Middleware

convert any WSGI compatible web framework to Websocket+HTTP framework using middleware.

works with many WSGI compatible servers

can used with any WSGI compatible web framework

Flask, Django, Pyramid, Bottle, ... supported

This middleware adds wsgi.websocket variable to WSGI environment dictionary.

example with bottle:

from bottle import request, Bottle
from wsocket import WSocketApp, WebSocketError, logger, run
from time import sleep

logger.setLevel(10)  # for debugging

bottle = Bottle()
app = WSocketApp(bottle)
# app = WSocketApp(bottle, "WAMP")

@bottle.route("/")
def handle_websocket():
    wsock = request.environ.get("wsgi.websocket")
    if not wsock:
        return "Hello World!"

    while True:
        try:
            message = wsock.receive()
            if message != None:
                print("participator : " + message)
                
            wsock.send("you : "+message)
            sleep(2)
            wsock.send("you : "+message)
            
        except WebSocketError:
            break
            
run(app)

you should use HTTP version 1.1 Server with your WSGI framework for some clients like Firefox browser
