

Hi. I made a online multiplayer game in Ebiten, and I wanted to use wasmserve to make it possible to run the game from a browser.

1. First I wanted to download the map with a http.Get("https://domain.ext/map.json"), but I got a CORS error, I tried using the -allow-origin "*" flag to get around it. It didnt help anything. So I hardcoded the map into the code and then I could start the application.

2. Next step is to login. So I am writing my username and password on the screen and everything works. I send the credentials and I receive the Token.

3. The next step is to connect to the websocket connection in the backend. I am using gorilla/websocket and I write

u := "ws://localhost:8056/join"
log.Printf("connecting to %s", u)
header := http.Header{}
header.Add("Authorization", "bearer "+token
websocket.DefaultDialer.Dial(u, header)

wasm gives me this error:

2021/03/28 14:05:31 connecting to ws://localhost:8056/join wasm_exec.js:51:14
2021/03/28 14:05:31 dial tcp: Protocol not available

And my program crashes.

Is this because wasmserve does not support websocket or am I doing something wrong?

Best regards Martin Maartensson.

EDIT:
I just found out that its actually gorilla/websocket which doesn't support wasm, so an alternative could probably be to use nhooyr/websocket instead of gorilla/websocket.
