Due to the fact that browsers do not support using tcp and udp directly, the client side should use websocket instead.
js.Global().Get("WebSocket").New("ws:https://localhost:8080/echo")- Build Webassembly
make build-wasm
- Run TCP server
cd server
go run server
- Host
index.htmlwith the HTTP server
python3 -m http.server 8000
-
Open
http:https://localhost:8080in your browser. -
Now you can see the client connect to the TCP server in terminal
