I need a help

[jorgebg2016]

I would like to know whether is possible to call a function outside the server class handler. I have to emit datas from my Python modules for the Javascript events handler. Somebody can help me?

Not sure I understand your question. But I think this example that I also stole from somewhere here :)

import threading
import time
import json
import logging
import websockets
from queue_helpers import deque


from SimpleWebSocketServer import SimpleWebSocketServer, WebSocket

USERS = set()

class SimpleEcho(WebSocket):
	def handleMessage(self):
		self.sendMessage(self.data)

	def handleConnected(self):
		USERS.add(self)

	def handleClose(self):
		USERS.remove(self)

server = SimpleWebSocketServer('', 8888, SimpleEcho)
# server = SimpleWebSocketServer('', 8888, SimpleEcho, selectInterval=0.1)

def push_out_news():
	while True:
		news_item = deque()
		if USERS and news_item:
			for user in USERS:
				user.sendMessage(str(news_item))
		time.sleep(0.2)

if __name__ == '__main__':
	t = threading.Thread(target=server.serveforever)
	t.setDaemon(True)
	t.start()
	push_out_news()
