ws2s--bring socket to browser-side js

ws2s(websocket to socket) is a websocket server that handle socket(tcp)s.

the simplest workflow might be like this:

first, a websocket client(we called "ws") ask ws2s_server to create a socket(we called "s") for it.
then, "ws" ask ws2s_server to use "s" to send data.
when "s" received data, ws2s_server will notify "ws" with the received data.

with this workflow, javaScript running on a browser got the ability to use socket.

client case

a ws2s server at wss:// is ready for test case.
an online redis gui client powered by ws2s is provided at fredis.

use origin javaScript

var ws = new WebSocket("wss://")
ws.onmessage = (event) => {
    console.log("onmessage: ",
ws.onopen = () => {
            command: "connect",
            host: "",
            port: 80
            command: "send",
            data: "GET / HTTP/1.1\r\nHost:\r\nConnection: close\r\n\r\n"
ws.onclose = () => {

use ws2s.js

var socket = new WS2S("wss://").newSocket()

$('#connect-button').bind("click", () => {
    socket.connect("", 80)

$('#send-button').bind("click",  () => {
    socket.send("GET / HTTP/1.1\r\nHost:\r\nConnection: close\r\n\r\n")

socket.onRecv = (data) => {
    console.log('onRecv', data)


ws2s works on py2、py3、Linux、OSX. I tried to support Windows, but there is too much adaptation to be handled for Windows.

It is recommended to install from github:

pip install git+ --upgrade

you can also install ws2s from pypi:

pip install ws2s-python --upgrade

after installed ws2s:
ws2sd command can be used in shell,
~/.ws2s/ directory will be created when you exec ws2sd


config file is store at ~/.ws2s/config.json.



all kinds of requests are listed below:

    "command": "connect",
    "command": "send",
    "data":"GET / HTTP/1.1\r\nHost:\r\nConnection: close\r\n\r\n"
    "command": "close"

you can find out that:

  1. message(we called request) send to ws2s_sever is a json format string.
  2. a "command" field is required


message(we called response) received from ws2s_sever, is a json format string too:

    "success": true,
    "code": -1,
    "message": "recv data",
    "data": []
As the example above:    
- "message" field is for human.   
- "success" field can be ignored.     

when "code" field = -1, "data" field is presented.     
    that means ws2s_server received data from peer. "data" is a int array, each element represents a byte.     

when "code" field = 0.      
    usually means ws2s_server successfully completed the most recent command    

when "code" field > 0.      
    means something is not normal:      
    when "code" = 1:    
        unknown exception, you can submit an issue to ws2s    

    when "code" = 2:    
        ConnectionRefusedError raisesd when ws2s_server try to   
        connect host:port you specified    

    when "code" = 3:    
        IllegalSocketState, just reSend an "connect" request like:    

    when "code" = 4:    
        usually means you want ws2s_server to connect,    
        but ws2s_server refused to do that     
    when "code" = 5:    
        socket connection closed by socket server you connected to
