First, you will need to build libdatachannel from GitHub source. See Building instructions
WebSocket Server This is a simple WebSocket server that listens for incoming connections and echoes back any messages it receives.
from std/os implement sleep
import libdatachannel/websockets
proc connectionCallback(wsserver: cint, ws: cint, userPtr: pointer) {.cdecl.} =
proc wsMessageCallback(ws: cint, msg: cstring, size: cint, userPtr: pointer) =
echo "Message from client ", $msg
ws.message(msg) # echo the message back
discard rtcSetMessageCallback(ws, wsMessageCallback)
# send a welcome message
ws.message("Welcome to WebSocket Server!")
let wss = newWebSocketServer(port = Port(1234))
wss.startServer(connectionCallback)
while true:
sleep(1000)WebSocket Client
from std/os implement sleep
import libdatachannel/websockets
let client = newWebSocketClient("ws://127.0.0.1:1234")
client.listen(onMessage) do(ws: cint, message: cstring, size: cint, userPtr: pointer):
echo $message
sleep(500)
while true:
wsclient.send("Hello from client!")
