WebSockets for JavaScript targets.

Example: cmd: -b:js -d:nodejs -r:off

import src/nodejs/jswebsockets
var socket = newWebSocket("ws://echo.websocket.org/")
socket.onopen = proc (e: Event) =
  echo("sent: test")
  socket.send("test")
socket.onmessage = proc (e: MessageEvent) =
  echo("received: ", e.data)
  socket.close(StatusCode(1000), "received msg")
socket.onclose = proc (e: CloseEvent) =
  echo("closing: ", e.reason)

Types

MessageEvent {.importc.} = object of Event data*, origin*: cstring
ReadyState {.pure.} = enum Connecting = 0, Open = 1, Closing = 2, Closed = 3

WebSocket {.importc.} = ref object of EventTarget url*, protocol*: cstring readyState*: ReadyState onopen*: proc (event: Event) onclose*: proc (event: CloseEvent) onmessage*: proc (event: MessageEvent)
